What chair do you use?
 

I'm developing bad posture from long gaming sessions. I'm using a cheap chair and my ass starts feeling uncomfortable after a while. I need to invest in a decent chair.

The only way I can avoid posture related pain is by going to the gym.

Standing desk for the past year and a half.

Solid oak half back office chair, circa 1933.

I've used this chair for last 2-3 years... not bad but it is big... on sale now.

Herman Miller Embody. It shapes you into the proper form. PAINFUL at first but I haven't had a single back issue since. Best money I've ever spent.

Damn! Now that's a chair! Maybe in a couple more years I'll be willing to dish out that kind of coin, I can see how it would benefit for the course of your life, but it's such a massive up-front cost...

I don't even use a chair anymore , I have a really bad back and I never found a single chair that actually didn't give me some sort of back pain or another. I started to use an exercise ball one day and now I sit cross legged on it most of the day while on my PC I haven't had back pain since, I think it is because I am moving most of the time.

Really great

Mine is a very minimal office chair. It's pretty short (doesn't quite put me directly under my desk) and the lumbar support keeps slipping out. I definitely need a new one, but I can't fit a comfy recliner in my room. :\
