[EDITED - 3 Year Review!] I didn't do the egg test, but...
[EDIT] 3 year review - This thing has been saving my butt every day from pain for almost 3 years now. I literally would not be able to sit in my chair longer than 30 minutes if it wasn't for this cushion. I've spent LONG nights working/playing games in my chair, and I haven't had a single issue with back/bottom pain.<br /><br />Review upgraded to 5-stars, because this thing has paid for itself every day for the last 3 years. The fabric cover is still holding strong, and the rubber cushion underneath is every bit as comfortable as it was on day one.<br /><br />Bravo, Purple. You've got an awesome product here.<br />----------<br /><br />I just got my Ultimate seat cushion today, and have been trying it out over the last few sessions at the computer. I didn't feel comfortable doing the "egg test" so I went with a pack of cigarettes, since that was the closest thing I had readily available that was light and flimsy. The cigarette box did not get crushed, and I'm 300lbs. That was pretty remarkable in my opinion. Ok, on with the review.<br /><br />I have been using a pillow as added cushion for the last few months, and I would always have aching pains in my lower back and buttocks after sitting for more than an hour. So far, this cushion has solved that problem. It feels great, and I feel like this was money well-spent.<br /><br />I plan to add to this review later on, so I will save the pros and cons for then. I gave it 4/5 stars today because the cover slightly ripped at the end of the zipper (which feels really flimsy). This doesn't cause any malfunctions, but it's worth noting that it ripped when I was simply putting the cushion into the cover, as per the HUGE instruction sheet.<br /><br />[To be continued]
