If at all possible, try to visit/sit in a chair before you buy it. I probably would've gone with something different if I'd had that option.
I used a $99.00 chair from Frys for probably 10 years. Replaced the base/strut due to wear. Replaced the seat/arms due to wear once. It had flip up arms, which were great for playing guitar. Chair was good until I started working from home, spending 10-12 hours a day in it. After a while it started killing my lower back.
After a lot of research I went with a Secretlab Titan. Upsides, it's comfortable. Seat is big enough that even though the arms don't flip up, I can shift a bit sideways for playing guitar. Downsides, there is zero friction adjustment for reclining. It's like sitting on a knife edge where if you lean back quickly, you're going completly back with some velocity. To the extent that initially I had a fear of tipping the chair over backwards. Big downside, their support is some of the worst I've ever dealt with.
