Best Coil

The Best Sofa Bed Mattress Options Leggett

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: Not specified
  • Mattress Size: Queen or full


  • Hypoallergenic; great for sensitive sleepers
  • Firm, supportive innerspring design

Types of Sofa Bed Mattresses

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

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 should be 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 their affordability and airflow. These mattresses usually feel quite firm, which can benefit some people with back pain. Using a coil mattress with more 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. And 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 cause guests 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.

What to Consider When Choosing the Best 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.


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 beds are:

  • Twin, measuring 24 to 38 inches,
  • Full, measuring 39 to 54 inches, and
  • Queen, measuring 55 to 60 inches.

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.


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 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 by trying it out yourself.

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 time frame, whereas others take returns only if there is a defect with the product or if you have a warranty.

Once you install the replacement sofa bed mattress, try it out yourself for a few nights rather than waiting for an overnight guest to give you a review. This way you know exactly how comfortable it is and whether visitors can get a good night’s sleep.


You’ve selected your new sofa bed mattress and you 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 your 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.
