Memory Foam Sofa Mattress (Full)

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.

We replaced the old mattress that was original to our motorhome in the fold out sofa bed. Our adult son and his girlfriend slept on this for a week while we were on vacation and continued to say how comfortable it was! We are so happy with this mattress, it took shape quickly, doesn’t smell and folds into the sofa when put away. I would highly recommend this!

I arrived home after a busy day and my new hide a bed mattress had arrived at my doorstep. I opened the box immediately to remove the mattress and used the handy cutter that came with it to slice open the bag without harming the mattress. I didn’t remove it from the plastic bag because the mattress is for the hide a bed at my camp but I wanted to see how comfortable it was before lugging it 80 miles up there. I noticed that it inflated to size moments after slicing open the plastic bag, it measured over 4” when I checked. I decided to put a blanket over the plastic and then laid down to test its comfort, two hours later I woke up; I didn’t mean to fall asleep! It definitely passed the comfort test on my living room floor so hopefully it will be as wonderful on my hide a bed. You get a full size hide a bed memory foam mattress in the box with a removable, washable cover that zips, and a safety cutting blade.

Have an older sofa bed I keep in the TV room for when I have overflow guests. Original mattress (innerspring?) was basically shot (and was really uncomfortable from day one). Was searching for a replacement mattress and saw this one on Amazon...thought I'd give it a try. Unpacked according to directions provided and let it 'expand to full size' for 3 days. Installed it into the sofa. On the mattress support 'frame' on this couch, there is a slightly elevated horizontal metal rail that holds the head of the mattress in place and a heavy 'U" shaped bracket at the foot that keeps the 'foot' of the mattress in place. I think the original mattress may have been 72" long and this mattress is 73" long and it makes for a 'snug' fit. I bought a mattress protector/cover for the new mattress as well as a set of sheets (both were 'specific' to the dimensions for sofa-bed mattresses). With the mattress pad and sheets 'on' the new mattress, it is a little 'thick' and I have to make sure the head of mattress is in place or it will not retract into the base of the couch. So far, so good...just waiting for the first opportunity I get for one of my 'guests' to try it out.

The mattress foam was 4 inches on the side and 3.5 on the top and bottom. Still pretty good replacement for our old mattress.
