We purchased this bed only one month ago, and it is already sagging. Nice if you like/want a very soft bed that sinks in like a hammock. However, do NOT purchase this bed if you need even minimal back support. From reading the reviews, lots of people like this bed. I'm guessing that the quality is inconsistent -- sometimes the beds are good and sometimes they are not. It's up to you whether you want to gamble. We lost our money on this gamble; we'll have to replace the bed due to waking to severe back and neck pain.
