I received the GASEE brand Ergonomic Office Chair as part of a reviewer program. This chair took less than an hour to put together at a leisurely pace. The instructions were adequate, but there are not that many parts. It's mostly intuitive and experience in having to put stuff together. The seat cushion feels acceptable, but the back and neck supports feel rather flimsy. I think the mesh doesn't really deliver on promises for relieving spinal pressure or lumbar support, either. Hubby is a big guy and if he puts his weight into the arm rests and pushes off, they bow out. Meaning they strain under his weight. In a better chair, an armrests would not move or budge one bit.
It's not a bad chair, not an amazing chair…..it's an okay chair at a fair price.
