My Aching Butt

I've had my Secretlab Titan for just over a year now. When I first got it I was surprised how actually hard the seat was, I thought at the time it would eventually "loosen/soften" over time. This has never happened.

Typically, I spend 10-12 hours a day using this chair. I have tried pads, cushions, gel packs and despite all of this the chair remains about as comfortable as cinder blocks covered by burlap.

I bought this chair because I'm 6'4" 250lbs. Yet, I have to admit I'm about to dump the chair in favor of something that won't cause permanent butt damage (or nerve damage). While the chair remains good looking, it's just not worth the pain anymore. Open to further suggestions to make this iron maiden useful.
