Overall this chair has been nice. The wheels would be better if they were the rollerblade wheels. Also the material is coming up around the edge and looking to exchange for a new chair.
This chair is not flimsy - there is actual metal ! Adjustable arm height is great for various locations (I use at both desk & sewing table). The lumbar support is a life saver. The mesh keeps it from getting hot. I'm very pleased with my purchase!
