Also: I'm not the most handy guy, but I built a quality riser, tossed carpet on it...and I spent less than 175 bucks. Wasn't hard.
No I actually ended up getting the Bolt xs400. They are the smallest chairs I could find width wise and I had some constraints in my room. Let me tell you they are awesome! Very comfortable, and really nice build quality. I have been super happy.
I believe HTMarket sells a riser so check their site. There are also a few others I've seen online just can't remember where.
