OYT King Size Mattress, 12" Inch Firm Gel Memory Foam King Bed Mattress in a Box with CertiPUR-US Certified Foam for Sleep Supportive & Pressure Relief,Cloud-Like Experience

No more back ache-better than anticipated-was a bit skeptical but absolutely the best matress. OYT for the WIN. Caution-this is a very heavy mattress when delivered. But worth every ounce of comfort.

I have severe musculoskeletal injuries that pain me most at night. I was told to upgrade to a firm memory foam mattress, and I am not too disappointed!This mattress offers all the pros of big-ticket mattresses for less. One con is that a month into owning it, it IS starting to bow already where we sleep, so watch out for that!

The mattress was not firm. My wife who is slenderly sunk in comfortably, but I am a large man and it gave in too much I felt as though I was sunk in 5 inches.It was soft enough that it was difficult to get out of the bed.
