Classic Brands 4.5-Inch Cool Gel Memory Foam Replacement Mattress for Sleeper Sofa Bed Twin, Plush

Bought this to replace an old mattress on a couch bed given to us. This is a great replacement mattress. It expanded pretty quickly, I let it sit out for 24 hours though to give it a lot of time. It has no off gasing, and has been used by a child and adults up to 200 lbs. Everyone said it was very comfortable and they didn't feel the bars underneath. It fit perfectly in our sofa bed, and folds up easily and expands right back up when we take it out. It's been used several times since we bought it, and we've been very happy with it. I would recommend this mattress.

This mattress made an excellent replacement to our thin springy mattress that came with our pull out chair. It inflated quickly snd was exactly 4.5 inches. There was no smell and itarrives well packaged. Size, fit perfect and its firm yet provides great support. We upgraded as our boys friends have all gotten older and were complaining about the old mattress. First night on this one got raving reviews on sleep quality. Our other son even wanted to sleep on it over the couch which used to be his choice. Holds up to 160+ lb teenagers.

The mattress arrived quickly and was easy to unpack and position on the sofa bed. It fit perfectly. It is MUCH more comfortable than the original innerspring mattress which had become impossible to sleep on. I expect this mattress to give my guests a much better sleep and to give the sofa bed many more years of use!

Purchased this to replace the original mattress in my Lazy Boy twin sleeper. It has made a world of difference in the comfort level and fits perfectly. Would buy again.

This mattress comes vacuum packed and looks really thin when first unrolled, but once you let it rest it fluffs up. I was worried this would mean it wouldn't be supportive but it's actually a very comfy memory foam mattress. We use it on a top bunk of a twin bunk bed, and it's perfect with one minor caveat: it's about 4-6 inches narrower in width than a standard twin mattress, so be prepared to address that. We put an egg-shape foam topper on top and that kind of covered over the gaps in either side and it works fine.

Bought this mattress to replace an old regular mattress in a sleeper loveseat. Great decision though I think a thicker mattress would have fit and gave even more comfort/support...as it's memory foam and compresses. Company who has slept on it says it was very comfortable and couldn't feel that bar in the frame. Not sure if a 250# person would feel the same. Packed well, no smell. Happy with purchase.

The product never fully expanded and was no where near 4.5 inches. It is impossible to return because you cannot get something that was vacuumed sealed in a bag back in the original box it was sent in. Also, even if you have prime, you have to pay for the shipping to return it. You can feel every bar of the sleeper sofa through this mattress but maybe that’s because it didn’t expand fully. Complete waste of money. I would not recommend it.

Great replacement mattress for fold down sofa provided that you don't need to fold it back in with the mattress. It's a bit too thick to manage that. Very comfortable and durable. No smell. Fluffy up great.

This is great if you’re adding it as a topper to a bed or if it’s going on a completely flat surface but if you have a slat bed or are using it for a pullout with bars, you are going to feel every single bump.

it is not as thick as expected and is still off gassing. I could not use it over Christmas as I expected.
