Great, but critical flaw for wheelchair use.
We tried the Purple mattresses out at a Mattress Firm, so I was kinda familiar with the feel.  Great cushion, but the problem is for those who want to use this in a foldable wheelchair or other fabric &#34;seat&#34; with no support underneath.<br />I'd been using a conventional foam cushion the past few weeks, with a hard plastic base underneath the cushion to keep it from sagging in the middle. My plan was to slide the base under the Purple cushion inside the cover.  Great idea, but the cover/case is designed with a zipper only going halfway across.  (One folds the Purple to get it in the case, and unfolds it once inside.)  It is IMPOSSIBLE to get any 16x18 base inside that case.  (My solution was to slide the Purple into the case I was already using, replacing the foam.  It works, but is not an ideal fit.<br /><br />PURPLE, if you read this, you're alienating a large base of potential clients!!! Fix this!!!
