My three year old mattress is going back to the store I purchased it from after countless nights of bad sleep due to major mattress sagging. I’m all of 135 lbs and for the first two years of owning the mattress I slept alone, flipping the mattress every 6 months as recommended. Of course, with my heavy travel schedule, I was only sleeping on the bed a few weeks out of each month — if that much. That should tell you just how bad this mattress is if a relatively light weight person, sleeping alone, only half the time, and flipping as recommended, experiences such terrible sagging.
