So far we like the mattress. Perfect for side, back and stomach sleepers. It's medium firm, but not so firm that we are sore. The only reason for 4 stars is because the sides tend to be a little less strong than our previous mattress, but we knew there was a chance of that when we bought it. Overall it took it's shape well after the recommended 48hours.

Very nice well made & comfortable 12in full size gel memory foam hybrid mattress. The mattress arrives in a box with air tight packaging, once you release the mattress it will take up to 24hrs to fully expand to its normal regular which is 75” L x 54” W x 12” thick. The mattress has a good look & design with dark blue borders with gold/yellow trim detail & a white soft comfortable firm mattress top that is a hybrid memory foam & density foam material. The mattress is definitely comfortable to sleep on with a good nights rest, the current price listed is a fair value for this full size & thickness.

We ordered this mattress in a full size for our guest room. The height of the mattress is a good size and worked well on the bed frame we have without a box spring under it. The mattress is a decent thickness and has a very comfortable cushion top. Although you normally have sheets on the mattress, it does look very nice when there are no sheets on the bed. We have had a few guest sleep on it so far and they have all said it was very comfortable. For the price this is a very good mattress and should last many years. The only thing I would add to the mattress is handles. Other mattresses I have owned had handles to make it easy when you need to move or adjust the mattress on the frame. Our mattress did not have any handles. Overall I am very happy with this mattress and I am glad we ordered it!
