  • I love this Mattress so much!!!
Color: Grey Size: King Set name: 14inch Firm
As someone who has Chronic Degenerative Disc Disease and also has Severe status in my L3-S1, having a Spinal Discectomy and a Laminectomy all within 3 years of each other, I was sleeping on a memory foam mattress and it was making me feel absolutely miserable until I got this Mattress. The first couple nights my body needed to adjust to it but it was actually correcting the wrongs from years of sleeping on a Memory Foam. My back pain has started to reside and I can tell it is because of this product. Amazing Price for Amazing Product. Top Quality for firmness, comfort and design. ... show more

  • Great price! Great mattress!
Color: Grey Size: King Set name: 14inch Firm
It's very firm, but not so much that side sleeping becomes uncomfortable. I haven't gotten uncomfortably warm like I did sleeping on my last mattress. I'm used to turning the heat down at night because I get so hot. My second night with this mattress I actually woke up chilly and had to turn the heat back up a little. You will definitely feel like you are laying on a mattress that cost four times as much! ... show more

  • Firm in middle 2/3, outer edge 1/3 collapses
Color: Grey Size: King Set name: 14inch Firm
It is a nice mattress. In the midsection, it is semi-firm. It collapses under pressure on the sides. I am 152lbs. It collapses 4-5 inches if I sit on the edge of the bed to put on shoes, take night medicine, drink water, etc. I will not be able to sit on the edge. The mattress will slope in time. Sleeping closer to the middle is comfy, though. ... show more
