When is the last time you slept on a pullout couch? When they first came on the scene, sofa beds were a convenient way to have overnight guests. It’s like the mullet of the furniture world: Business by day, party at night – or you know, you could use it as a couch during the day, and a bed at night.

Back in the day, though, sofa beds weren’t exactly comfortable. Thin mattresses with creaky springs and a big metal bar in your back didn’t make for a good night’s sleep. They’ve improved so much over the years with thicker mattresses, but you still may get one that isn’t the most comfortable to sleep on. The good news is that you can swap out the mattress for a better one.

The Best Sofa Bed Mattresses

1. Zinus Sleep Master Cool Gel Memory Foam 5-Inch Sleeper Sofa Mattress

SPECS

  • 5-year limited warranty
  • CertiPUR-US Certified
  • 60 x 72 x 5”
  • 30 pounds
  • Medium Firm
  • Gel memory foam

You can treat your overnight guests to a more comfortable night in your home when you swap out your old sofa bed mattress for a Zinus Sleep Master Cool gel memory foam 5-inch sleeper sofa mattress. Four inches of high-density support foam is the base of this mattress. This is what should protect you from the bars of a sofa bed.

On top of that four inches is a one-inch thick layer of gel-infused foam. This layer is what provides the cushy comfort you want in a mattress. Plus, the infusion of gel offers a layer of protection against heat retention that memory type foam is notorious for. The whole thing is covered with a textured, soft removable cover.

You may notice a little bit of a smell when you unpackage your mattress for the first time, but the scent should dissipate quickly. Many have slept on this mattress on a foldout couch and said they didn’t feel the bar at all. Perhaps the biggest complaint is that the mattress is too thick, and it’s difficult to fold it up into their sofa beds. A five-year warranty is included, which is great to protect you in case you get a lemon of a mattress.

Pros

  • Comfortable
  • Sleeps cool
  • Affordable
  • Includes removable cover
  • Little to no off-gassing

Cons

  • May be too firm for some
  • Might not fit all sofas

This is a medium-firm memory type foam mattress with a layer of gel-infused foam to help mitigate some of the heat, and it may make a good replacement for standard sofa bed mattresses.

SPECS

  • 3-year limited warranty
  • CertiPUR-US Certified
  • 58 x 72 x 4.5”
  • 37 pounds
  • Medium Firm
  • Memory foam

A sofa bed without a comfortable mattress is really only good as a sofa. If guests are showing up at your house with an air mattress in tow, even knowing about the sofa bed as an option, you might want to consider replacing the mattress in your couch. The Classic Brands foam replacement sofa bed is 4.5 inches thick, which provides a comfortable, supportive surface, but should still be thin and flexible enough to fold up easily.

You may notice that the measurements of this mattress are smaller than a typical queen-sized mattress, and that’s to make sure it fits in sofa beds. The base is made up of high-density foam to provide the thick support for those who sleep on the sofa bed, and to act as a shield to prevent you from feeling the metal bars underneath. The top layer is two-inches of foam that’s meant to give you the comfort you want from a mattress.

As with almost any foam product, there’s going to be a bit of a chemical smell when you first open the package. This one has a slight off-gassing, but it’s minimal. Although this is a breathable mattress, it may be a bit warm for some people.

Pros

  • Antimicrobial
  • Breathable
  • Affordable
  • Comfortable
  • Should fit in any fold-out sofa

Cons

  • A bit of off-gassing
  • May sleep a bit warm

If you need a replacement for your sofa bed mattress, this high-quality foam option could be what you need to give your guests a better night’s sleep.

3. Eco Mattress Store Sleeper Sofa Memory Foam Mattress

SPECS

  • 7-year limited warranty
  • 60 x 72 x 4.5”
  • 30.2 pounds
  • Medium
  • Memory foam

It’s easier than you think to replace the sofa bed mattress you’ve had for years. Choosing the right one for you comes down to personal preference and picking one that fits in your sofa. The Eco Mattress Store sleeper sofa foam mattress is similar to others on the market that are about 4.5 inches thick.

The differences are likely in the density of foams used in this mattress compared to others. Although it’s 4.5 inches thick, many have said it isn’t thick enough to disguise the metal bars on a sofa sleeper. With that said, many others have said it’s a comfortable mattress to sleep on, whether it’s on a bed, floor, or sofa bed.

It’s a mattress that’s thin and flexible enough to fold up easily into a sofa bed, so you shouldn’t have any issues with fit. There is a little bit of off-gassing, but the smell should go away in a day or so. The measurements given by the manufacturer are equal to a standard queen-sized mattress, however, many have said this mattress is one to two inches narrower. The seven-year warranty is one of the most generous for replacement sofa bed mattresses.

Pros

  • Comfortable
  • Fits most sleeper sofas
  • Affordable
  • Very little off-gassing

Cons

  • May not be thick enough
  • Measurements may be off

If you’re having trouble fitting a mattress in your sofa bed, this memory foam mattress may be a good choice.

SPECS

  • 60 x 72 x 4.5”
  • 36 pounds
  • Medium
  • Memory foam

Buying a new mattress for a sofa bed used to be difficult, but now you have more choices than ever. The Lifetime Sleep Products sofa sleeper replacement foam mattress follows the trend of using foam rather than innerspring coils for sofa bed mattresses. The two-inch base layer of foam is thick enough to mask the feel of bars that seem to always poke through when you sleep on a sofa bed.

The top layer is about two-and-a-half-inches of thick memory foam that’s meant to provide a comfortable sleeping surface. The size of this mattress is the same as standard queen mattresses, but it should fit in your sofa bed easily. Some have said it’s too thick to fold up and back into the sofa, while others say it’s too thin and they can feel the bars through the mattress.

There’s not much off-gassing with this mattress, but there may be a bit of scent. Just give it a day or so to let the mattress air out after you unpack it and it should be fine. Compared to other mattress replacements, this one is a bit pricier, but it’s still affordable.

Pros

  • Comfortable
  • Fits most sleeper sofas
  • Very little off-gassing

Cons

  • Sleeps warm

If you need a replacement mattress for your sofa bed, this could be a good choice, or even use it as a topper to your original sofa sleeper mattress.

What is a Sofa Bed?

Pull Out Sofa Bed

If you’ve never owned a sofa bed, then you might not know exactly what it is. It’s different from a futon in that it’s a full sofa with cushions and armrests. When you pull the cushions off, though, there’s a bar that you can pull on and out pops a metal bed frame with a foldable mattress on top.

It’s been a popular choice for overnight guests since it was introduced in the late 1800s. It didn’t really become mainstream, though, until it was perfected in 1931 by Bernard Castro. Of course, if you’ve ever slept on a sofa bed, you may think that it has yet to be perfected. The design allows for a mattress to fold in half, and for that to happen and to offer the proper support, there ends up being a metal bar in the center.

The problem is that many of the mattresses that come with a sleeper sofa are too thin, so you end up feeling that bar in your back as you sleep. Mattress companies have finally figured that out, and many of them have responded with a new type of mattress – new for sofa sleepers, anyway.

Why Would You Want to Swap the Mattress?

Most sleeper sofas sold come with a thin innerspring coil mattress. These are made with evenly spaces springs that provide loft and bounce to make for a comfortable and supportive sleep. Typically, though, they don’t work the way you’d hope, especially when there’s a center bar in your sofa bed.

Decades ago, innerspring coil mattresses were essentially the only choice most people had or could afford. Now, though, memory foam, gel memory foam, latex, and other types of foam mattresses are affordable, easy to buy, and you don’t even have to go to a mattress store to pick one up.

Memory foam mattresses are typically firmer in feel, which means they would be more comfortable on all types of surfaces. Generally, the foam needs a solid surface to prevent them from sinking in between bars. So, depending on the way your sofa bed is made, this could be an excellent choice.

Gel foam works the same way as memory foam, but the gel offers a reprieve from the heat that often gets trapped in foam mattresses. If you or guests tend to sleep hot, this could be a good choice for your sofa bed.

Still, sofa beds usually come with innerspring coil mattresses, and there are some who still prefer this type of mattress for a sofa bed. They definitely make for a bouncier feel when you sit on your couch, and when you sleep on the pullout bed.

What Type of Mattress is the Best?

Both innerspring coil and foam mattresses fold easily, depending on the density, which makes them good choices for a sofa bed. A memory foam mattress may edge out an innerspring coil mattress because they retain their shape better; it should pop back into shape every time you unfold your sofa bed.

In the end, it comes down to personal preference, though. It’s a good idea to read through reviews of mattresses meant for sofa beds. So, take a look at the best mattress for sofa type beds below and choose the one that’s best for you.

Conclusion

Memory foam has come a long way, and now it’s available in replacement mattresses for sofa beds. It’s surprising how comfortable a sofa sleeper can be when it has the right kind of mattress on it. Although many of the mattresses on this list are great choices, there is one that stands out above the others.

For comfort and support, the Zinus Sleep Master Cool Gel Memory Foam 5-Inch Sleeper Sofa Mattress is probably your best bet. It’s one of the most affordable options at about the same price as an innerspring coil replacement mattress. It’s been stamped CertiPUR-US certified, and it comes with a five-year warranty. If you have any issue, it could be that the mattress may be too thick to fit in your sofa bed, but most people didn’t have a problem at all. Did you find the best sleeper sofa mattress here?
