Best Memory Foam Mattress Toppers for Convertible Sofa Beds

How Do I Make My Convertible Sofa More Comfortable To Sleep On?

Futons and convertible sofa beds are not known to be the most comfortable beds in the world and even when you splurge and buy a fancy one that still doesn’t mean it will make a super comfortable bed for sleeping on regularly. Luckily there’s a simple way to make futons, sleeper sofas, and even old mattresses more comfortable. The secret is memory foam mattress toppers.

A big problem with sofa beds is there’s always a bar running through the middle of the mattress that digs right into your back. And with futons, you end up wedged between the seat cushion and the backrest. A 2-3″ memory foam topper fixes all these problems by distributing your weight more evenly on the sofa frame and getting rid of those unpleasant gaps.

The problem with convertible sofa beds is they are oddly sized and there’s not a lot of mattress toppers that can fit them perfectly. The magic of memory foam is it’s easy to cut if you buy the kind that doesn’t use fiberglass. You also want to get the style of memory foam that is softer because convertible sofa beds are known for being very firm.

In this article, I will review some of the best small mattress toppers that will fit your futon or convertible sofa bed and turn it into a bed you will want to sleep in at night. For more information on sizes and why the twin mattress size is the best option for most futons and convertible sofa beds check out the FAQ section below.

Linenspa 3-in Convoluted Gel Swirl Mattress Topper

Linenspa 3 Inch Convoluted Gel Swirl Memory Foam Mattress Topper - Promotes Airflow - Relieves Pressure Points - Full

Check Price on Amazon

You’ve seen the standard smooth memory foam topper but another great option is the convoluted memory foam topper. Convoluted or more commonly known as “egg crate foam” is softer than standard solid foam. It can make even the most firm and uncomfortable convertible sofa bed soft and comfortable.

Linenspa makes a fantastic convoluted gel-infused memory foam mattress topper that can be 2 or 3 inches thick depending on your preference. When it comes to egg crate foam I always suggest the thicker version like 3 inches because they are measuring from the tops of the bumps and you want more material to be under the dimples or holes in the foam.

The bumps not only make the memory foam softer it also breathes better. You will be hugged by the foam in a pillowy softness but it won’t overheat your body.

Another plus to egg-crate style foam is it’s easier to cut down to the size you need making it perfect for futon beds.

There are also a lot of options as far as thickness goes. you can choose from 1.5, 2, 3, and even 4 inches. Each one comes in the standard mattress sizes including twin which is the best choice for futons. I think the 3-inch options will be the best for a firm futon or sleeper sofa but you can customize the thickness according to the firmness of your sofa bed and your personal preferences.

As a side note, the 4-inch version is actually a 3-inch convoluted memory foam with a 1-inch gel-infused topper. So it comes in 2 pieces which can be more work to set up every day on your futon or sleeper sofa bed.

My Choice For Best Memory Foam Mattress Topper For A Convertible Sofa

Zinus 3-in Swirl Gel Mattress Topper

Zinus 3 Inch Swirl Gel Memory Foam Air Flow, Full Topper

When you get a futon or convertible sofa to use as a bed you don’t want to spend even more to make is decent to sleep on. That’s why mattress toppers are a great way to make sofa beds more comfortable. They are also easy to roll up and store in a closet or even behind the futon or sleeper sofa.

The Zinus gel memory foam mattress topper is my number one choice because it’s softer than non-convoluted memory foam. You want to add softness to firm sofa beds, not more firmness. They are also lighter and easier to carry around.

Zinus gives you a lot of options when choosing a thickness which is important because not all sofa beds are the same firmness and not everyone likes the same softness when it comes to a bed. This way there is a choice for everyone and every futon or sofa bed.

It’s also easier to cut down to the right size which is something you most likely will end up doing especially if you have a convertible sofa that has permanent armrests.

Taking all of these things into account is what makes the Zinus 3 inch egg crate gel memory foam mattress topper the best choice for futons and convertible sofa beds.

Convertible Sofa Bed Toppers Frequently Asked Questions

What size of mattress topper do I buy?

Most classic futon beds are around 38″-44″ wide and anywhere from 65″-71″ long. A twin size mattress topper is 38″ wide and 75″ long. Depending on the size of your futon or convertible sofa bed you may need to cut the mattress topper down lengthwise but it should fit fine as far as width goes.

Most simple futons don’t have armrests and you can even just throw the twin size mattress topper on top and let it hang over the edges no cutting necessary.

Sofa sleepers normally have a standard size of a mattress. You can normally get a full or even queen size memory foam mattress topper that will fit them perfectly. Or better yet replace the cheap mattress your sofa sleeper has with a better 5-6 inch memory foam mattress. Then you don’t have to worry about storing the topper somewhere else when not in use.

How do I cut memory foam?

When cutting memory foam the most important thing is to make sure it’s not made with fiberglass. None of the memory foam toppers on this list contain fiberglass and will be fine to cut but some cheaper larger memory foam mattresses do contain fiberglass and you don’t want to open up and cut that kind.

Fiberglass free memory foam like the toppers in this article and even the mattresses on this list (click to view) are fairly easy to cut down to the desired size. The thinner the foam the easier it is to cut. Mattress toppers can normally be cut with just a large pair of fabric scissors. just make sure you remove the cover, if it has one, first. If it’s too thick for scissors box cutters work well just make sure you cut little bits at a time.

Can I fold the mattress topper inside my sleeper sofa?

If you didn’t buy a mattress topper that is too thick you should be able to fold it up with the mattress in the sleeper sofa. You may even be able to keep the mattress topper on a futon if you buy a cover for it so it will stay in place when you incline the backrest to the seated position.

Is gel-infused memory foam softer than regular memory foam?

Gel-infused memory foam has a faster bounce back rate than regular memory foam which means it’s softer to lay on. That’s why gel-infused memory foam is a better topper for futons and convertible sofas than regular memory foam.
