Mattress Insider’s lineup includes four models available in custom dimensions spanning 28 to 80 inches in width and 29 to 80 inches in length.
Why We Like It
The Sedona is the company’s most affordable option. It features an organic cotton cover and 5.5 inches of proprietary foam with a high-density composition. Our testing team gave it a firm (8) rating on our 10-point firmness scale. We also noticed that its low profile and one-layer design lacks the cushioning needed for side sleepers and the support required for stomach sleepers. However, our back sleepers under 130 pounds felt adequately supported.
A more versatile option is the 6-inch Elation model. It’s a flippable mattress, giving sleepers the option of a medium (5) or medium firm (6) feel. The softer side has a 1-inch comfort layer of gel-infused memory foam and another 1.5 inches of proprietary foam designed for better breathability. The 3.5-inch support core of higher-density foam becomes the firmer side’s comfort layer when flipped.With a choice of four models ranging from medium soft to firm, Mattress Insider offers an impressive array of custom mattress solutions, including a hybrid option for sleepers who prefer a coiled support core.
How Does It Feel?
During our sleep lab tests, the soft side earned an excellent rating from side sleepers under 130 pounds. Back sleepers between 130 and 230 pounds preferred the firm side, while the two sides received comparable ratings from other testers.
The Luxury is Mattress Insider’s high-end foam model. It comes in two heights, 8 inches and 11.5 inches, both of which are flippable for adjustable firmness. The softer side of the 8-inch version has two layers of gel-infused memory foam totaling 3 inches, plus 5 inches of firmer foams for a medium (5) feel. The other side reverses the layers, giving the mattress a firm (7) feel.
The 11.5-inch version doubles the height of the support foam to 7 inches. The softer side of the higher-profile Luxury has a firmness rating of medium soft (4), while the firmer side is a firm (7).
Our testers found that the soft sides of both Luxury options worked best for sleepers under 130 pounds. The soft sides also earned above-average marks from side and back sleepers weighing between 130 and 230 pounds. The firmer side of the 11-inch mattress slightly outperformed the 8-inch version among most testers, especially back sleepers over 130 pounds and side sleepers over 230 pounds.
Lastly, there’s the Scarsdale, a 9-inch hybrid mattress with a medium firm (6) feel. The mattress uses a layer of gel-infused memory foam on top of pocketed coils for a combination of support and comfort. The side and back sleepers on our testing team who weigh between 130 and 230 pounds gave this mattress excellent ratings.
The Tochta offers customers three different designs in custom sizes and profiles at a competitive price-point. Our testers particularly enjoyed the Divini model’s adjustable firmness and dual-zone construction, which should ensure a comfortable surface for most sleepers who enjoy foam models.

Tochta offers three types of mattresses available in custom sizes and thicknesses. Customers can select from standard sizes or request specific shapes at factory-direct prices.
Why We Like It
Featuring granular levels of customization and a split comfort option for couples and co-sleepers, Tochta’s three custom models provide a level of personalization typically seen in mattresses that carry much higher price-points. During our hands-on tests, all three models were whisper-quiet and earned very good ratings for pressure relief and motion isolation.
How Does It Feel?
The Journey is the company’s most affordable mattress. It features a gel-infused memory foam comfort layer over a support core of high-density foam. We found that the side sleepers on our testing team who weighed more than 130 pounds appreciated its contouring capability and pressure relief. Back sleepers between 130 and 230 pounds and stomach sleepers under 130 pounds reported that the medium firm (6) option gave them the best support.
Tochta’s most popular mattress is the Utopia, which has a comfort layer made of dual phase change foam designed for cooling and contouring. The soft (3) feel was a good fit for our testers weighing less than 130 pounds and for our side sleepers between 130 and 230 pounds. However, heavier individuals, especially back or stomach sleepers, may not get enough support from the Utopia.
The Divini offers an even more personalized experience with nine possible firmness levels for each side of the mattress. These firmness options are created by using two layers of foam that are either soft, medium, or firm. For example, a medium layer followed by a firm layer creates a medium firm feel, while a medium layer on top of a soft layer results in a medium soft feel. You can adjust the firmness level by unzipping the cover and rearranging the foam layers. If needed, Tochta will ship additional foam densities to you free of charge.
Custom Mattress Makers offers custom mattresses in several designs, profiles, and firmnesses that ensured a comfortable option for most of our testers. Fully customizable sizing and options to add angle corners should also appeal to RV owners and people with other uniquely sized sleep spaces.

With more than a dozen all-foam, latex, and hybrid models of varying heights to choose from, Custom Mattress Makers lets shoppers customize the length and width of their mattress. Each of the designs can be built with measurements ranging anywhere from 25 to 78 inches in width and 50 to 84 inches in length.
Standard mattresses range in height from 6 to 13 inches, and may feature all-foam, hybrid, latex, or coil-on-coil innerspring designs. The low-profile models are part of the Largo and Cape product lines. Available in foam and latex designs with profiles of 6 or 8 inches, these are the most affordable options. You can also choose a 5-inch Cape sofa bed.
Why We Like It
Custom Mattress Makers lets customers add an additional level of customization with special cuts to the corners of the mattress for an angled, notched, or rounded design. Angled and rounded cuts can help RV owners squeeze mattresses into corner spaces, while notches can accommodate oversized bed posts.
The company notes that its mattresses may have as much as a 1-inch variance in each direction on custom hybrid mattress orders due to the diameter of the coils. With foam, latex, and hybrid models in varying firmness levels that are made to order in your desired dimensions, Custom Mattress Makers has a mattress solution for nearly any setup.
How Does It Feel?
Thicker mattresses in the Cape, Largo, Daytona, Clearwater, and Ozona lines are built with materials such as gel-infused memory foam, responsive Talalay latex, and dual-layer coil systems. Most have a medium firm (6) or firm (7) feel. These models earned excellent marks from side sleepers weighing more than 130 pounds, back sleepers under 230 pounds, and stomach sleepers under 130 pounds. The Luxury Plush Cocoa, which rates a 3 out of 10, received the highest praise from side sleepers on our testing team who weigh less than 130 pounds. In general, Custom Mattress Makers’ beds earned above-average marks from our testing team for temperature control and ease of movement. Mattresses with medium and soft firmness levels rated highest in pressure relief and motion isolation, while the firmer models tended to have stronger edge support.
A custom mattress is a mattress that can be personalized according to the buyer’s preference. Custom mattress manufacturers generally allow shoppers to pick from several templates and make certain modifications to the size, shape, and firmness.
Some luxury companies offer the chance to design the bed from start to finish. These beds tend to retail in the tens of thousands of dollars.
Standard mattress companies may offer select customization options, such as different firmness levels or enhanced cooling upgrades. But unless the buyer also has the ability to design their own size and shape, these mattresses are considered “customizable” rather than truly custom models.
Where Can You Buy a Custom Mattress?
Custom mattresses must generally be ordered directly from the manufacturer. The easiest and most cost-effective way to do this is online. You may also be able to work with a brick-and-mortar store to help you design your mattress.
While there are hundreds of mattress companies, just a handful offer custom mattresses. However, some mattress manufacturers may offer their mattresses in a selection of non-standard sizes, such as RV sizes.
Who Should Consider a Custom Mattress?
Custom mattresses can often be designed down to the exact inch, including the ability to add hinges or choose a unique shape. This high level of personalization makes custom mattresses a good solution for RVs, boats, and other unorthodox spaces.
There’s more cost and effort required to produce a custom-made mattress, so the average price runs a little higher than an off-the-shelf mattress, but many companies offer competitive prices for their custom beds.
Pros
Can be designed to fit a unique space, like RVs and boats, or shapes, like a heart or circle
Materials and firmness can often be personalized as well
Cons
Orders are more complex and take longer to prepare
May be more costly than a standard mattress
May not include a sleep trial
Harder to source bedding to fit
What to Look for in a Custom Mattress
Along with the size and shape, factors to look for when purchasing a custom mattress include material quality, comfort, and the additional costs that can be involved.
Mattress Size and Shape
Perhaps the greatest advantage of a custom mattress is being able to create a bed that is the exact size you need. Some of the most common non-standard mattress sizes are the Alaskan king, the Texan king, or the Wyoming king. These oversized beds may appeal to people who like a larger sleep surface or those who sleep with the entire family.
The ability to custom design a mattress can be particularly convenient for spaces with height limitations or unique shapes.
RV: While the more common RV mattress sizes such as short queen or short king may be stocked by regular manufacturers, some vehicles may require a custom fit.
Boat: A mattress for your boat may or may not fall into a standard size, and certain beds include hinges so that you can lay it over a storage compartment.
Sofa: While many sofa beds use standard mattress sizes, some may require a custom model. Look for a thin mattress that can handle being repeatedly folded and unfolded if necessary.
Unconventional: Custom mattresses can be designed in exclusive shapes such as a heart or a circle, or a non-standard rectangular variation for an antique or international bed frame.
Mattress Material
Custom size mattresses are available in most of the common mattress types, including foam, hybrid, and latex. Latex and polyfoam models tend to offer the most flexibility in terms of shape, as the foam can be easily cut without affecting the structural integrity. Making a custom shape hybrid or innerspring mattress may require a little more planning in order to arrange the coils, but many companies offer this option as well.
Support
Support refers to a mattress’ ability to promote healthy posture. Robust materials such as coils, latex, or high-density foam in the support core can prevent heavier parts of the body from sinking in too far and pulling the spine out of alignment.
A mattress’ firmness is also key, and it’s important to consider your sleeping position and body weight when determining the appropriate level. A mattress that’s too firm may cause uncomfortable pressure points, whereas a mattress that’s too soft may allow excessive sinkage.
Durability
Since a custom mattress is harder to replace, it’s worth purchasing a model made with durable, high-quality materials. Mattresses made with denser foams, higher coil counts, and natural materials are likely to have a longer lifespan.
Pricing
Pricing for custom mattresses varies widely according to the exact size, thickness, materials, and any special requests. You should also factor in the additional costs of customized bedding and frames, as well as potential shipping, delivery, and setup costs.

Frequently Asked Questions
Who should buy a custom mattress?
You may benefit from a custom mattress if you’re working with an atypical bed frame, such as one in a boat or an RV, or if you have specific ideas about what you want in a mattress and you’re unable to find one that fits your needs.
What is the difference between a custom and customizable mattress?
A customizable mattress may allow shoppers to choose between several preset options, such as different firmness levels. By contrast, a custom mattress is one that’s made from scratch and sized precisely according to the customer’s requirements.
How much does it cost to build a custom bed?
While custom beds start around $500 for a very thin, basic model, you can usually expect to pay upwards of $1,000. The price can vary according to the size, brand, material quality, and specific shape requirements.
What kinds of custom mattresses are available?
Common options for custom mattresses include foam, latex, and hybrid models. For a higher price, you can also find custom mattresses made with silk, wool, horsehair, or other premium materials. When in doubt or if you’re looking for inspiration, don’t be afraid to ask the manufacturer for advice.
Where can you buy bedding for a custom mattress?
Custom-sized bedding is available online from select manufacturers, and you may be able to source custom bedding from the same company that sells you the mattress. Standard-sized bedding may fit over custom models that are similar to a standard size, although it might not fit perfectly.
Do custom mattresses come with a sleep trial and warranty?
Custom mattresses may or may not come with a sleep trial as mattress companies are usually less willing to provide a refund for non-standard mattresses.
Most custom beds do come with a warranty to protect against manufacturing and workmanship defects. While standard mattress warranties tend to be upwards of 10 years, a custom mattress warranty may be shorter, particularly for thinner models.
