One of the worst mattresses ever. The first one i received had an indention in it like someone had worn it out. I had to crawl out of the hole in the morning Then got a replacement and it is horrible too. Hard nonconforming to your body at all! You only get One exchange so you’re stuck with what they deliver the second time. Never, never recommend this mattress. You would assume the high cost would mean high quality but it doesn't!
