Kingsdown Body System Mattress Review

4 years ago I purchased a Kings Down bed (well over the amount I budgeted for) because I fell for the whole schpeel! Come lay on this, here's what I would recommend, ita has a lifetime warranty, blah, blah, blah! Well now that I have problems the lifetime warranty dropped down to 10 years, but the kicker is Kings Down allows itself 2" for the mattress to sink!! So when you are only at 1"..."keep an eye on it and call us when it starts to sag more!" Are you kidding me?! 2" is constantly rolling into eachother in the middle of the bed, 2" is always waking up with back pain, 2" is never feeling like you slept a full night, 2" is TOTALLY NOT WORTH THE MONEY!
