Milliard 4.5 Inch Memory Foam Replacement Mattress with Breathable, Waterproof and Washable Cover for Full Size Sleeper Sofa and Couch Beds (Sofa Not Included) - Full

It fit nicely in the foldable couch on which we placed it, and the couch easily folds back up with the Sofa Bed inside. It holds up well under usage, and it provides support and comfort.

Makes my old sofa bed feel as comfortable as a regular bed. My son gave this to me as a birthday gift to use in my small pied-à-terre NYC studio apartment. (He probably had an ulterior motive since he and his girlfriend occasionally use the apartment when they come in from out-of-town and mentioned that the old mattress was uncomfortable!) It was delivered free by FedEx within in 9 days coming from California. Since it was vacuum packed, the box was only about 4 feet tall and 1 foot wide (which another reviewer pointed out before I purchased it). My old mattress was 72" x 59". This one is slightly longer than advertised at about 72.5" (which was no problem in fitting my frame since the foam compresses a bit making for a perfect fit) but only 58" wide. However, this 1" difference is not a problem. The small space on the width of the frame is hardly noticeable. Furthermore it's no problem at all when sitting on the side of the mattress, say to get up or put on your shoes, since the foam is nice and firm. One of my concerns was that since my old mattress was only 4" thick and this one is 4.5", I might have a problem closing the bed. To my surprise it closed fine. The best feature is that you don't feel the support bars of the frame AT ALL! A great added feature is that it comes with a no-skid, washable zippered mattress cover for extra protection and comfort. All in all, this was a great buy. We'll see how well it holds up in the long run.

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.

Thorough Comfort. Excellent product- All the reviews here are on point. Excellent product! Very soft and comfortable. Exactly what I was looking for. It folds perfectly and comes with a mattress protector. The foam is thick enough to offer a pleasant rest. I am very happy with my purchase and recommend it 100%.

We've suffered with the old spring mattress on our couch that's probably 15 years old, so when I saw this replacement mattress on Amazon for 1/2 the cost of other online sites, I was pretty happy. It took me so long to even think to search for these things, but here I am. I just received it and set it up today. I bought the Full, so the measurements were supposed to be 73" x 52" x 4.5". As for length/width, it was fine and measures about 72.5" x 52.5"... slightly wider and slightly less tall than it's supposed to be, but that little bit of difference doesn't matter. As for the height, this has an identity problem. Some places it says it's supposed to be 3.5", but on the Amazon listing it says 4.5". Mine measures right around 4" tall, and that's right out of the box. It says you need to leave it set up to breathe for about 24-48 hours, but I don't think it's going to grow another 1/2". It is absolutely fine the way it is though. Granted, I'm not a big guy but I laid down on it and couldn't feel anything - best of all no springs!! Note, if you're expecting it to look like it does set up in the picture, that's not going to happen. To me it looks like the mattress in that photo is 6" or more - not 4.5" like it states. I don't even know how you would fold it if it was that big. Overall, this is a great replacement mattress, especially for the price. it is more comfortable than the old one and also pics up the cushions when folded so the couch doesn't sag as much. Would definitely buy this again.

I bought this specifically to replace the spring mattress that came with our sofa bed in our 5th wheel. The queen size fits well and expanded to the full advertising size. The metal frame and bars are not a problem anymore. Originally I had put a 2” memory foam topper on the springs but have been unhappy with that setup as the metal frame was still a nuisance. Furthermore, the extra mattress thickness made folding the bed in a problem. This mattress fold in properly. I’m 74 and 6’4” 245 and while I do not intend to use this as a primary sleeper, I could, I believe, use this sofa in a pinch without a problem. My wife agrees that we made a wise choice in this mattress and she feels comfortable using it as a secondary bed. No complaints. Hope this helps someone in there decision

Excellent product! Very soft and comfortable. Exactly what I was lookig for. It folds perfectly and comes with a mattress protector. The foam is thick enough to offer a pleasant rest. I am happy with the my purchase and recommend it one hundred percent.

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.

It came in a far more compacted state, in a much smaller box that we thought it would. An important tip is to, once you've unpacked it from the compressed bag it comes in (with a plastic bag cutter that is provided) it is best to let it expand fully, before tucking you sofa bed away. They say 24-72 hours on a flat surface, with we found to be more that needed, but is important to let it relax and expand. This mattress is night and day different on a comfort scale from the coil-spring one we replaced. So far we love it, and so have our guests. No more complaints!

Made a huge impact on our comfort. Highly recommend

This mattress has good support and fairly comfortable. It is 4 1/2” thick and a bit hard to fold into sofa bed base. With some effort , it worked. If it was 4” only, it would be better fit for sofa beds .overall, it is worth the money

We needed to replace the mattres on our sofa sleeper but where to find one. We needed a queen size/ We searched all the stores and where I had seen onr at our Sleep Country store they had now discontinued them. We were recomesnded to another store but they did not appear to have them either. So we ca,me to Amazon, they did not have a huge selection but the one we chose had a 4.5 inch mattress which was excactly the right sixe for the bed. When it was delivered we were very pleased with the look of the mattress. It had a cover on it that was waterproof and it looked as if it was very sturdy. The first to try it were our two granddaughterss who said it was fine. Thank you Amazon.
