Sometimes the standard mattress sizes available from most retailers don’t meet your needs. Perhaps you have a sleeping space in your RV, camper, or boat that requires a special size mattress. Or you have a bedroom with an unusual shape. Or maybe you just want the flexibility to choose the materials that go into your mattress. In any of these scenarios, a custom mattress may be a good option.

There are different ways of creating a custom mattress, and the options available to you will depend on the manufacturer. Some companies provide a predetermined set of materials for the mattress cover, comfort system, and support core and let shoppers choose the specific dimensions. Other manufacturers allow a customized approach from start to finish.

We’ll review our top picks for the best custom mattresses, covering the selection of models available at each company and the array of customization options. We’ll also examine the nuts and bolts of custom mattresses, including the most common types, how much they cost, and bedding considerations.

The Sleep Doctor’s Review

Our testers appreciated the wide variety of custom mattress designs from Mattress Insider. Between the three all-foam models and one hybrid model, as well as five firmness levels, most of our testing team found a comfortable model. We also appreciated the cooling technology in the Elation, Luxury, and Scarsdale designs.

  • Choice of three custom foam mattresses and one hybrid model
  • Affordable pricing
  • Gel-infused foam in the Elation, Luxury, and Scarsdale models helps sleepers stay cool


  • Mattress Insider custom mattresses don’t come with a sleep trial
  • Many of the models may produce an off-gassing odor in the first few nights

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 Sleep Doctor’s Review

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.

  • Highly customizable dimensions
  • Custom corner cuts available for a notched, angled, or rounded design
  • Choice of three models, including a dual-zoned option with adjustable firmness on each side


  • Hot sleepers may overheat on the all-foam design
  • Couples who prefer a responsive surface for sex may find the mattress too plush

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.

  • Mattresses available in a variety of materials, thicknesses, and firmness levels

  • Custom cuts available for people with unique space considerations

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.

Why You Should Trust Us

Shopping for mattresses can be confusing when you’re looking for standard sizes, let alone custom creations. To help simplify matters, we’ve leveraged our years of experience in the sleep industry to personally research and test a wide variety of custom mattresses. Our team includes individuals with a range of body types and sleep position preferences so we can provide a well-rounded evaluation.

What Is a Custom Mattress?

Custom mattress is a broad term encompassing a range of mattress types. It applies to nonstandard mattress sizes designed for RVs, trucks, and boats, as well as mattresses built in specific sizes and shapes per the customer’s specifications.

Some companies offer standard sizes but let customers build their mattress from a set of options in a mix-and-match approach. However, the support core is often fixed in this scenario, especially for hybrid models.

Other manufacturers offer a predetermined set of materials in the comfort system and support core that can then be sized according to the measurements submitted by the customer.

Completely custom-built mattresses, where the customer submits specific measurements and selects everything from the cover fabric to the comfort system and support core materials, are less common and usually more expensive.  

Custom vs. Customizable

Many companies offer customizable mattresses that let buyers select from a variety of upgrades. These can include extra comfort layers or cooling features, different heights and firmness options, or optional toppers.

Custom mattresses can offer similar choices, but what distinguishes a truly custom model is the ability to request exact dimensions or shapes.

Types of Mattresses

While they may deviate from the standard sizes, custom mattress makers typically stick with common mattress types.

Mattress Type


Foam mattresses are made from polyurethane, a polymer known for its cushioning capabilities. Polyurethane foam, also known as polyfoam, can be produced in varying densities for use in both mattress comfort systems and support cores. Memory foam is created by mixing polyfoam with certain chemicals. The resulting viscoelastic material softens in response to heat and conforms to your body to provide strong pressure relief, making this type of mattress a good fit for side sleepers. However, memory foam mattresses tend to sleep warm. To offset this quality, companies often add cooling gels designed to draw away heat.


Hybrid mattresses have a comfort system consisting of one or more types of foam or latex over a core of pocketed coils. They combine the contouring comfort of foam with the support of an innerspring mattress for a best-of-both-worlds approach. Combination sleepers often benefit from the versatility of hybrid mattresses.


Traditional innerspring mattresses feature a support core of interconnected steel coils with a minimal layer of padding on top. This type of mattress is known for its bouncy feel, but it often transfers a significant amount of motion across the surface and lacks the contouring pressure relief required for most side sleepers. However, higher-end modern innersprings perform similarly to hybrids and sometimes feature a coil-on-coil design, with microcoils and other comfort layers resting atop a sturdy coil core. Back and stomach sleepers may benefit the most from the added support of an innerspring.


Natural latex is created from the sap of the rubber tree, though some mattress companies use synthetic or blended latex. Latex mattresses are typically bouncier and more responsive than memory foam models. Latex beds may appeal to sleepers who want pressure relief without the deep contouring of a foam mattress.

How Much Do Custom Mattresses Cost?

Custom mattresses often cost more than standard-sized mattresses due to the extra labor involved in their construction. However, costs can vary widely by manufacturer, and prices also depend on the quality of the materials and the size and shape of the mattress. It’s not uncommon for budget-priced custom beds to be significantly less expensive than high-end mattresses sold in standard sizes.

Custom mattress options where the shopper has carte blanche over the dimensions and materials will likely be much more expensive than mattresses with predetermined design options. 

Buying Bedding for a Custom Mattress

Custom beds may mean an investment in custom sheets. Certain standard-sized bedding pieces that hang over the edge of the bed, like duvets and comforters, can work for custom mattresses. In other cases — especially for mattresses made in special shapes — you will need to buy custom-made fitted sheets and other types of bedding.

Many custom mattress companies sell sheets to fit their beds. However, custom sheet makers generally offer a greater variety of materials and weaves, albeit at a greater cost to the consumer in many cases.

What Kinds of Custom Mattresses Are There?

There are many types of custom mattresses. Some are built to fit particular spaces. Others meet the specific needs of people looking for a combination of comfort, support, size, and shape.

RV and Camper

Recreational vehicle and camper owners often have specialized mattress needs. While some companies offer a standard set of RV mattress sizes — such as RV three-quarter, RV Olympic queen, and RV short king — older vehicles and those with unusual layouts may have unique dimensions that require shoppers to enter exact measurements for a quote. Many custom mattress makers have price calculators that make this a painless process.


Like RVs and campers, boats often have beds designed to make the most use of the available space, resulting in nonstandard dimensions. Boat owners may also require hinged mattresses that allow them to easily access storage compartments. 


A sofa bed involves a frame that’s pulled out of a couch after removing the cushions. While these mattresses offer a convenient and discreet sleep surface, sofa beds also often require nonstandard mattress sizes.

Sofa mattress sizes sometimes correspond with RV mattress sizing. However, exact measurements may vary by manufacturer, so be sure to measure your sofa bed before ordering.


The largest standard mattress sizes are the king and the California king. Oversized mattresses, like the Texas king and Alaskan king, have standardized dimensions but are not widely available. While some online mattress companies offer these larger sizes, they are uncommon among the most popular brands.


Unconventional mattresses include shapes like circles, half moons, and hearts. These mattresses may require a completely custom build. 

Should You Buy a Custom Mattress?

Custom mattresses let you personalize your sleep experience by selecting the combination of layers and materials that best meets your specific needs. Custom mattresses can also provide the flexibility in size and shape to fit unusual spaces without sacrificing quality or comfort.
