I have been sleeping on this mattress for about 3 three weeks and I give it two thumbs up. It's very different from a plain foam layered mattress. I had to get use to the coils because when you lay on the mattress you can slightly feel the coils adjusting to your body shape, which is great because on my old mattress I experienced hip pain when I slept on my side but not with this mattress. Also, I have gone to bed with back pain but did not wake up in pain. I am pleasantly surprised with how soft but firm this mattress is, it's a winner.
