Can't comment on durability but mattress was what I expected. 6-7 on firmness, lacks edge support (as all foams do), good mobility and contour without feeling stuck. Customer support was not so great in resolving or even responding to questions.
We purchased the Ghostbusters mattress to replace a very old mattress. The sleep I get is a deeper sleep. I can sleep longer in bed and I feel better all over, no more back ache from sleeping. The mattress just conforms to me.
Well we gave had it for 25 days now. It is great, but my husband and i were really expecting something a little softer. This is a very firm matress. I know the firmness varies by your weight. I am 128 lbs, and my husband is about 190. We are not in love with it yet. Im hoping to love it by the end of our 100 days. I dont want to go through hassle of returning and shopping for a new one. All the reviews saod they were immediately in love. It was not too good the first week, it starting getting a little better after that. Im not sure yet if we will keep it or not.
My wife and I were waking up every morning with cronic back pain, since we bought our ghost bed the sleep quality has been amazing and the back pain is a distant memory
