Preface- We replaced our current memory foam mattress because it was too firm. The mattress as stated is rolled into a tight package that takes two adults to carry (upstairs) . We got the purple plus, so it has 2" of additional foam. Even with an additional 2" of foam this mattress was still thinner than the one it replaced. Bottom line is that I sleep better, albeit I am 230 lbs and a bit too heavy for this mattress according to reviews I read. No more hip pain. On the down side the outer edges have little support, so it is difficult to sit on the edge of the bed without sliding off.
