  • Get it-you won't regret the purchase!
Item Thickness: 12.0 Inches Size: Full
I shopped around for almost a year for a mattress. I found this one had all I was looking for-hybrid, no chemical smell, medium firm and solid reviews. I am so glad I waited and found this one. Unpacking was easy. I had read warnings about mattresses suddenly almost exploding out of seal, but it was very well set up. I had to do this alone -71 year old woman with many spinal issues. Once you use the included cutter it slowly hisses and expands in a controlled way. And most importantly the mattress is the best melding of firm and cloud like softness. For the first time ever my varied areas of arthritis are all happy and I literally don't want to leave the bed! Get it-you won't regret the purchase. ... show more
