Excellent Memory Foam Mattress I'm really happy with my 10-Inch Memory Foam Queen Mattress. The quality is excellent, and the navy blue color looks great in my bedroom. The mattress provides fantastic support, conforming to my body and relieving pressure on my shoulders and hips. The cooling feature works well, keeping me comfortable throughout the night. Setup was quick and easy. I highly recommend this mattress for anyone seeking comfort and support.

It’s perfect! We had guests over for a weekend and it worked out great. We let it expand for about 12 hours before they arrived and glad we did! It’s supportive and guests slept well. I wasn’t expecting much but I’m impressed. Also folds up into our couch perfectly.

A little too long, a little narrow, but it seems to fit and feels comfortable.

Got this for a pullout couch in my camper and it’s as comfortable as what you would expect from a pull out couch mattress. However if used as a topper on a bed I think it would add a very soft and deep layer if that’s what your looking for to sleep on.

Although it didn't fit my pull out couch (it was short on both sides by 3 inches), I believe it's because the couch is a old model, maybe early 2000's. They were kind enough to let me keep it and give a 30% refund. Its a great mattress and good quality, just didn't fit my couch. So now I have it for emergency guest use, or they said I could sell it. This is a very transparent company and I thank them for that, I wish it could've fit but at least I have options and a partial refund

I had family come from out of town and slept on this mattress for 3 nights. They loved it and said it was the most comfortable fold out bed they had ever slept on. It actually folds up easy and made the couch sit better. Worth your money. Buy one!

Fits my hide a bed great! Will be a great place for my grand daughter to sleep when she stays the night. Bought an old hide a bed the mattress that was on it was old. This is perfect! Will put a little padding on it as you can feel the bars.

It's very comfortable, a little bit of foam smell that went away after 10 min, which is normal. We ended up putting it on top of the existing couch mattress because our pull out couch doesn't have enough support to only put a memory foam. Surprisingly, we were able to close the couch with both mattresses on. Overall I recommend it.
