We love this mattress. It is very comfortable and so much like a regular mattress we forget it came in a box. I especially like the reinforced edges as we were used to a memory foam mattress that sank if you sat on the edge. We have been very comfortable. If you want a memory foam mattress but like us need it to rebound better and be firmer this is the one!

This is definitely the product I needed; it arrived exactly as expected, matching the images in the description perfectly, and it's quite comfortable—practically a 10 out of 10. I didn't have to wait as long as with other products for the product to return to its original shape after unpacking; it practically happened in seconds.

A bed in a box? A bed in a box!!! I upgraded from an old traditional mattress and box spring to this 14-in ultra extra firm queen mattress... Let me tell you, I am very well pleased and shocked at how amazing this mattress is! I will say, when they say extra firm, it is firm but not like sleeping on a board. The firmness is perfect for my liking and gives me confidence and satisfaction that this mattress will last for quite a while! I probably should have gone with the 12-in due to how tall this mattress is and if you have a sheet set, take into consideration that if you tuck your sheets in like us Gen Xers were taught, you will have less sheet towards your pillow area. The 14-in is just a tad bit taller than my old traditional sleeping system but I also bought a bed frame with 8-in of clearance underneath the mattress so that did make the bed look very tall. I couldn't be happier with this purchase and I highly suggest at this price point, others to try it! I believe that you will not be disappointed and will be writing a 5 Star review just like this one!

Purchased for my Dad. It’s definitely firm and takes atleast a day to fully form. You must purchase a box spring and rail for this mattress.

I am very picky about my back support! This mattress is over the top why haven't I done this before in stead of the 1000+ dollar ones!! It meets all my qualifications. Remember it should lie on bet for 2-3 days before use so it fully expands.
