I want to start my review by saying I bought this chair yesterday and it was delivered today! Extremely happy with the fast delivery and assembling the chair was simple, didn't need the instructions. I've now been sitting in the chair for over an hour and I feel supported, cushioned and comfortable. My previous chair was below ordinary, so I'm beyond glad I upgraded! I sit and work for long hours each day, so the fact this chair covers 8+ hours was a must. I'm relatively tall at 175cm and would be nice if the back rest was a bit higher, but still quite supportive. Highly recommend!
