Comfortable supportive mattress for couch-bed
Size: Full
This is a great mattress for a pull out bed. Gives good support but in not hard. Is just what is needed for a pull out couck

The ultimate sofa bed upgrade! No more feeling the metal bars!
Size: Queen
Anyone who has ever slept on a pull-out couch knows how uncomfortable they can be, but this 4.7-inch memory foam mattress completely transforms the entire sleeping experience.What I love about it:Blocks the Frame: At 4.7 inches, it is thick enough to completely block out the feel of the metal support bars underneath. You get a smooth, supportive surface instead of a sore back.Folds Effortlessly: The memory foam is incredibly resilient and flexible. It bends easily when folding the couch back up into a sofa without jamming the mechanism or bunching up.Contours Comfortably: It offers the perfect balance of pressure-relieving foam that contours to your body, making a standard guest sofa feel like a high-end bed.Instant Guest Luxury: It breathes new life into an old sleeper sofa, turning a dreaded sleeping arrangement into a truly comfortable night's rest for friends and family.If you want to rescue your guests from a lumpy pull-out couch, this mattress is a brilliant, space-saving solution.

Very comfortable and worth the cost of upgrade!
Size: Queen
We paired this with the Meluisly Sleeper Support Board underneath and it turned an awful sofa bed experience into an extremely comfortable visit! I let the mattress expand for 72 hours before folding it up in the couch. I didn't have any issues with non-expansion. It doesn't smell either! It does fit and I'm able to fold the mattress up into the sofa but this is heavier than the old sofa mattress and harder to pull out. When paired with the sleeper support board it's definitely harder to pull out but still worth it for the comfort factor.

Surprisingly SUPPORTIVE and conforming while NOT like a box
Size: Queen
I would actually give this product 5 stars. but I am still getting used to this product. The mattress is FINE. Hard mattress / supportive for sure. I am surprisingly not experiencing hip soreness at all - while the top of this mattress is not really soft, but it IS conforming. This mattress is surprising me. Again, due to its supportiveness and conforming, yet not causing hip soreness at all. And I learned today that there is a softer mattress I could choose for our other hideway bed as we have two of them. One in the living room and one in our spare bedroom. I had air mattresses on them, but that has become TOO big of a hassle with air leaks. Just not looking for leaks anymore. No more being careful getting in and out of bed. I could choose a softer mattress, now that I know there are also foldable boards to put between the mattress and the foldout, but by the time you purchase the cheaper mattress (softer and the board to block the bar - may as well probably just purchase the more supportive mattress??). The harder more supportive mattress isn't so hard like sleeping on a box - surprisingly, It really is more supportive. I will get a second one of this mattress for $200. Update: have come to really LIKE this mattress. You can feel the couple of inches of memory foam on the top when laying on this mattress and moving around on it.

Surprisingly comfortable!
Size: Queen
We bought this as a replacement for a spring mattress in a rollout couch at our cabin. My 66-year-old sister-in-law and her 37-year-old daughter were both comfortable sleeping in it together for a long weekend. They both thought it was very comfortable so I am happy with the purchase!
