This mattress is not 12 Inches. It is only 10 Inches. At first I thought it just needed to fully expand but it's been 16 days and it has not changed. It is still only 10 Inches thick. It may be that the wrong one was shipped but if that is not what happened then this mattress is not what I expected.

I personally would not buy this one (ever...). I cannot sleep. It's way too firm for me. I had a foam mattress, and then a box springs and regular coil mattress. They were both more comfortable. I feel like I am sleeping on the floor... I am not sure what to do at this point (as I've already bought it and it's in my home!)

I have been using this mattress just over a week now and am really pleased with it. we were skeptical of a mattress being compressed into a box but this is truly amazing. One of the best mattresses I've ever slept on. Hope it holds up, but so far very good.

I bought this mattress for my son who lives far away. He works two jobs and only catches sleep here and there. I sent him this mattress sight unseen with the frame. He sent me pictures of each stage of him putting it together. The fact it came in a box had me scared I had made a mistake. It unfolded beautifully. He let it rise for 6 to 8 hours. Then he had the best nights sleep he has had in years. And continues too each night there after. Best present I have ever given someone. I highly recommend this mattress. Comfortably firm mattress that holds it shape.

This is a very good FIRM mattress. The family is happy as we bought two. Be careful when you release it from the plastic wrap. Be sure you are not in the uncoil path. The only thing I would like is for it to have a stiff edge which makes it easier to get in and out of bed. Great price!

For the price this is overall a great mattress, is has sub-par edge support (if you sleep near the edge you will fall), but I am about 235lbs and have lower back problems and this mattress is COMFORTABLE. Not worth spending money on a name brand mattress when there is quality like this out there for hundreds of dollars cheaper.

Extremely comfortable.

a lot of loose material. does not lay flat/smooth where it was rolled.

This my second night sleeping on it , so far very pleased with it

The bed feels so good. It was a great purchase..
