Despite usually being a step up from an air mattress, traditional sofa bed mattresses have a bad reputation for being uncomfortable, but these mattresses have come a long way from the days of feeling too thin or too firm and offering unbalanced support. Similar to a futon mattress, a space-saving sofa bed turns an ordinary couch into a guest bedroom with a bit of unfolding.

Finding the right sofa bed mattress depends on the mattress type, proper fit, and the right amount of comfort. When these features align, the bed turns any space into a welcome place for guests.

Best Coil

Leggett u0026 Platt AirDream Inflatable Mattress

See It

A critique of traditional coil sofa bed mattresses is that they’re not as plush as other types. This sofa bed mattress from Leggett & Platt uses the support from innerspring coils with patented air-over-coil technology for abundant softness. The steel coil system gives sleepers the firm support and stability they expect from an innerspring mattress, but this one provides similar comfort to a regular bed with an air bladder layer and padded cover.

An included, simple-to-use electric pump fills the comfort layer with air quickly; it takes less than a minute to fully set up, as long as the sofa is near a wall outlet. If the mattress is too firm, the button on the valve cap releases air to customize the firmness level to increase softness. Whereas usual sofa mattresses are between 4 and 5 inches thick, this mattress inflates to an 11-inch depth. Deflated, the mattress is less than 5 inches thick, making it easy to fold back into the sofa. This hypoallergenic mattress fits most sleeper sofas and comes in full and queen sizes.

Product Specs 

  • Material: Metal and fabric
  • Thickness: 11 inches
  • Mattress size: Queen or full


  • The hypoallergenic materials help provide sensitive sleepers with untroubled rest
  • Soft surface covers a firm and supportive air over innerspring design
  • Includes hand-held electric pump for easy inflation in under a minute
  • Once deflated, it folds easily back into most sleeper sofas


  • Leaks can be an issue with all air mattresses, although complaints are not common

PlushBeds Sofa Bed Memory

PlushBeds Sofa Bed Memory Foam Mattress

See It

Like most memory-foam sofa bed mattresses, the PlushBeds version is made from two layers. The key difference here is in the density of the foam. Cheap mattresses often compress too much, and the sofa’s slats or frame can be felt so they disturb sleep. The higher quality materials in the PlushBeds model offer full support so that doesn’t happen. An additional benefit is the even distribution of body weight eliminates pressure points.

Mattress construction satisfies the independent testing standards of both CertiPUR-US and GreenGuard Gold which regulate emissions and prevent the use of hazardous chemicals or materials.

The PlushBeds memory-foam mattress is hypoallergenic and has a fire-resistant layer made from natural plant fibers rather than the usual fiberglass which can irritate airways. The open cell structure draws heat away so sleepers can retain their naturalbody temperature. The cover is luxurious cotton.

Product Specs 

  • Material: Memory foam
  • Thickness: 4.5 inches
  • Mattress size: Single, twin, twin wide, full, full wide, queen, queen wide


  • Uses proprietary foam combination to relieve pressure points and maximize comfort
  • U.S. manufacture meets the independent CertiPUR-US and GreenGuard Gold standards
  • Available in an extensive range of sizes to fit virtually any sofa bed


  • This mattress comes with a significantly higher sticker price than many competitors

Best Latex

PlushBeds Latex Sofa Bed Mattress

Latex is often seen as the pinnacle of sofa mattress luxury, but many manufacturers use synthetic latex or add fillers. These reduce the support provided, and shorten lifespan. PlushBeds use 100 percent natural latex formed using the Talalay method. This results in superior buoyancy that relieves pressure points, and increases all-around comfort.

A soy-based PlushFoam base layer ensures support for adults of up to 250 pounds and prevents discomfort from the metal structure of the sofa bed. Ventilation holes within the mattress help cool the body for undisturbed sleep. Durability is excellent, and PlushBeds claims its latex sofa mattress will never sag, break down, or lose its original shape.

Made in the U.S., the mattress is hypoallergenic and certified by CertiPUR-US and GreenGuard Gold for low emissions and an absence of hazardous chemicals and materials. The organic cotton cover is certified by Global Organic Textile Standard (GOTS).

Product Specs 

  • Material: Latex

What to Consider When Choosing a Sofa Bed Mattress

Each sleeper has individual preferences and needs in a mattress. Finding the best sofa bed mattress that’s comfortable for a variety of future overnight guests can be tricky. The best sofa bed mattress is cozy for most people, fits the sofa properly, and offers buyers a trial period to try it out at home before deciding whether to keep it.

Types of Sofa Bed Mattresses

Sofa bed mattresses come in numerous designs, materials, and sizes. The sofa bed mattress selected depends on personal preference, budget, and the pros and cons of each material. These factors help determine which type of sofa bed mattress is best for individual homes.

Memory Foam

Memory foam creates a plush sleeping surface to boost the comfort of a sofa bed mattress. The foam molds around the body, contouring to the sleeper’s unique shape. Very few mattresses are made entirely of memory foam; most memory-foam sofa bed mattresses come with a top layer of memory foam on a supportive base layer of denser foam, such as polyfoam.

When multiple layers are used, they are laminated together, keeping the mattress in one solid piece rather than separate layers that slide against each other. The base foam in these mattresses usually performs better when it is at least 2 inches thick, since denser foam offers more supportive sleep.

Gel-infused memory foam contours around sleepers the same way as standard memory foam. This style integrates gel into the memory foam to help generate coolness in the mattress. Gel conducts warm air away from sleepers so they don’t overheat.


Coil mattresses used to be the standard with sofa beds, but they are becoming less common. The perks of coil mattresses are affordability and airflow. These mattresses usually feel quite firm, which can benefit some people with back pain. Using a coil mattress with many springs offers more support for overnight guests.

The springs compress with pressure and revert to their neutral position when a person gets out of bed. Since most sofa bed mattresses are only a few inches thick, coils have limited space to compress and spring back. Plus, the comfort layer above the coils is generally thinner than the comfort layer on other types of mattresses.

Coil mattresses provide adequate support for some, but many sleepers require more comfort. Due to the thinness of the sofa bed mattress, innerspring mattresses are less comfortable for side sleepers and those with pressure-point pain. High-quality mattresses seldom use coil technology unless they are a hybrid mattress type.


For a quiet and cozy mattress, a foam sofa bed mattress replacement might be the way to go. Polyfoam is a popular type of foam mattress that serves as the base layer for many foam and memory-foam mattresses. Polyfoam offers thick, sufficient support and helps relieve pressure when guests lie down on the mattress.

Comfort layers for foam mattresses are made of additional polyfoam, or cotton, wool, polyester, and more. The foam absorbs motion from a partner’s movement through the night, keeping sleepers from waking each other up. One drawback of foam is heat retention, as some foams can trap warm air and may cause sleepers to overheat.

Due to the softer nature of foam, some sleepers might feel the sofa bed support bar under the mattress; this can be avoided by using a high-density foam with more pounds of material per cubic foot. For the best quality foam mattress, find a material that has a support base with a foam density between 1.8 and 2.5 pounds per cubic foot.


Made from natural foam rubber, latex is a healthy choice for sofa bed mattresses and offers great durability, body contouring, and support. Tru-latex (or all-latex) mattresses are constructed entirely of latex, making them high quality, but more expensive.

A latex core and comfort layer gives an exceptional sleep surface that supports and contours the body. Similar to memory foam, latex moves with the weight of the sleeper, for spinal alignment and pressure relief, but doesn’t mold as closely to the body as memory foam (which is a matter of preference).

Latex sofa bed mattresses are heavier than other types, making moving, lifting, and cleaning a bit challenging. Always check the manufacturer’s specifications when purchasing a latex mattress, as mattresses with minimal latex can still be labeled as a latex mattress.


Sofa bed mattress sizes are not the same as standard bed mattress sizes, even though they use the same names for sizing. With an average height of 4 to 5 inches, sofa bed mattresses need to be thin so they can fold away when visitors leave. Length for sofa bed mattresses ranges from 68 to 74 inches, depending on the brand.

The widths for typical sofa mattresses depends on the type.

  • Twin mattresses are about 24 to 38 inches wide.
  • Full mattresses are about 39 to 54 inches wide.
  • Queen mattresses are about 55 to 60 inches wide.

When replacing the existing sofa bed mattress, measure the dimensions of the metal frame. Measure the width, length, and height of the inside of the metal frame, and round down to the next inch for proper sizing. If the replacement mattress is too big or too small it might not fold up properly, which could affect how it feels to sit on the sofa cushions and how the mattress wears over time.


Firmness is how hard or soft the mattress feels beneath sleepers. Many sofa bed mattresses come in a medium-firm feel. Generally, sofa bed mattresses are only about 4 to 5 inches thick, meaning they don’t have the depth to offer much additional softness. In general, a firmer mattress keeps the body better aligned, and choosing a firmer mattress is often good for the back.

Foam mattresses use indentation force deflection (IFD) as an indication of how firm the foam feels and how much movement there is when weight is added. A higher IFD indicates a firmer foam, which usually ranges from 40 to 60. Softer or medium foams are in the range of 20 to 30. Memory foam also uses IFD, which softens when the foam warms from body heat, changing the IFD.

Each mattress is made differently, and comfort can be affected by different construction styles, making comparison difficult. The best way to determine how a mattress feels is undoubtedly by trying it out, though this isn’t always practical.

Trial Period

Before purchasing a mattress, find out the seller’s policy on returning or exchanging the sofa bed mattress. Some companies allow buyers to return products that don’t meet their comfort standards within a certain timeframe, whereas others take returns only if there is a defect with the product or if it is covered by a warranty.

Once the replacement sofa bed mattress has been installed, it is a good idea for users to try it out for a few nights rather than waiting for an overnight guest to give their review. By personally experiencing it, the level of comfort is known, and buyers can be confident their visitors can get a good night’s sleep.


You’ve selected a new sofa bed mattress and want to take care of it so it lasts as long as possible. We’ve assembled some frequently asked questions and their answers to help you get the most from a new sofa bed mattress.

Q. Can you replace the mattress on a sofa bed? 

Yes, you can. Measure the dimensions of the sleeper sofa to ensure you get a replacement mattress that fits properly when the bed is set up and when it’s folded away.

Q. How are sofa bed mattresses measured?

Sofa bed mattresses come in various sizes, such as twin, full, or queen; however, they don’t adhere to an industry size standard, so length and width can vary. These are considered “short” versions of traditional-size mattresses.

Q. How can you remove a smell from a sofa bed mattress? 

You can deodorize a mattress using simple household products. Lightly spray an equal mix of water and white vinegar over the mattress and let it air-dry, or sift baking soda over the mattress and vacuum it up after 30 minutes to remove smells and boost freshness.

Q. What are the best types of mattresses for a sofa bed?

Some of the most popular options include memory foam, innerspring, and latex mattresses. Memory-foam mattresses are a popular choice due to their ability to conform to the body and provide excellent support, while innerspring mattresses offer a more traditional feel with good support and breathability. Latex mattresses are also a good option for sofa beds, as they offer excellent support and durability. Ultimately, the best type of mattress for a sofa bed will depend on your personal preferences and needs.
