I've purchased 2 other chairs before this one. The first was a "gaming" chair where it had a small base thin cushion and leg rest. The second was an ergonomic chair but it also had a flat cushion and the backrest killed my lower back. This chair is probably the most comfy with a thick cushion. It is big-friendly meaning if you're wider on the bottom it'll fit on the cushion (verify the weight limit before you buy). The arm pads feel so supporting of my elbows. Last but not least the back pad is very cushiony and is great for long hours. Highly recommend!
