So far, So great.  I switched my bedroom mattress which I paid way too much for about 10 years ago. And I can’t believe it took this long to try mattress. It’s only been about 4 days, but I have actually had more sleep, less, leg, arm and.hip pain.  I actually feel more rested. 
When I opened the mattress I had no problem with any smells I heard some may have. I will say it slides around on my box spring but I may get a bunkie board.
