King Mattress Topper FAQs

What is the best mattress topper for a king bed?

A king-size mattress topper is the best mattress topper for a king bed. Its dimensions match those of a king bed (76 x 80 inches), ensuring that it isn't too small or too big.

Do mattress toppers make a big difference?

Mattress toppers can make a big difference for most mattresses. They can improve the lifespan of a brand-new mattress and/or offer additional cushioning plus support for your current mattress. Moreover, mattress toppers can be beneficial for improving sleep.

However, your current mattress mustn't be too old to the point where it has begun to droop and sag. In such cases, a topper might not be able to make a big difference.

What are the dimensions of king-size mattress toppers in inches, centimeters, and feet?

Dimensions of king-size mattress toppers in Inches - 76 x 80 inches

Dimensions of king mattress toppers in Centimeters - 193 x 203.2 cm

Dimensions of king mattress toppers in Feet - 6.33 x 6.66 feet

How many inches of a mattress topper is best?

Mattress toppers between 2-4 inches are considered ideal. Thinner mattress toppers are the perfect choice for those who desire a slightly cushioning extra layer above their new beds. Thicker mattress toppers are a great choice for those who desire a lot of cushioning above their old beds.

Do you need bigger sheets with a mattress topper?

Yes, you may need larger sheets to accommodate the added height of a mattress topper. It's advisable to opt for fitted bed sheets with deep pockets. A fitted sheet can often ensure a secure and comfortable fit. For added convenience, choose a removable cover, a washable cover, or both.

Putting a fitted sheet over bed

Is it a good idea to buy a mattress topper/mattress pad in place of a mattress?

It is not recommended to buy a mattress topper/mattress pad in place of a mattress. Mattress toppers and mattress pads exist as bedding additions to mattresses, enhancing their comfort and lifespan.

Using a mattress topper/mattress pad without a mattress beneath it means you'll get very minimal support and comfort. Sleeping every night on a simple mattress topper/mattress pad could even result in health issues like lower back pain.

Who should buy a king latex mattress topper?

A king latex topper is suitable for individuals who have a king mattress and want to enhance its comfort and support by adding an extra layer of cushioning.

Toppers of this size can be particularly beneficial for sleepers who like to enjoy the comfort of the extra space, such as those who:

  • Share their bed with a partner and children/pets.

  • Toss and turn frequently during the night.

  • Need added protection for their new mattress.

  • Want to increase the lifespan of their current mattress.

Is a king mattress pad the same as a king mattress topper?

While they may serve a similar purpose, king mattress toppers and mattress pads aren't the same.

A king mattress pad is typically a thin layer/soft layer of material that sits on top of the mattress. King mattress pads usually work to provide cushioning and protection against spills.

On the other hand, king mattress toppers are thicker than king mattress pads, offering greater support and potentially extending the lifespan of your current mattress.

What are the common king mattress topper materials?

Latex, memory foam, gel memory foam, feather, and wool are some of the common mattress topper materials.

  • KING Latex Toppers

    Durable, flexible, breathable, and the most comfortable natural material to sleep on - latex mattress toppers are one of the best mattress toppers in the US.

    Latex toppers are known to provide great cushioning, contouring, and pressure point relief. Plus, they're bouncy and responsive, so you're offered more freedom of movement. The bounce also ensures you won't sink into the topper and risk spinal misalignment.

    While there are synthetic and blended latex options on the market, it's important to note that they are made with harsh chemicals that aren't safe for you or the environment. Stick with a natural latex topper for ultimate comfort and peace of mind.

    And don't worry about having to replace your natural latex topper every year - with proper care and maintenance, they can last for up to or more than 5 years!

  • KING Memory Foam Toppers

    Another classic option is a memory foam mattress topper, which conforms to the shape of your body for personalized comfort. The pressure-relieving material provides a great amount of cushioning and drastically reduces motion transfer, making it a pretty good choice for couples who want undisturbed sleep.

    If you're planning to buy one, make sure you go for a dense memory foam mattress topper, as the ones made with dense foam are much more durable and don't sag over time.

    But while they offer unparalleled comfort, it has been reported that traditional memory foam mattress toppers retain too much heat. There have even been recent concerns about potential toxicity in the materials used to make memory foam mattress toppers.

  • KING Gel Infused Memory Foam Toppers

    A gel memory foam mattress topper offers all the benefits of a traditional memory foam mattress topper - providing pressure point relief, cushioning, and motion isolation - with the added advantage of staying cool and being more responsive.

    They are usually made up of a combination of memory foam layers infused with cooling gel beads. The gel particles dispersed throughout the memory foam help regulate body temperature, alleviating heat buildup during sleep. The gel infusion also helps make the memory foam mattress topper bouncier.

    However, just like a traditional memory foam mattress topper, gel-infused memory foam mattress toppers are said to have a very strong odor upon unpacking due to the off-gassing of chemicals used in manufacturing.

  • KING Feather Toppers

    For those who prefer a more traditional feel, there's also down or feather fill, which adds softness and cushioning. These thick layers of feathers provide a soft cushion, trapping body heat to keep you warm at night. The feathers also distribute weight evenly, helping to eliminate pressure points.

    However, it is important to note that feather mattress toppers can be difficult to clean and may not offer enough support for those with back pain or health concerns.

  • KING Wool Toppers

    Filled with gentle natural fibers, wool toppers/mattress pads trap body heat to keep you warm at night without causing overheating. The material's remarkable moisture-resistant properties make it a hygienic option, helping to prevent sweat and stains on the underlying mattress.

    As a natural fiber, wool is usually considered safe, hypoallergenic, and dust-mite resistant for those with allergies or sensitive skin.

    One disadvantage of wool toppers/mattress pads is that the material has not proven to be as effective as foam alternatives in providing support or pressure relief. Therefore, in terms of the best option for those suffering from aches and pains, a wool topper/mattress pad may not be the one to consider.

Different mattress topper types to help you sleep

What is the difference between a king memory foam mattress and a king topper?

A memory foam mattress is a complete mattress made of two layers or three layers of memory foam, providing full-body support and comfort. A memory foam mattress topper is usually a thinner, single layer of memory foam designed to be placed on top of an existing mattress to enhance its comfort and support.

Is a king memory foam mattress topper better than a king latex mattress topper?

A traditional memory foam mattress topper is flawed in many ways when compared to a latex mattress topper. For instance, memory foam mattress toppers can retain body heat, off-gas VOCs, and sink you into them, offering less support. Natural latex mattress toppers can bypass these issues of a memory foam mattress topper by offering a breathable structure, eco-friendly materials, and a bouncy response.

So, if you prefer more cushioning than support and don't mind the drawbacks of a memory foam mattress topper, they're a good choice. But if you'd rather have more support, cooling, and eco-friendliness in your bed, a latex mattress topper is the best choice.

Mattress topper shopping for pillow top

What to look for when choosing the best king mattress topper?

Here are a few things that you must consider:

  • Size

    Before you buy a king topper, make sure the mattress you own is of the same size.

    In other words - Twin mattress toppers for twin beds, Twin XL mattress toppers for twin XL beds, Full mattress toppers for full beds, Queen mattress toppers for queen beds, King mattress toppers for king beds, and California king mattress toppers for California king beds.

    A topper that is too small may not provide even coverage, leading to discomfort and possibly impairing sleep. On the other hand, a topper that is too large can be difficult to maneuver on the bed and may lead to bunching and unevenness.

  • Material

    You get what you pay for - You might be tempted by that cheap foam model at the big store, but it may not provide the support and durability you need. Investing in a topper made of high-quality, durable materials can make all the difference in getting a good night's sleep.

    Materials like natural latex offer not only longer lifespans but also improved performance in categories like pressure point relief, temperature regulation, and motion absorption. Sure, they may come with a higher price tag, but when it comes to something as important as your sleep (and overall well-being), isn't it worth it?

  • Firmness level

    When shopping for a topper, firmness may not immediately come to mind as a primary consideration. But did you know that the level of firmness can have a significant impact on sleep quality and comfort?

    The firmness of a topper is often subjective, as it largely depends on individual preferences and sleeping positions - Well, what feels firm to one person may feel soft to another. That being said, the initial feel or "hand test" can still provide helpful information when trying out a new mattress topper.

    While some people may prefer the sinking feeling of a softer topper, others may desire more support from a firmer option. It's important for shoppers to keep in mind their sleep position, body weight, and any aches or pains they may have before making a decision on the firmness level.

    Generally speaking, those who weigh less than 130 pounds may prefer a softer topper that contours more closely to their body. In contrast, heavier individuals may benefit from a firmer topper that offers better support. Additionally, side sleepers tend to need softer materials for cushioning, while back and stomach sleepers often prefer firmer options. However, it's always a good idea to test out different levels of firmness in person before making a final decision.

  • Thickness

    You should also pay attention to the topper's thickness, as it can affect certain sleep factors like body pressure. A thicker topper can provide additional support and cushioning, while a thinner topper may not have as much impact on the feel of your bed.

    It's also important to take the overall height of your bed into account as well. A thick topper on an already high bed may make it more difficult for you to get in and out, while a thin topper might not provide enough support on very firm mattresses.

  • Heat retention

    Too much heat can disrupt sleep and leave you feeling uncomfortable, while not enough can make it difficult to stay warm at night. A good topper should offer some level of insulation, helping to maintain a consistent temperature during sleep.

    Many toppers are made from materials that tend to trap heat, resulting in an uncomfortable sleeping surface for hot sleepers. So, when selecting a mattress topper, be sure to carefully research materials and assess their ability to retain heat for a comfortable and restful night's sleep.

  • Mattress condition

    Looking for a quick fix for your sinking mattress? Sorry to burst your bubble, but a topper probably won't do the trick. Think of it this way: a played-out, lumpy mattress is like an old and crumbling cake. Sure, you could put the icing on top and make it look nice for a little while, but the broken-down foundation remains the same. The only real solution? Get yourself a new mattress.

  • Reviews

    Choosing the right topper can be difficult with so many brands and models on the market. You can get an idea of which king toppers are the best by reading reviews from other shoppers. You can also find out about potential problems that a particular model might have before you purchase it by reading reviews.

  • Warranty

    You'll want to ensure that your king-size topper is covered by a warranty. High-quality mattress toppers are generally backed by a 3-year warranty, although some brands offer 5-year warranties. You can have more confidence in the quality of the topper with a longer warranty.

  • Trial periods

    Most reputable retailers offer a trial period of at least 30 days, during which you can return the topper for a full refund if you are not satisfied. This gives you ample time to adjust to the new topper and decide whether it is comfortable and supportive enough for your needs.

What is the best king mattress topper for hot sleepers?

Based on our experience, the best king mattress topper for hot sleepers is one made of breathable materials like natural latex or wool. These materials will help regulate your body temperature during the night.

What is the best king mattress topper for back pain?

The best mattress topper for back pain is one that is thick and firm enough to provide a neutral spine alignment. But at the same time, it should also provide adequate cushioning and pressure point relief for optimal comfort.

Latex, egg crate, and memory foam toppers are often good options. However, it's important to keep in mind that memory foam is not natural, healthy, or eco-friendly like latex.

What is the best king mattress topper for hip pain?

The best mattress topper for hip pain is one that is firm and supportive. A latex mattress topper that is at least 3 inches thick is a good option, as it conforms to your body and provides excellent support, often required for relieving hip pain symptoms.

Egg crate, and memory foam toppers are also good options. However, it's important to keep in mind that memory foam is not natural, healthy, or eco-friendly like latex.

What is the best king mattress topper for shoulder pain?

The best mattress topper for shoulder pain is one with contoured surfaces that can cradle your shoulders and alleviate pressure points. When you are buying a topper specifically for shoulder pain, pay attention to the materials used.

Some materials, such as natural latex, are particularly good at molding to the body, providing targeted support and pressure point relief.

What is the best king mattress topper for heavy people?

If you're on the heavier side and looking for the best king-size topper, consider getting a thicker option. A thicker topper provides more support and cushioning. It also lasts longer since it is durable and doesn't sag much over time.

As far as materials go - natural latex and high-density memory foam are often good options for heavy people, as they contour the body and provide good support. If you are eco-conscious, health-conscious, or hate sleeping hot, avoid memory foam mattress toppers.

Heavy person sleeping

How long do mattress toppers last?

The lifespan of a mattress topper depends on its material, build quality, and use case. Generally, natural latex is the material that triumphs when it comes to durability, capable of offering 5+ years of resilient support. With proper care, most mattress toppers will last for 3 to 5 years or more.

Many toppers can be found with a three-year warranty. Based on our experience, we recommend looking for a topper with a three-year warranty or a five-year warranty, as the warranty length is an easy way to gauge the retailer's trust in their product.

What are the standard mattress topper sizes?

Here are some of the most common standard US mattress topper sizes.

  • Twin mattress topper

A twin-size topper is designed to fit a twin-size mattress. It typically measures 38 inches wide and 75 inches long, making it a good choice for children's beds or for use in small spaces.

  • Twin XL mattress topper

Measuring 38 inches wide and 80 inches long, a twin XL topper offers an extra 5 inches of length compared to a standard twin-size topper. Twin XL toppers are often used in college dorm rooms, as they can accommodate students of different heights.

  • Full mattress topper

Standard full-size toppers measure 54 inches wide and 75 inches long, making them a good fit for full-size mattresses. A full mattress topper is often the ideal choice for a single person who wants more sleeping space than a twin or twin XL.

  • Queen mattress topper

A queen-size mattress topper is 60 inches wide and 80 inches long. It is considered the most popular size topper sold in the United States. A queen-size topper can be considered the best option for two people who want more room than just what the full-size offers.

  • King mattress topper

A king-size mattress topper is one of the largest toppers available, measuring 76 inches wide and 80 inches long. King-size toppers are ideal for families who sleep together, couples who want space to move around, pet parents, and people who are taller than average.

  • California king mattress topper

The longest of the standard sizes, the California King mattress topper measures 72 inches wide and 84 inches long. It is ideal for families or couples who prefer more legroom than a regular king topper.

What are some important certifications to look for before buying a king latex mattress topper?

The best mattress toppers are often certified. For instance, the best memory foam mattress topper, gel-infused memory foam mattress topper, or other foam toppers are CertiPUR-US certified. Similarly, latex toppers also carry certifications.

Many latex toppers that are being sold today are either made of synthetic latex or blended latex. So look out for these certifications when you want the best, most natural king latex toppers -

  • GOTS (Global Organic Textile Standard)

GOTS, or Global Organic Textile Standard, is the textile processing standard that limits the use of bleaches, toxic dyes, and other chemicals during textile production.
