I bought this chair for working at home. This chair really relieves the pressure points I was getting in my tailbone and lower back.
I find it's a bit easier to concentrate with my back being more comfortable, and I dont get antsy so early in the day from sitting in the same place.
The seat can be a little hot, and I am an extremely sweaty person who likes to wear shorts, so I covered the seat part with fabric and it's perfect. The seat does tip forward if I creep right up to the edge (like when I'm too lazy to get up to grab something that is just put of my reach. No big deal tho.
All and all, excellent purchase.
