Goes flat. Yea, they don't tell you that.
This thing is supposed to withstand over 300lbs. I weight 250 and loved it at first, but after I used it more and more it supported me less and less. Looked into maybe a warranty of some kind and it turns out that the warranty doesn't cover any "natural decompression or adjustment due to everyday use." The purple cushion goes flat, y'all. Its just like using a squishy memory foam cushion at this point, except it cost 4x as much. Sorely disappointed.
