Completely awful for me
I'm 235 lb with "no butt," as several people have told me. Thanks to another reviewer, I now know this is because I have always had such terrible sitting posture that I sit on my tailbone and lower back. Now I practice good posture in my office chair, but have tailbone pain after an hour or so. Except, with this Purple cushion, that goes down to half an hour.<br /><br />A couple of minutes after sitting down, the back of the cushion is completely flat. It's exactly as hard a surface as the cheap flattened foam of the chair. It actually does other things to that area I can't even politely describe.<br /><br />You know what never stops being comfortable? A couch cushion! Maybe I should just pull one of those off my couch and perch on it higher than my desk! I guess I'm going back for the firmest memory foam model on here.<br /><br />Glad to know to avoid buying a Purple mattress, since this is exactly what tops them off.
