Essential Ergonomic Office Chair with Headrest & Lumbar Support

Cannot sit in this all day

I'm sorry but I wanted a new chair that would help me sit for 8 hours while I work but this isn't it. The arms, the back, these are great but the seat feels like Im sitting on brick after a couple hours. Not enough cushion or shape to support or something but I cannot sit in this chair all day, it actually hurts worse than my old chair that I was trying to replace.
