Bought for my 3 yo. He sleeps great on it. So far so good. Others said sometimes it didnt fully "inflate" but we did not have issues. I have laid on it with him and it is quite firm. After laying for a while you can feel the sinking in effect from the memory foam. I would say it would be more comfortable if you are someone who doesnt change positions much during sleep or are lightweight (ie my 3 yo).

Decided to try out this mattress in our camper van. It was easy to open the box and pull out the mattress and roll into place. By the next day the mattress filled in and perfectly fit in the van. The first night of using the mattress it was a little hard at first but I believe that was because of the cold temperature in the van. As it warmed up with us laying on it, it became very comfortable. The mattress allowed a great nights sleep, and it did not smell like many prior memory foam purchases.

The mattress never fully expanded to 10inches. I waited a couple of weeks b before getting back to Zinus and Sams Club. Neither was willing to do anything about it It is in a remote cabin location so maybe after more than a month it has fully expanded but I won't be up their for awhile.

This mattress is just what we needed! The support our bodies need with just enough give to allow comfortable sleep to tired backs, hips and shoulders. We love our new mattress! Customer service support for questions was available and very helpful during set-up, very easy to unbox and just watch it decompress! This was a very easy process that made the purchase of a new mattress very doable for us and getting it in our 5th wheel without any issues. Not for traveling, too heavy.

A very comfortable mattress with good back support. I'm very pleased with the purchase and highly recommend it

We’ve had this a few weeks and the smell won’t go away! I thought it would air out but the smell hangs on.

This offers great support and comfort. It was not too firm or soft, sort of a goldy locks- JUST RIGHT.

I bought this mattress for my 18yo daughter. It took about 3 weeks, rather than 3 days to decompress and the corners never expanded to the full 10".

Never inflated. This is the 4th mattress of this type. All the others have been great. After 4 days, it was a lumpy mess.

My daughter raved about this mattress, so when I needed a new one due to back problems, I purchased it on sale at Sam's Club. It was a little slow to arrive, but when it got here, we unpacked it the same day. The bed expanded beautifully. It is just the right firmness for me. Right now I have a spinal disk problem with sciatica nerve pain. It's very comfortable and gives me just the right firmness and support. Thank you Zinus and Sam's Club!
