Have had this chair for over a year, not worth the money I paid. The foot rest broke after a few months, and the height adjustment worked for maybe 6 months. Very hard on my back too. The seat is crooked, no matter what I do. It always leans, and is super uncomfortable. Also now whenever I sit on the chair, it makes a huge bang sound, no idea why. The wheels are cheap plastic, and don’t roll very well. Arms are always loose, even if I tighten them. Save your money and don’t buy it. Wayyyy overpriced. You’d think a 400 chair would last over a year, but nope.
