The screws are not long enough, especially in the top back cushion where most of the back and forth will occur

Seriously, and for short people the little extra cushion at the knees is super comfortable, and it will help the circulation I think as I sit.at bottom level, my feet just touch the floor, the way I like, i'm not shrunk down, and at maximum height, I can't touch the floor at all.the bottom where the rollers are, that piece is just as solid as the arms are, and I feel very secure in the chair

Often chairs in this price range have poor foam cushions, the seat cushion here is quality and high density

Very nice chair with pretty good cushioning.

The seat is especially nice and well cushioned.
