Chair is amazing. Set up was easy. I weigh 140lbs and it's perfect for me. It came with extra screws. Support is firm but comfortable. Plastics on the chair are 30% glass fibre which make the quality quite impeccable. The base is all metal. This is perfect for hardwood or tile floors (basically any hard surface). All the bolts has brass fittings (not screwing metal bolts into plastic like some cheap chairs) overall, I'm happy with the chair even with the higher price tag.
