I've had this mattress for 3 years and I'm already in the market for a new one. I have fibromyalgia and I often take almost an hour to fall asleep on this bed because of how uncomfortable it is. Also, my legs and arms sometimes fall asleep because you sink too much into the mattress. I regret buying this mattress because now I'm already back in the mattress market, these things are too expensive to be replacing them this often.
