I've had this queen set for less than 2 years. I have fibromyalgia, so chronic pain is an issue. When I purchased this, The salesman said that this was second only to the tempurpedic, which was such a different type of mattress, i was reluctant to buy. I am in chronic pain BECAUSE of this bed. It sags SO badly, the only place that doesn't (yet) is thevery middle.
I had never before spent SO much for a mattress (an especially huge expense as my only income is social security. I feel extremely taken advantage of. I would not recommend this bed to anyone!!
This is the first "premium" mattress I had ever sprung for. It is the most uncomfortable mattrress i have ever had!
