Despite the warnings, I purchased this mattress for a family member going off to school We didn't unpack it for 3 months but when we did we were very happy with it. It was fine for about 60 days, then it started leaking... no apparent holes or tears... and now, it won't stay inflated at all. It's an expensive temporary sleep solution. We'd have been better off to just buy a low-end box springs and mattress or a futon and mattress, which is what we're doing now. It's too bad to have to dispose of this. I hate the idea of yet one more thing going to the landfill!
