I bought one a week back from a shop here in Vashi that has just office chairs and furniture. Paid ~5.5k. Not the most stylish nor is it made by some super brand but its very cool.
It has a high backrest going all the way upto my head when sitting. Hydraulic (standard in almost all chairs) and it goes up enough to squeeze my legs between the chair and table
It reclines back more than most chairs I've seen but the most killer feature on it is the backrest locking mechanism which means you don't have to push yourself constantly or shift your weight to keep the seat in that position. I have the backrest locked into a fairly upright position while browsing and generally working on the PC, a little more reclined while playing games or racing
and when its time to watch some movies or TV eps, back goes the seat fully like a car/airline seat (or better
). The seat also points up a tiny bit so you can place a stool in front to put your feet. You can actually fall asleep on it and I have have!
Make sure your chair has the backlocking thingie! It's pretty awesome!
