Best Memory Foam Mattress for Sofa Bed | Comparison of Top 5 Sofa Bed Mattresses

A sofa bed sometimes referred to as a hide-a-bed or sleeper sofa is a furniture piece designed to perform two functions: bed and sofa. You can lie down on a sleeper sofa to read a book or watch television, or seat down on it and spend quality time with friends and family.

Sofa beds are also great for overnight visitors. The mattress pulls out easily from your couch, converting a living room into a makeshift visitor’s room.

It is, however, common knowledge that nearly all mattresses that come with sleeper sofas are very uncomfortable and provide very little support.

They are thin, inadequately constructed, and typically cause you to sleep restlessly. And, you may even feel the springs or other interior structures jabbing at your back.

In contrast, memory foam mattresses provide advanced comfort plus pressure point support. In this post, we recommend 5 of the best memory foam mattresses for sofa beds.

We will also bring you the top tips to bear in mind when selecting the best memory foam mattress for your sleeper sofa.

If you are searching for a replacement hide-a-bed mattress that will give you or your visitors optimal sleep comfort, you cannot go wrong with this 5-inch mattress by Zinus.

The two-layered mattress features a high-density support foam base that is 4 inches thick plus a gel-infused memory foam top that is 1-inch thick.

The base support foam helps provide enough cushioning to ensure you do not feel the bars of the sofa bed’s mechanism. The gel-infused upper layer helps provide the welcoming comfort one would expect from a mattress.

With these two layers, your sofa bed will be a lot more comfortable. All the above reasons make it the best memory foam mattress for sofa bed.

And, since it comes off, cleaning your mattress will not present any hassles as you can simply remove the cover and wash as required.

The mattress also contours to your body angles and shapes thus ensuring that your spine stays within a neutral position.

Usage Guide

As soon as you take delivery of your mattress in a box, it is recommended you open it up within 72 hours. Leaving it within the enclosure much longer than 72 hours may lead to extended recovery time.

Do not use any sharp objects when removing the plastic cover to avoid damaging your new mattress.

After removing the hide-a-bed mattress from its packaging, the manufacturers recommend that you walk or roll on the mattress. Doing so will help to open up tiny air pockets so the mattress can expand.

Leave the mattress within a warm room (approximately 70 degrees). This will encourage the mattress molecules to move around thus causing the mattress to undergo thermal expansion.

Leave the mattress within the room for approximately 24 hours for it to open out to its regular size. If you observe any off-gassing (aka new mattress smell), do not be bothered by that as it will fade within one or two days.

How to Select the Best Memory Foam Mattress for Sofa Bed?

Below are some critical factors you need to consider before you settle for a particular memory foam mattress for sofa bed.

1. Size

Best Size of Memory Foam Mattress for Sofa Bed

Size is perhaps the most important consideration when selecting a mattress for sofa. These mattresses come in a range of sizes including full, queen, or twin.

While they use similar names for sizing, sizes of sofa bed mattresses are not equivalent to that of traditional bed mattresses.

Mattresses for sofa must be thin so it is easy to fold them away when guests leave or when they are not in use. This is why their average thickness is 4-5 inches.

Before you go shopping for a new mattress for sofa, be sure to measure the height, width, and length of your bed’s metal frame. For adequate sizing, you should round down the results to the next full value.

If you purchase a mattress that is excessively small or large, you may have difficulty folding it up, and this can affect the mattress’s comfortability.

The products recommended in this post are all adequately sized to fit most traditional sofa bed mattresses however the Zinus Memory Foam 5-inch Sleeper Sofa Mattress is the winner here due to the superior comfort and support it offers.

The mattress is the thickest on this list, which means it will provide the best cushioning against the metal bars underneath the mattress. Also, because it contains more foam, it will almost certainly last longer compared to the other options.

2. Firmness

Firmness of Memory Foam Mattress for Sofa Bed

Firmness denotes the degree of softness or hardness of the mattress. Several pull-out sofa mattresses have a medium-firm feel. Memory foam mattresses for sofa generally have a thickness of approximately 4″ to 5″.

This means they may not be thick enough to provide enough cushioning and firmness. Generally, firmer memory foam beds accommodate nearly all sleeping positions. These mattresses offer an ideal balance of support & comfort.

However, always remember that comfort is subjective. What is appropriate for one individual is not always appropriate for another. Testing out the mattress yourself is the best method to ascertain how comfortable or firm a mattress feels.

If you are seeking a comfortable memory foam mattress that is firm enough to help reverse back pain, then the Zinus Memory Foam 5-inch Sleeper Sofa Mattress should top your list of options.

3. Certifications

Certified Memory Foam Mattress for Sofa Bed

Selecting the appropriate mattress is essential for sound sleep, yet with loads of options in the market, buying one can be demanding and confusing.

If you want to select a product that does not contain injurious chemicals that can harm your health or that of your guests, then, you should select a product that has been endorsed by a trustworthy quality control board.

The CertiPUR-US certification is arguably the most essential certification that any mattress can receive. This certification signifies that a product has been rigorously tested and found to be free of injurious substances including flame retardants and heavy metals.

All the products recommended here have all gotten the Certi-PUR-US certificate, meaning they will not emit dangerous off-gassing.

4. Warranty

It is recommended that you select a mattress that is backed up by a warranty. A warranty indicates that the makers have faith in their product.
