Best Sofa Bed Mattress Topper Reviews

1. Best Price Mattress 4-Inch Memory Foam Mattress Topper, Queen

SPECS

  • Sizes available: Twin, Twin XL, Full, Short Queen, Queen, King, California King
  • Dimensions: 80 L x 60 W x 4 D (Queen)
  • Weight: 29 lbs.
  • Material: Memory foam, polyester
  • Warranty: 5 years

Finding a mattress topper for a sofa bed is easier than you think, and when you need extra support, along with comfort, the Best Price Mattress 4-inch memory foam topper might be just right. It’s made of two layers of foam. The bottom half is made up of high-density support core foam, and the top half has a softer comfort layer. Together they work to cradle your body and it should mask any metal bars poking up through your sofa bed’s mattress. The removable cover is also machine washable, which is a huge plus. Also, this topper is an affordable choice, and it comes with a long 5-year warranty. Perhaps the biggest issue with this memory foam topper is its thickness. At 4 inches thick, it’s unlikely you’re going to be able to fold this up and into your sofa bed. Also, it tends to sleep hot, so you might need to crank up the air conditioner for guests.

Pros

  • Includes a removable, washable cover
  • Medium-firm support
  • Comfortable
  • Affordable

Cons

  • Won’t fold into a sofa
  • Sleeps hot

When you need a topper that offers support and softness, this one from Best Price Mattress could be a great choice.

2. SleepBetter Iso-Cool Memory Foam Mattress Topper with Outlast Cover, Queen

SPECS

  • Sizes available: Twin, Full, Queen, King, California King
  • Dimensions: 77 L x 58 W x 3 D inches (Queen)
  • Weight: 30 lbs.
  • Material: Memory foam, polyester fiberfill
  • Warranty: 5 years

The SleepBetter Iso-Cool memory foam mattress topper is meant to provide the comfort and support you want from your bed, but without generating even more heat. Depending on the comfort of your sofa bed, this topper could provide even more form-fitting comfort. It’s the removable cover that helps ventilate your topper, which helps keep things cooler. Don’t expect to be sleeping on an air-conditioned bed or anything, though. Many people have described sleeping on this mattress topper being akin to sleeping on a cloud, but that’s also about personal preference. Keep in mind that the heavier the sleeper is, the more the memory foam will sink down. The good news is that the cover is washable, so that’s a nice feature. This is about a 3-inch thick mattress topper, so it may not fit every sofa bed when folded up.

Pros

  • Sleeps cool
  • Makes a firm mattress softer
  • Long warranty
  • Removable, washable cover

Cons

  • May flatten quickly
  • May be too thick to fold up
  • Expensive

This may be a good mattress topper for your sofa bed if the mattress it sits atop is a bit thin, so it folds up properly in the sofa.

3. LUCID 2-inch Gel Memory Foam Mattress Topper – Queen

SPECS

  • Sizes available: Twin, Twin XL, Full, Full XL, Queen, King, California King
  • Dimensions: 80 L x 60 W x 2 D inches (Queen)
  • Weight: 15 lbs.
  • Material: Memory foam, gel
  • Warranty: 3 years

LUCID has addressed the issue with memory foam that’s most common: Dense foam traps heat. It’s an unfortunate reality, and it can be worse for some sleepers who tend to sleep hot. So, the manufacturer tried to take care of the heat issue in two ways. One, the memory foam is ventilated to help with breathability; and two, the foam is infused with gel, which helps keep sleepers cool. For the most part, it works, but it isn’t guaranteed to work for everyone. Some people said it still traps heat. Using this mattress topper on your sofa bed is a no-brainer. Just throw it on top and it should add an extra layer of softness. You shouldn’t expect much support, though, as this isn’t made of high-density foam. It is flexible enough, so if your sofa bed has room to fit a mattress and topper, you should be able to fold this up and into your sofa. If you’re concerned about cracking, though, you could roll this topper up and store it in a closet until you need it.

Pros

  • Adds softness
  • Flexible
  • Decent warranty
  • Affordable

Cons

  • Doesn’t offer much support
  • May be too thick to fold up
  • Doesn’t have a washable cover

If you’re looking to add softness to a sofa bed mattress, this topper is affordable and could be a good choice for you.

4. Balichun Mattress Pad Cover Queen Size Pillowtop with 8-21-Inch Deep Pocket

SPECS

  • Sizes available: Twin, Twin XL, Full, Queen, King, California King
  • Dimensions: 80 L x 60 W x 1.5 D (Queen)
  • Weight: 6.2 lbs.
  • Material: Polyester fiberfill
  • Warranty: N/A

This is one of those pillowtop mattress pads that are soft and squishy and often compared to clouds. Instead of filling this one with goose feathers or down, a down alternative is used, or a fiberfill. One of the best things about this mattress topper is that it’s only about 1.5 inches thick, so it’s sure to fit inside your sofa bed when you fold it up. The bad news is that the mattress topper isn’t going to offer you much support. As long as you have a quality mattress on your sofa bed, this topper could offer you or your guests some extra loftiness that might be missing. The topper is lightweight, so you can easily toss it onto your sofa bed, and it’s machine washable – a huge convenience. Although the pockets on the stretchy sides of this mattress topper will fit almost any mattress, it could shift a bit if the mattress it’s on is thinner.

Pros

  • Machine washable
  • Adds pillow-like softness
  • Lightweight
  • Affordable

Cons

  • No support
  • May shift on the bed

If your sofa bed just need a little extra softness, this pillowtop mattress topper could be a good addition for your guests.

5. Red Nomad – Queen Size 3-Inch Memory Foam Topper

SPECS

  • Sizes available: Twin, Twin XL, Full, Queen, King, California King
  • Dimensions: 78 L x 58 W x 3 D (Queen)
  • Weight: 26.2 lbs.
  • Material: Visco-elastic foam
  • Warranty: 5 years

The decision to add a mattress topper to your sofa bed means investing in something that you hope makes your guests more comfortable. The Red Nomad 3-inch mattress pad is made of visco-elastic foam, which provides a little support and a lot of comforts. This isn’t the same as memory foam, so you shouldn’t expect a super-dense topper, but it is a flexible and comfortable option. The best part about adding this mattress topper to your sofa bed’s mattress is that it’s flexible enough to easily fold up inside your sofa bed when it isn’t in use. Unfortunately, it comes with no cover, so you may need to buy a mattress protector to keep it clean. Plus, because it’s foam, it may sleep hot for some people, though it won’t trap heat as badly as the others.

Pros

  • Adds medium support
  • Comfortable
  • Affordable
  • Fits inside sofa bed

Cons

  • No cover included
  • Sleeps hot

This might be a good choice for those who need a mattress topper for a sofa bed that’s going to stay on the mattress, even when folded up in the sofa.

6. SleepJoy 2″ ViscO2 Ventilated Memory Foam Mattress Topper, Queen

SPECS

  • Sizes available: Twin, Twin XL, Full, Queen, King, California King
  • Dimensions: 78 L x 58 W x 2 D (Queen)
  • Weight: 12.9 lbs.
  • Material: Memory foam, polyurethane
  • Warranty: 2 years

A ventilated memory foam mattress topper, like this one from SleepJoy, is meant to keep you cool as you sleep on it, and for the most part, it does. Sleep temperature is a matter of personal preference and climate, though. It may be worth it to add a cooling cover, for those who tend to sleep hot. Putting this on top of a thin sofa bed mattress shouldn’t be an issue at all. It’s thick enough to offer comfort but thin and flexible enough to fold up into a sofa. Many foam mattress toppers have a bit of an off-gassing period of a couple days, but this one, in particular, has reports of it being extra smelly. You might want to air it out for a week or so before guests show up. Using this for a sofa bed is common, and those who have said it folds up easily and masks the feeling of bars beneath.

Pros

  • Easily folds up on sofa
  • Durable
  • Affordable
  • Comfortable

Cons

  • May sleep warm
  • Strong smell

This lightweight foam mattress topper is thin enough to fold up inside a sofa bed, and it offers extra comfort, which could be a good choice for you.

A Guide To Sofa Bed Mattress Toppers

Sofa beds can be both a blessing and a curse. It’s always convenient to have a pullout sofa bed for overnight guests, but it’s not always the most comfortable option. If your guests have started bringing along an airbed to sleep on at your house, even though you have a sofa bed ready to go, it might be time for you to consider adding a mattress topper to your sofa bed. These little slices of comfort can go a long way in making even the bumpiest, creakiest, and oldest sofa bed a cloud of slumber heaven. Choosing the best mattress topper for sleeper sofa comes down to personal preference, a few features you want to look for, and the right price point.

Even the Most Comfortable Sofa Bed May Need Some Help
No matter the age of your current pull out couch, there’s a chance that the mattress is thin, lumpy, or generally uncomfortable and can cause back problems. It isn’t your fault or your mattress’ fault. It’s just the nature of sofa beds. Consider your own bed right now. Your mattress, whether it’s a traditional innerspring bed, memory foam, latex, or hybrid, sits on a flat surface. That surface is typically a foundation of slats made of wood or metal, and your mattress never moves.

Now consider your pull out couch. It has to bend in the middle so it can fold up and back into the sofa frame. Because of this, there’s usually a thick metal bar or two in the center of the bed, and chances are, whoever sleeps on it is going to feel those bars in the middle of their back.

These things have improved considerably over the past few years, and many of the manufacturers have forgone the old innerspring mattresses in favor of foam beds. The flexible foam of today can bend and fold and then unfold again without breaking, cracking, or tearing. This makes them ideal for sofa beds. And if you get one that’s dense enough and thick enough, you may not even notice the metal bars.

Still, over time, a couch-bed mattress could get uncomfortable, and if your guests start complaining of sore backs, you want to fix the issue. If you can’t afford to replace the whole mattress, you might want to consider getting a topper for your mattress to help make their stay a little more comfortable.

Types of Mattress Toppers

You have a bit of choice when it comes to adding an extra layer of comfort to your convertible couch. Just like mattresses, the toppers that make sleeping on a subpar bed more inviting, come in a variety of materials.

• Feather
These are like a giant feather- or down-filled pillows for your bed. There’s even feather down alternatives you can try. While they offer quite a bit of softness, they don’t give much support. You’d still likely feel a bar beneath you if your couch bed’s mattress is thin. Also, buying one of these is a bit of a crapshoot because your guests may have allergies.

Memory Foam
You know this material. NASA started the craze, and one big-name company seemed to corner the market since the 1980s. But many other mattress companies jumped into the game and started creating these foam mattresses with its bounce-back feature. When you use a memory foam mattress topper, it’s like slicing off the top layer of a memory foam mattress.

Latex
These toppers look a bit like their foam counterparts, but they’re made of all-natural latex. That drives the cost of these mattress toppers up, but they do offer a balance between comfort and support. They also tend to dissipate heat better than foam.

Hybrid
Plenty of bed topper manufacturers blend two or more materials to make a hybrid that’s cooling, comforting, and supportive. A good example is gel-infused memory foam to give you that hugging feeling when you sleep on it, but remains cool and doesn’t trap heat.

Pillowtop
When you need to add softness, but not necessarily support, a pillowtop mattress topper usually does the trick. These are typically pumped with fiberfill in little square pockets. If you have a good mattress on your sofa bed, this kind of topper will make it softer for the sleeper.

To Fold or Not to Fold
This question doesn’t have a strict yes or no answer. In some cases, a mattress topper can easily fit into a pull out bed even when it’s all folded up. In other cases, you could risk the material ripping or tearing. To ensure you don’t damage the topper, you should probably store it elsewhere and only pull it out when you have guests.
Some 2- to 3-inch mattress toppers can handle being folded up with no problem, and they’ll still fit in your pull out couch, but it may just take some trial and error. Another good way to find out is to read through reviews or a guide like this one that includes consumer feedback.

Verdict

The right mattress topper for your sofa bed depends a lot on what you need. If you already have a firm, supportive mattress on your sofa bed, you may just need an extra layer of softness. If you can feel the bars underneath you, a firmer, more supportive mattress topper could be a better choice. There is one topper that stands out overall, though. The Best Price Mattress 4-Inch Memory Foam Mattress Topper, Queen is an affordable option that provides support and comfort, which can both go a long way to disguising that metal bar in one’s back. It can definitely prolong the life of your sofa bed’s mattress, and it might even fit inside your sofa bed when folded up. If not, just roll it up and store it in a linen closet, if you have room. This mattress topper comes with a five-year warranty, which offers a bit of ease of mind in case of any defects.
