Pleasantly surprised!!

I was skeptical ordering a box mattress especially online. I ordered hoping it would live up to its description. It came earlier than expected and set up was easy and smooth (no weird smell which is often mentioned in these reviews). I have it overnight plus some since it's a guest bed. It is so comfortable!! Definitely firm but a nice soft top layer keeps it from being a brick! I am impressed by the value and comfort. I don't have an opinion on durability because being a guest bed it will only be rarely used.

Love it!

Day 3 of having this mattress and I absolutely love it! Best sleep I've gotten in a very long time. I had back pains and this mattress definitely helps with that.

A nice comfortable mattress with cooling foam.

This mattress is quite comfortable and feels supportive. It appears well-made, and I really like the cooling gel memory foam it has, as I live in a warm climate, and that really seems to be good for better sleep. It was packaged well and arrived quickly.
