I've had this mattress for two weeks after purchasing it in store with the help from the sleep machine (it was on the recommended list).
I am waking up with back, shoulder and hip pain and feeling so tired, it's just not comfy at all. In fact, after the first couple of nights I was wishing for my old 12 year old mattress back! Never had back or any other pain from a mattress before, but we bought this one as my husband was suffering lower back pain with the previous mattress, and as it was old we knew it needed replacing. He finds this mattress comfy and now doesn't suffer with lower back pain like he used to, but agrees that we can't keep a mattress that is causing me so much discomfort.
Really don't think I can wait 30 days until I can replace it.
