        A Complete Look at Turmerry Latex King Mattress and Its Many Benefits

        You've been acquainted with the highlights of our latex beds, but you have yet to find out their true potential! Here are all the benefits you'll get when sleeping on one of our king-sized beds:

        • Healthy support and pressure relief

          Our all-foam mattress types are made with Dunlop latex foam layers, while our spring-type mattresses are made with Talalay latex and pocketed coils. Dunlop latex provides greater firmness, support, and density than Talalay latex, which veers more towards cushioning and pressure relief. Moreover, the pocketed coils provide targeted support to each and every part of your body.

        • Bouncy response

          Latex is essentially rubber at its core, which gives it a buoyant feel. This bounce is crucial if you're a light sleeper, as it doesn't inhibit movement atop the mattress. Latex is also highly responsive to your movements. The responsive latex makes sure you get the necessary comfort and support no matter where you lie on the mattress.

        • Long lasting resilience

          Latex has a strong internal structure that makes it highly resilient to wear and tear over time. When cared for properly, latex beds can provide a sag-free experience that lasts around 15-20 years! This is further ensured by the quality materials and construction we use to manufacture our mattresses.

        • Perforated cooling

          Hot sleepers and heavier sleepers will love the carefully perforated surfaces of our beds, which allow unrestricted airflow through them. This ensures that our mattresses don't trap heat but instead provide a cool environment when falling asleep!

        • Strong edge support, motion isolation, and noiselessness

          Three factors are essential for any restless or light sleeper, and we've got them covered in each mattress! Natural latex has a resilient structure that ensures a reinforced perimeter and firm support at the edges. Latex foam also absorbs and isolates motion very well, as do pocket coils. To top it all off, you won't encounter any sleep-disrupting squeaks or creaks from our beds.

        • Eco-friendly goodness

          We've amassed certifications from GOLS, GOTS, OEKO-TEX, and eco-INSTITUT, which inspect the level of inorganic substances used in our mattresses and deem them safe for human health. When you value the overall health of you and your loved ones, an organic mattress such as ours is always the right choice to make.

        King-Size Mattress - Buyer's Guide

        What is a king-size mattress?

        King-size mattresses are larger than most other standard mattress sizes and have a dimension of 76" x 80". They're often chosen for two or more people who need a lot of sleeping space.

        Note: The recommended bedroom space for a king mattress is 12 by 12 square feet or more. If your bedroom is smaller, a king mattress may end up cramping the whole place.

        Is a king-size mattress better than other mattress sizes?

        • Against Twin, Twin XL, and Full-size mattresses

          Speaking in terms of the space provided and the number of people that can be accommodated, king-size beds are far superior to twin (38" x 75"), twin XL (38" x 80"), and full-size (54" x 75") beds. King-size beds can also accommodate tall sleepers above 6 feet, similar to how a twin XL can.

          But when it comes to affordability and the space required, king beds do not fare well against these mattress sizes. King mattresses are priced on the higher end, and they also require quite a lot of bedroom space to ensure they aren't cramped.

        • Against Queen mattresses

          Queen mattresses (60" x 80") share the same length as king mattresses but are narrower by 16 inches. This makes them budget-friendly for couples, single parents, pet owners, and those who don't need space for more than two people. King mattresses, although costlier, provide a much wider space for couples and families to sleep in.

        • Against California king mattresses

          A California king mattress (72" x 84") is 4 inches narrower than a regular king mattress but compensates for it by being 4 inches longer. This extra length offered by cal king beds provides much better legroom for tall people (above 6 feet).

          California king and standard king mattress sizes are usually priced the same by most mattress retailers. And even though a California king bed is narrower, it can still comfortably fit a family of three.

        Does a king mattress size suit you?

        With all its spaciousness, does the king-size mattress actually suit your nightly needs? Find out whether king mattresses suit you or not:

        King-size mattresses are suitable for -

        • Singles, Couples, and Families: King-size mattresses can easily hold up to a family of four. This makes it much more spacious for couples and single sleepers as well. If you're someone who prefers having a lot of sleeping space to yourself, be it due to just general comfort or health issues, a king bed may be the ideal route for you.

        • Larger Sleepers, Restless Sleepers, and Combination Sleepers: Thicker couples who weigh over 230 lbs., restless sleepers who move around constantly, and combination sleepers who don't have any preferred sleeping position may desire more space than what a queen bed can provide. A king bed is, therefore, ideal for their needs.

        • Huge Bedrooms/Guest Rooms: Trying to place a smaller mattress size, such as twin, twin XL, or full, into a very large bedroom/guest room may mess with the overall aesthetic. Moreover, a lot of room may end up being wasted. A king bed is best fitted for master bedrooms, master suites, luxurious vacation rentals, hotel suites, etc.

        King-size mattresses aren't suitable for -

        • Sleepers on a Budget: Buying a king mattress is a costly endeavor. A quality one, on average, can cost you anywhere from $1500-$3000. If you're looking to sleep alone, a twin, twin XL, or full-size mattress would be the budget-friendly option. And if you're sleeping with a partner, we'd suggest a queen-size mattress.

        • Smaller Rooms/Apartments: Placing a king bed in compact spaces can make the room feel cramped and hinder functionality. Generally, rooms that are smaller than 12 x 12 sq. feet, when fitted with a king bed, do not leave much room for walking or storing furniture. The same goes for smaller apartments, like studio apartments and one-bedroom apartments.

        • Mobility or Accessibility Concerns: King-size mattresses can be heavy and challenging to move. If you anticipate needing to move your mattress frequently due to mobility issues or accessibility concerns, a smaller mattress size may be more manageable.

        What are the different types of king-size mattresses?

        There are several different types of king-size mattresses available today that cater to various sleeper preferences. Here is an overview of the most commonly available mattress types:

        1. Innerspring Mattress

          Spring coils serve as the primary support system in innerspring mattresses. And for added comfort, they usually have a thin layer of foam or padding. Good support, breathability, and bounce go hand in hand with the traditional firm feel of innerspring mattresses.

        2. Memory Foam Mattress

          Memory foam mattresses are made with low-density/high-density memory foam that conforms to the body's shape, providing excellent pressure relief and motion isolation. They can alleviate pain, especially for individuals with joint or back issues. It is also possible to find memory foam mattresses with gel-infused foams. Gel-infused memory foam beds have enhanced bounce and cooling properties.

        3. Latex Mattress

          Mattresses made from latex foam can be natural, blended, or synthetic. Natural latex is the best of them all, providing a responsive and bouncy surface that supports well. Natural latex mattresses are also well-known for their durability, breathability, motion isolation, edge support, and eco-friendliness. They offer a balance of support and comfort.

        4. Hybrid Mattress

          A hybrid mattress combines the support of modern spring coils with the comfort of memory foam or latex layers. Hybrid beds are designed to offer the advantages of various materials, including improved support, pressure relief, and temperature regulation. For those who desire a balance between support and contouring comfort, hybrid mattresses are appropriate.

        5. Air Mattress

          Airbeds have customizable air chambers that act as the support core and let you adjust the firmness to your preferred level. They can be inflated automatically through automatic pumps and remotes or manually through manual pumps. Airbeds are suitable for individuals who prefer a temporary, portable mattress with customizable firmness and support.

        What is the best king mattress type?

        Having considered what each mattress type offers in the above section, we would recommend natural latex mattresses as the best king mattresses.

        • Natural latex is eco-friendly

          The outstanding benefit of opting for a natural latex mattress is the eco-friendly, healthy surface you get to sleep on. Natural latex beds purchased from a reputable retailer are made of natural mattress materials and do not emit hazardous levels of chemical compounds.

          Traditional memory foam, gel-infused memory foam, polyfoam, and other beds made from synthetic materials are frequently laden with chemicals. This can lead to long-term, if not immediate, health issues for you and your loved ones.

        • Natural latex is responsive, comforting, and supportive

          A natural latex mattress is both comfortable and supportive. They can relieve pressure through even body weight distribution and exquisite body contouring. Furthermore, their luxury firm foam design provides firm support for the spine while also ensuring a long mattress lifespan.

          As latex is rubber, it will be naturally bouncy and responsive. Unlike memory foam, you will not be sucked into a latex mattress. Instead, your movement atop the mattress will be unhindered, and each part of your body will be given the comfort it desires.

        • Natural latex also possesses other benefits

          To add to the benefits mentioned above, latex is highly breathable due to its open-cell structure, making it the best mattress for hot sleepers. Latex can also provide sufficient motion isolation, noiselessness, and edge support to ensure your sleep is undisturbed.

        How much does a king-size mattress cost?

        On average, a good king-size mattress will cost you between $1500-$3000. This range accounts for a variety of factors, including the quality of materials, construction, brand reputation, and additional features.

        When seeking out the best king-size mattresses, you'll find yourself having to pay on the higher end ($2000-$3000). These mattresses will be made with high-quality materials, durable construction, and well-known brands.

        Medium-quality king beds can be priced somewhere around ($1300-$1900). They are significantly less expensive and do not lag far behind higher-quality beds in terms of quality and benefits.

        Low-quality king beds usually start at around $800-$900. The materials and construction used in the making of these beds will be of much lower quality in contrast to mid or high-quality king beds. They may also be deficient in terms of quality and benefits such as cooling, durability, motion isolation, edge support, and so on.

        Unless you have a tight budget and are willing to take a chance on lower-end king beds, we recommend going with a medium or high-quality one. A higher-quality bed may cost less if you purchase it through the proper channel. We'll discuss that in the next section.

        Should you buy your king mattress online or in-store?

        Buying online and in-store both have their own set of pros and cons.

        Buying online

        • [Pro] Online shopping enables you to browse and buy from the convenience of your home, eliminating the need to visit a physical store.

        • [Pro] Online shopping provides a wider variety of options, including various brands, models, and price points, giving you more options to find the ideal mattress.

        • [Pro] Online retailers tend to have competitive prices due to lower overhead costs, allowing you to find better deals and discounts.

        • [Pro] Online platforms provide access to mattress reviews and ratings, offering insights into the experiences of other buyers.

        • [Con] When buying online, you can't physically test the mattress before making a purchase. Relying solely on product descriptions and reviews may not provide the same level of certainty.

        • [Con] Returning/exchanging a mattress bought online can be more cumbersome compared to in-store purchases. It may involve arranging for pickup or shipping and can be subject to specific return policies, fees, etc.

        Buying in-store

        • [Pro] Shopping in-store allows you to physically test out different mattresses to assess their comfort, support, and overall feel.

        • [Pro] To help you make an informed choice, retail staff can make personalized recommendations based on your unique needs.

        • [Pro] In-store purchases allow you to take the mattress home right away without waiting for delivery.

        • [Con] Physical stores may have a more limited selection compared to online retailers, potentially limiting your options.

        • [Con] In-store prices can be higher due to additional costs associated with keeping a storefront open.

        • [Con] Shopping in-store requires traveling, dedicating time to visit different stores, and dealing with potential crowds or limited operating hours.

        In the end, the choice is yours. Our advice is to try out mattresses in-store before purchasing the one you like online. This way, you can try out mattresses before purchasing them while also reaping the benefits of online shopping.

        What essential features should you consider having in your king-size mattress?

        The presence of certain features in your mattress can make it a much more pleasant surface to sleep on. Find out what these features are:

        • Sleeping style accommodation

          Whether you're a side sleeper, back sleeper, stomach sleeper, or combination sleeper, the mattress you choose must provide sufficient accommodation. This includes providing your spine with a healthy amount of support and your body with exquisite contouring that relieves pressure points.

          Generally, side sleepers are recommended a medium-soft/medium-firm mattress, as it can support the spine's alignment without putting too much pressure on the sides. Back and stomach sleepers are recommended to have a firmer mattress for additional spine support.

        • Body weight and height support

          Consider your body weight primarily when finalizing a mattress purchase. Heavier individuals require a thicker, firmer, and denser mattress. This is to ensure they don't sink into the mattress and risk a case of spinal misalignment.

          Conversely, lightweight and average-weight individuals require a mattress with soft or medium firmness, thickness, and foam density. Body height is also a consideration to keep in mind. Fortunately, king-size mattresses can comfortably accommodate sleepers as tall as 6'6".

        • Motion isolation

          If you sleep with a partner, motion isolation is important to minimize disturbances from their movements. All-foam mattresses are better at providing this feature than spring mattresses. The foam layers absorb motion much more effectively than spring coils, allowing you to enjoy uninterrupted sleep.

        • Edge support

          When a mattress feels slightly softer at its edges, and you find yourself slipping off the edges often, this is an indicator of a mattress without proper edge support. In a nutshell, edge support is the resilient pushback provided by the perimeters of a mattress when sitting or sleeping on it.

          Reliable edge support is essential for maximizing the usable surface area of the mattress and providing stability at the bed's edges. Latex and hybrid mattresses are our recommended choices if you seek this feature.

        • Durability

          A durable mattress is a worthwhile, long-term investment. The durability of a mattress is primarily determined by its materials and construction. For example, natural latex is a highly sturdy material that can last up to 20 years with the right care. Another example is a hybrid mattress, which usually employs quality materials and solid construction.

        • Cooling and breathability

          Breathable mattresses permit unrestricted airflow through them. This keeps hot sleepers cool throughout the night and wicks away moisture to prevent allergen buildup. Breathable mattresses can be a necessity, especially when you live in a warm climate. Sleeping hot may even cause disturbances in your sleep.

          You can find a cooling, breathable mattress by choosing the right material and construction. Natural latex and gel memory foam are highly cooling materials, while traditional memory foam isn't. Construction-wise, you'll find spring mattresses to be better at promoting airflow than all-foam mattresses.

        • Customizability

          Mattress retailers usually allow you to customize the thickness and firmness levels of a king bed. These two aspects of a mattress can significantly affect its adaptability to different body types and sleeping positions.

          Other customizable aspects can include the addition of a mattress protector cover, pillow top, euro pillow top, zoned support, etc.

          When deciding upon your mattress height (thickness), make sure you factor in the overall bed height as well. Choosing the wrong bed height can end up negatively affecting your bedroom aesthetic, bed mobility, and storage space!

        • Warranty and trial period

          Always, always, always read the fine print on the retailer's website regarding the warranty, return policies, and trial period. A mattress warranty keeps your mattress insured in case of any defects or damage. Look for warranties that provide coverage for a significant duration, typically over 3 years, and encompass various aspects related to the mattress' performance.

          Trial periods let you test out the mattress in your home before you finalize your purchase. They can last anywhere from a month to an entire year! If you have concerns about purchasing the wrong type of mattress, a trial period offers the flexibility to return or exchange it within the specified timeframe.

          And don't forget to familiarize yourself with the retailer's return policy, as it outlines the requirements for returning or exchanging a mattress. Pay attention to details such as the timeframe for returns, any restocking fees, and the condition the mattress must be in for a valid return.

        What is the ideal bedding to pair with a king-size mattress?

        Purchasing a new mattress feels great, but you're only halfway to the ultimate goal of a comfortable bed. Bedding and other accessories ensure that your mattress provides the best possible sleep experience.

        One of the essential elements to consider is the bed frame. A sturdy bed frame provides proper support for your king-size mattress. Look for a frame that matches the size and style of your mattress, ensuring it has strong support beams and a solid foundation to prevent sagging.

        Up next are pillows, which play a vital role in enhancing neck and head comfort. Choose pillows that suit your preferred sleeping positions. For instance, side sleepers may benefit from firmer, higher loft pillows, while back or stomach sleepers may prefer medium to low loft pillows.

        Mattress toppers and protector covers are also popular bedding options to pair with a king-size mattress. Toppers have the ability to change how the mattress generally feels, making it softer or firmer. Toppers can also reduce the amount of wear and tear on the mattress's surface. Mattress protector covers repel outside impurities such as dust, dirt, and allergens.

        Then there are the less popular but equally essential bedding items, such as bed sheets, blankets, comforters, duvets, etc., that help you make your bed as cozy as possible!
