How to Choose a Mattress?

Buying a new mattress is a big decision. You'll sleep on it every night for years, and a store test of a few minutes can't tell you how it will feel after a month. There's no magic formula either: every mattress is built differently, and every sleeper is different too.

The good news is that choosing gets much easier when you take it one decision at a time. This guide walks you through each step in order, from budget and materials to firmness, size, thickness, the base underneath, and the trial and warranty that protect you if you get it wrong.

Read on as our sleep team walks you through finding the best mattress for the way you sleep.

Where to Start Looking for a Mattress

Start with yourself, not the store. Notice how you sleep for a few nights: which position you wake up in, whether you get too warm, whether you like to sink in or lie on top of the bed, and whether a partner's movement wakes you. If you share the bed, ask your partner how you sleep, and how they like to sleep too.

Next, note what you like and dislike about your current mattress, and set a budget you're comfortable with. Then work through the decisions below in order. Each one narrows the field, so you end up comparing a handful of good options instead of hundreds.

1. Set your budget and pick a material

   Innerspring, memory foam, latex or hybrid. The material decides the overall feel, how warm the bed sleeps, how long it tends to last and much of the price.

2. Choose a firmness

   Match it to your sleep position and body weight, then to your own preference.

3. Pick a size

   Check your bed frame, the room and who (and what) shares the bed.

4. Decide on thickness

   Most adults are comfortable on 10 to 12 inches; heavier sleepers often want more.

5. Check your base

   Make sure your bed frame or foundation suits the mattress and keeps its warranty valid.

6. Read the trial, returns and warranty

   Know how long you can try it, what a return involves and what the warranty covers.

7. Verify the materials

   Look up any certification the maker claims and check which part of the mattress it covers.

Factors That Help You Decide What Type of Mattress You Need

The type of mattress shapes almost everything else: how it feels, how much it moves when your partner rolls over, how warm it sleeps and what it costs. Your sleep position, body weight and whether you sleep hot all point toward some types more than others. Here are the four main types side by side. These are general traits, and individual mattresses vary a lot with their materials and build quality.

For a deeper comparison, see our guide to innerspring vs. memory foam vs. latex vs. hybrid mattresses.

Memory foam mattresses

Memory foam softens with body heat and pressure, so it slowly molds to your shape. Many sleepers love that close, cradling feel, especially side sleepers who want cushioning at the shoulders and hips. It's also quiet and absorbs movement well, so a restless partner is less likely to wake you.

Latex mattresses

Latex foam is made from natural rubber tree sap, synthetic rubber or a blend of the two. It contours enough to ease pressure, then pushes back right away, so it feels buoyant rather than sinking. Most latex has pinholes that let air move, and an all-latex mattress has no coils to squeak. Our latex mattress guide answers the most common questions.

You'll see two kinds of latex foam, named after how they're made. Dunlop latex is poured into a mold and baked; it's typically denser, with a solid, springy feel. Talalay latex is vacuum-expanded and flash-frozen before baking; it's typically lighter, with an airy, bouncy feel. Both come in soft to extra firm, and neither is "better": it comes down to the feel you prefer. Our Dunlop vs. Talalay guide explains the differences.

Innerspring mattresses

Innerspring is the classic mattress: a unit of steel coils with padding on top. It's usually the most affordable type and has a bouncy, cool feel that many people grew up with. True innersprings are less common now, because many have added foam on top and moved closer to a hybrid.

Hybrid mattresses

Hybrid mattresses combine a core of individually pocketed coils with comfort layers of foam, latex, wool or cotton on top. You get coil bounce and airflow underneath and cushioning above, which is why hybrids are popular with couples and combination sleepers. Quality varies a lot, so check what the comfort layers are made of and how thick they are.

Airbeds and waterbeds

Air mattresses are inflatable, and you can add or let out air to change the feel. Most are used for camping or guests, though some are made for everyday use. Waterbeds use a frame or foam shell filled with water. They have a distinctive floating feel, but they need regular upkeep, they're very heavy when full and a puncture can leak. Most people choosing an everyday mattress pick one of the four main types above.

Budget

It helps to know what your budget can buy before you fall in love with a mattress. Prices change often and vary by brand, so rather than chase a number, look at what drives the cost:

• Materials: natural and certified organic materials cost more to make than synthetic ones.
• Construction: more layers, thicker comfort layers and better coils add cost.
• Size and thickness: bigger and thicker mattresses use more material.
• Custom sizes: oversized beds such as an Alaskan King are usually made to order and cost more.
• Trial and warranty: a long trial and warranty add value that doesn't show on the price tag.

Roughly, innerspring and basic foam mattresses sit at the lower end, most foam and hybrid mattresses in the middle, and natural latex, latex hybrids and certified organic mattresses toward the top. A cheap mattress that wears out quickly can cost more in the long run than one that lasts, so compare cost per year of use, not just the sticker price. If you can wait, holiday sales are a good time to buy (see "Best time to buy a mattress" below).

How to Choose Mattress Firmness by Sleep Position and Body Weight

Firmness is how hard or soft a mattress feels when you first lie on it. Many brands rate it on a 1 to 10 scale, from 1 (very soft) to 10 (very firm), but there's no industry standard, so one brand's "medium" can feel like another's "firm." Use the scale as a starting point and trust your own comfort. Our mattress firmness scale explains each level in detail.

Sleep position and body weight are the two biggest factors in which firmness feels right. This chart is a starting point, and personal preference always wins.

Side sleepers

Most of us spend at least part of the night on our side. Your shoulders and hips carry most of your weight in this position, so many side sleepers prefer a softer or medium surface that lets them sink in a little. A mattress that's too firm can feel hard at those pressure points. If your mattress is otherwise fine, a topper for side sleepers can add softness on top.

Stomach sleepers

When you sleep on your stomach, your hips tend to sink the most. Many stomach sleepers find a medium-firm to firm mattress more comfortable, because it keeps them from sinking in too deep. Lighter stomach sleepers may still find a medium feel comfortable.

Back sleepers

Back sleepers usually do well in the middle of the scale. A medium to medium-firm mattress lets your hips and shoulders settle in slightly while still feeling supportive under your lower back. Latex, firmer foam and hybrid mattresses all come in feels that suit back sleepers.

Combination sleepers

If you change position through the night, look for a medium to medium-firm mattress that responds quickly. A surface that springs back, like latex or a hybrid, makes it easier to turn over than a slow, deep-sinking foam.

Body weight

Your weight changes how firm a mattress feels. Sleepers under about 130 lbs don't press as far into the comfort layers, so a firm mattress can feel harder to them than its rating suggests. Sleepers over about 230 lbs press in further, so they often prefer a firmer feel, a thicker mattress and strong edges. If you're shopping for a heavier body, our mattress weight limit guide covers what to check.

Sharing the bed

If you and your partner like different feels, choose for the heavier partner, or pick a split size. A split queen, split king or split California king lets each side have its own firmness. Turmerry's split sizes come in one zippered cover the full size of the bed, with separate latex layers for each side.

If you have pain or a health condition

Many people start shopping because they wake up stiff or sore. A new mattress isn't a treatment, though. If you have ongoing back, neck or joint pain, or a condition such as arthritis or fibromyalgia, talk to your doctor or physical therapist first, and ask whether they have any guidance for your sleep setup.

After that, choose by comfort. Many sleepers find that a mattress that cushions the shoulders and hips while still feeling supportive is the most comfortable, and that one too soft or too firm leaves them less comfortable. Because comfort is so personal, a long home trial matters even more here.

What Size Mattress Do You Need?

It's surprisingly easy to buy a mattress that doesn't match the bed frame. Measure the inside of your frame, check the room and think about who shares the bed, including kids and pets. A queen is the most popular size for couples, while twins and fulls suit kids, teens and single sleepers, and kings give couples the most room.

A few less common sizes are worth knowing about, though fewer brands make them and bedding can be harder to find:

A bigger frame can hold a smaller mattress for a while, but a mattress that's too big for the frame will hang over the edges and won't be properly supported. When in doubt, measure twice.

How Thick Should Your Mattress Be?

Thickness (or height) affects how much cushioning you get, how the bed looks and which sheets fit. Most mattresses are 8 to 12 inches thick, and 10 to 12 inches suits most adults.

Thicker isn't automatically better. What matters is that there's enough comfort material for your weight and sleep position, plus a supportive core underneath. Before you buy, add any topper to the mattress height, check that your fitted sheets have a deep enough pocket, and think about how high the bed will sit for getting in and out. Our mattress thickness guide goes into more detail.

What Base or Foundation Does Your Mattress Need?

The base under your mattress matters as much as the mattress itself. A sagging or flexing base can make a good mattress feel worn, and the wrong base can void the warranty. Most modern mattresses, including latex, memory foam and most hybrids, are designed for a flat, firm base rather than a traditional box spring.

Here's what Turmerry's warranty requires for our mattresses. Other brands set their own rules, so check yours before you buy.

If your slats are farther apart, add slats or lay a bunkie board or plywood sheet on top first. Turmerry also sells a Platform Base that replaces a box spring. For more detail, see our guides to the best foundation for a latex mattress and whether you need a box spring.

Pointers to Remember When You Set Out to Choose a Mattress

Once you know the type, firmness and size you want, a few more things separate a mattress you'll love for years from one you'll regret.

Place of manufacture

Where and how a mattress is made affects its price, shipping time and how much you can learn about it. A maker that tells you where its materials come from and where the mattress is assembled is easier to trust. Shipping a heavy mattress a long way also adds cost.

Build quality and brand

Two mattresses of the same type can feel completely different. Look past the name and read what's in every layer: the material, the thickness of each layer and, for hybrids, the coil type. A good maker lists all of this on the product page. Branded mattresses often cost more than similar local ones, so compare the specs, not just the label.

Materials

Natural and certified organic materials, such as organic latex, organic cotton and wool, usually cost more than synthetic foams and fabrics. Many shoppers choose them because they want to know exactly what they're sleeping on, and certifications let you check those claims (see the certifications section below). Read the product description for the full list of materials, and compare it with what reviewers say.

Durability and lifespan

Many mattresses last about 7 to 10 years. Latex is known to last longer, but materials, build quality, body weight, the base and care all change the picture. A cheap mattress can be a fine short-term choice, but if it wears out quickly you'll be shopping again sooner. A mattress that's well made and well cared for is usually the better buy over time. The warranty length is a useful clue to how long a maker expects its mattress to hold up.

What to Look For in a Good Quality Mattress?

Every mattress is built for a purpose, and each brand sets its own construction and firmness levels. These are the qualities worth checking on any mattress you're considering.

Support

Support is how well the mattress holds you up, as opposed to how soft it feels on top. A supportive mattress keeps you from sinking in too far, especially at the heaviest part of your body, your hips. Lighter sleepers often feel well supported on a softer bed, while heavier sleepers usually want a firmer core and more depth. Your age, weight and how you sleep all play a part, so choose what feels right for you.

Firmness

Mattress firmness usually comes in soft, medium and firm, with steps in between. What feels soft to one person can feel firm to another, and ratings aren't consistent across brands, so don't follow them blindly. Many sleepers land between about 5 and 7 on the 1 to 10 scale, but use the chart above as your guide and test the feel yourself.

Pressure relief and body contouring

Pressure relief comes from a surface that lets your shoulders and hips sink in slightly, so your weight spreads out. Memory foam contours closely and slowly, latex contours and springs back, and hybrids depend on their comfort layers. How much pressure relief you need depends on your sleep position and body weight.

Edge support

Edge support is how firm the mattress feels around its perimeter. It matters because most people sit on the edge of the bed every day, and a soft edge can make you feel like you'll roll off. Hybrids often have reinforced perimeter coils, and dense latex is fairly firm at the edges. Heavier sleepers and couples who use the whole surface benefit the most from strong edges.

Motion isolation

Motion isolation is how well a mattress absorbs movement, so one sleeper tossing and turning doesn't wake the other. Memory foam isolates motion very well, latex and pocket-coil hybrids do well, and traditional innersprings with linked coils pass the most movement along. If you or your partner are light sleepers, put this near the top of your list.

Temperature regulation

If you often wake up warm, the mattress and your bedding both play a part. Mattresses stay cooler in a few different ways:

Breathable sheets and a breathable mattress protector help too. A thick, non-breathing protector can make any mattress feel warmer.

Adjustability

Some mattresses let you change the feel after you buy them. Split sizes let each partner choose their own firmness, and adjustable bases let you raise the head or foot of the bed. Every Turmerry mattress except the Latex Hybrid has separate latex layers inside a zippered organic cotton cover. Nothing is glued or sewn shut, so you can unzip it, see the layers and rearrange them to change the feel, and you get one free layer swap if you'd like to try a different firmness.

Off-gassing and new mattress smell

Some new mattresses have a smell when you first unwrap them, especially foam mattresses that arrive compressed in a box. This is often called off-gassing. A smell doesn't automatically mean a poor mattress, and it usually fades in a well-ventilated room. If you're sensitive to smells, read reviews to see how strong it is and how long it lasts, and ask what the fire barrier is made of. Most Turmerry customers unpack their latex mattress and use it right away, though some like to air it out for a few days. Our guide on why a new mattress smells explains more.

Which Mattress Certifications Matter?

Certifications are one of the best ways to check what a mattress is made of, because an independent body has inspected or tested it. Each one covers something different, so check which part of the mattress it applies to (the latex, the cover fabric or the whole mattress) and look up the certificate number if one is given.

At Turmerry, the organic Dunlop latex in our all-latex mattresses and the DIY Hybrid is GOLS certified (Control Union, certificate CU 886641), and our organic cotton is GOTS certified (Control Union 1084143). The Organic Latex Hybrid Mattress is different: it uses FSC-certified Talalay latex, which is not GOLS certified, inside a GOTS-certified organic cotton cover. Learn more in our guides to GOLS and GOTS certification.

Other Factors That Should Help You Decide

Now for the fine print: the seller's policies decide what happens if the mattress isn't right, so read them before you buy.

Company reputation and reviews

Start by asking friends and family about the mattresses they own and the companies they'd buy from again. Word of mouth is still one of the best guides. Then read reviews on the brand's own site, independent review sites, forums and social media. A brand with mostly positive reviews and a few complaints it has answered well is a good sign. If the complaints outnumber the praise, keep looking.

Trial period, returns and refunds

Even after testing a mattress in a store, it takes time to get used to a new feel, anywhere from a couple of weeks to a few months. A home trial lets you find out at home. Trial lengths, return fees and refund rules vary a lot between brands, so read the details: how long you must try it first, whether the refund is full or partial, whether there's a pickup or restocking fee, and how many returns you're allowed.

Here's what Turmerry offers on mattresses (full details on our shipping and returns page):

• Layer swaps: if changing one layer would make your all-latex mattress feel better, we'll swap it at no charge. A layer swap doesn't count as your household's mattress return or exchange.
• Return limit: one mattress return or exchange per household, in total. After that, future mattress orders aren't eligible for a return or exchange.
• How returns work: if you'd rather return the mattress than swap a layer, we have a donation program. Contact us to start a return.

Warranty

A warranty covers manufacturing defects, not comfort preference or normal softening. Read what it covers for the specific mattress you're buying, because terms differ by model, and note the rules you have to follow, such as the base and a mattress protector. Turmerry's 7 Zone Organic Latex, Egg Crate, Dual Side Latex Flippable, DIY Hybrid, Bigg+ and Organic Kids mattresses have a 20-year limited warranty, and the Latex Hybrid and RV mattresses have a 10-year limited warranty. Body impressions deeper than 1.5 inches are covered. See the full terms on our warranty page.

Delivery and setup

Most mattresses bought online arrive in a box at your door, and you set them up yourself. Some brands offer in-home setup and old-mattress removal, sometimes for a fee, so ask before you order if you need it. Either way, get a second person to help: mattresses are heavy and awkward.

Turmerry ships free in the contiguous US, and mattresses ship within the US only. Most orders placed by 3 PM EST ship the same business day from Charlotte, NC, and arrive in 2-3 business days on the East Coast or 5-7 on the West Coast. Our zip-cover latex mattresses are easier to set up than one-piece beds, because you can carry the latex layers in one at a time, kept flat or on edge. Never bend or fold latex layers. The Latex Hybrid is one piece and moves flat, like any hybrid.

Customer service

Before you buy, find out how you can reach the company if something goes wrong: phone, email or chat, and how quickly they answer. A good test is to ask a question before you order and see how helpful the reply is. You can reach Turmerry at 984-299-6850.

Where to buy the mattress

You can buy a mattress in a store or online, and both have advantages.

Whichever you choose, read customer reviews to see whether real experiences match the brand's claims. If you're near Charlotte, you can try Turmerry mattresses at our showroom at 3300 Woodpark Blvd., Suite L, Charlotte, NC 28206 (Monday to Friday, 9 am to 5 pm ET).

Best time to buy a mattress

The best time to buy a mattress is when you need one. If you can wait, many brands run sales around holidays such as:

• Memorial Day
• Fourth of July
• Labor Day
• Black Friday

Do your research and settle on a model ahead of time, then watch for the sale announcements so you can buy as soon as the discount goes live. Our guide on the best time to buy a mattress has more tips.

What Questions Do People Have When They Are Confused About How to Choose a Mattress?

Mattress shopping can feel overwhelming, with so many options and so much to keep in mind. Here are the questions shoppers ask us most often.

1. How do you decide what type of mattress to buy?

Start by answering a few questions about yourself:

• What position do you sleep in, and do you lie still or toss and turn?
• Do you sleep warm?
• How much do you weigh?
• Do you share the bed, and does your partner like a different feel?
• Do you prefer to sink in or lie on top of the bed?
• What's your budget?
• What size is your bed frame, and how big is your room?

Your answers point you toward a type, a firmness and a size, as explained in the sections above. If you have a medical condition that affects how you sleep, talk to your doctor too.

2. Is it better to sleep on a hard or soft mattress?

Neither is better for everyone; it depends on your sleep position, body weight and preference. Many sleepers are most comfortable on a medium to medium-firm mattress, because it cushions without letting you sink too far. Side sleepers and lighter people often prefer softer, while stomach sleepers and heavier people often prefer firmer. If your doctor has recommended a specific type of mattress, follow their advice.

3. How do I know if my mattress is too soft?

Your mattress may be too soft if you sink in so far that it's hard to change position or get out of bed, if you feel like you're sleeping in a hole, or if it leaves a lasting body impression. Waking up sore or stiff can be another sign. A firmer topper won't fix a mattress that sags, so check the base and the mattress itself first.

4. How do I know if my mattress is too firm?

A mattress may be too firm if you feel pressure at your shoulders and hips, if your arm goes numb when you sleep on your side, or if you toss and turn trying to get comfortable. If you sleep better on a softer bed elsewhere, that's a good clue. A soft latex topper can add cushioning to a mattress that's otherwise in good shape. See our guide on how to make a firm mattress softer.

5. Which is better: a spring or a foam mattress?

Neither type suits everyone. Spring mattresses feel bouncy and airy and are often more affordable, while foam and latex mattresses contour more closely and pass along less motion. If you want close pressure relief and quiet, a foam or latex mattress may suit you. If you like bounce and airflow with some cushioning, a hybrid combines both.

6. How do you decide if you need a new mattress?

Worn-out mattresses share a few common signs. If you notice several of these, it's time to start shopping:

• It sags or keeps a body impression after you get up
• It creaks, squeaks or you can feel the coils
• It has stains or smells that won't clean out
• You wake up stiff or sore more often than you used to
• You sleep better on other beds, like a hotel or guest bed
• Your needs have changed, for example a new partner, pregnancy or a change in weight

Our guide to the signs you need a new mattress goes through each one.

7. How often do I need to replace a mattress?

Many mattresses last about 7 to 10 years. Latex is known to last longer, but materials, build quality, daily use and care all change the picture, so judge your mattress by its condition as well as its age. Rotating it, using a supportive base and a waterproof protector all help it last.

8. Should I replace my 20-year-old mattress?

Almost certainly. A 20-year-old mattress is well past the 7 to 10 years many mattresses last, and even one that looks fine has usually lost some of its comfort and support. If it sags, creaks or you wake up sore, replace it soon.

9. What's the best mattress for heavier sleepers?

Sleepers over about 230 lbs usually do best with a firmer feel, a thicker mattress (12 inches or more) and strong edges. Look for dense, durable materials, such as firmer latex layers, high-density foam or a sturdy pocket-coil unit, and check the mattress weight limit. Memory foam can work too, as long as it's dense and thick enough, though some heavier sleepers find it sinks too deep. Our Bigg+ Natural Latex Mattress is built for sleepers over about 230 lbs.

10. How do I choose a mattress if I have back pain?

Talk to your doctor or physical therapist first, especially if the pain is ongoing. A mattress can't treat back pain, but the right one can make you more comfortable. Many people with a sore back prefer a medium to medium-firm mattress that cushions the shoulders and hips while still feeling supportive, and find that a very soft or very firm mattress is less comfortable. Since everyone's different, buy with a long home trial so you can find out how it feels over several weeks.

11. How long should I try a new mattress before deciding?

Give it at least 30 nights. Your body needs time to adjust to a new feel, and the comfort layers need a few weeks to break in. That's why Turmerry's 120-night trial asks you to sleep on your mattress for at least 30 nights before starting a return. If it still isn't right, ask about a layer swap first: changing one layer can change the feel without a return.

The Bottom Line

Choosing a mattress is easier when you take it one step at a time: pick a material that fits your budget and the feel you like, match the firmness to your sleep position and body weight, choose the right size and thickness, give it a proper base, and read the trial and warranty before you buy. Then sleep on it for at least 30 nights before you decide.

If you'd like help, take our mattress quiz for a personal suggestion, or call us at 984-299-6850. If you have ongoing pain or trouble sleeping, talk to your doctor.
