Milliard 4.5-Inch Memory Foam Sofa Bed Mattress Replacement for Queen Size Sleeper Sofa & Couch Beds – Premium Comfort (Sofa Not Included).

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

This mattress,saved my back.I baught it in 2023,it is still fine,I was just checking to see if it was still that great price.

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.

10 times better than the mattress that came in the queen sofa. No springs in the back and fits perfect when you close it up. Has a nice zip cover on it also. I could have bought one of the other brands cheaper but glad I didn’t. Worth the extra cost.

Wife loves it!! Says it is super comfortable!!

This new mattress is very comfortable. It's a little harder to fold into my sofa, but I am able to do it myself.It was easy to set up and the thickness is great, no more feeling the bar. The size is a little narrower than my previous spring mattress, but it's not a problem.

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.

Based upon the reviews I chose this mattress to replace the original mattress with internal springs etc, It fit fine and did not prevent the spread fan from closing easily.
