Milliard 4.5 Inch Memory Foam Replacement Mattress with Breathable. Waterproof and Washable Cover for Full Size Sleeper Sofa and Couch Beds – Full

It fits the sofa bed as described, wished it was a little thicker, I haven’t tried it yet it’s in my RV but should be better than the old spring mattress. Time will tell, I will use a pillow topper on it for extra comfort as I did with the old original mattress. Only four stars for now because it fit, was as advertised and the quality appears to be ok.

So far I think this mattress is a huge improvement over the box spring mattress that it replaced, I haven’t had it long enough to know how well it will hold up as a long term item.

The mattress works well and is a decent thickness. It is almost too thick for my sofa bed because the top part of the mattress seems to curl up a little. However I slept on this for a few days and got a good nights sleep. P.S. I didn’t notice a smell.

Item arrived sealed in plastic but had a spot in the cover. I’d rather it didn’t come already stained but it looked like something that happened in factory while packaging or something and it is minimal. Also, the cover is washable and I was covering it with a mattress pad and sheets so I wasn’t too concerned. I opened the zipper and let it sit for three days to fully expand. Then I zipped the cover and put the bed away. Took a minor bit of wrestling to get it folded into the sofa the first time, second time much easier. My parents slept on for 5 nights and said it was very comfortable. I’ll try to remember to update after time/use have shown it’s longevity.

Measure your frame! We have a queen size and this mattress is too small -- I didn't measure my frame beforehand and trusted the "queen size" so I'm not deducting from the rating because that was my fault. This is just a word of caution to everyone else. Expensive mistake.

That being said, it is significantly more comfortable than the mattress that came with the bed. I can feel where the bar is, but it is very minimal and so much better than before. I think this is a great purchase and it was worth the money. It is a tight squeeze to fold back up, but it does fold back up.

When I got the mattress I was excited. I used it once or twice but noticed it wasn't getting any bigger. I realized that I ordered the wrong size and now I would have to return it. There were no issues requesting a return. Very punctual with my request. The problem is that since it expands it no longer fits in a box. I've been struggling with it ever since. Definitely my oopsie but it's not very easy returning such things. Double check the sizing your getting ! Overall it's nice. It's obviously not very thick it's not meant to be but this one was the thickest I could find and it works as intended. The only thought I had was that it was maybe more pricey than other ones but it does have a nice quality to it.
