Input: Just a great item. However there are approximately 5 length-wise seams on the bottom to create stability. After two months, one seam "disappeared, and now the bed rocks, because there is one large air space.I can probably live with it, just have to put some towels, whatever to stabilize it.
Output:
Negative
