Not sure where to begin. The delivery was great, the unboxing went very well, the comfort level is ideal, heres my problem with this mattress..I bought it because it says its firm, and weight limit was 750 pounds. Also it said it use to sell for over  2500...The VERY BIG problem I have is the sides of this mattress has no support at all. My husband was injured back in 2012...due to that his legs have very little strength in them . Thats caused SERIOUS weight gain. When he sits up in the morning and proceeds to sit on the edge of the bed it crushes down so hard it almost makes him slide out of bed. Im so worried he will and I will have to call the fire department ro help him off the floor...so I likely will return it...If youre around 200 lbs this mattress is very comfortable..its not hard. Weve slept in just 3 nights..was hoping it would improve...hope this helps you to decide what to get.
