Given the price of this mattress I definitely had my doubts. However since my husband finally agreed after 6.5 years of sleeping in a full size bed to finally get a king, I thought "well if we atleast get a bigger size we can upgrade to a better (read: more expensive) mattress in a few years. However I forsee us keeping this mattress for years to come, we both love it and have been sleeping great on it for several weeks now. I am getting up in the middle of the night for our newborn baby and my husband can't even feel me getting up out of the bed and when I get back into bed I am falling asleep quickly and not wasting precious sleep time trying to get comfortable.
