On the one hand, the first night was the best night's sleep in memory and the nights since have been pretty good as well. My wife has chronic pain related sleep difficulties and this mattress has helped. We routinely sleep with two labradors on the bed and it has supported us all well. However, I am concerned about the durability as it has already developed significant dents where we sleep with a pronounced peak in between despite our rotating the mattress after only two weeks. I followed instructions and aired it out for 48 hours before sleeping on it (smell issue mentioned in other reviews was very minor). As always, the Overstock price and delievery was excellent.
