Quality is excellent. Worth the price. Assembling is easy. Headrest is good.

The height and tension adjusting on the chair works great, I found the exact perfect spot for someone my height and haven't had to adjust either of these since, very happy with this! The armrests are incredibly durable.

Honestly, I've had my dxracer since 2012. a while back the mechanisms for my chair was still broken and I'm still glad that the dx racer still provides these parts because I get to enjoy my chair with just specifically big and tall! I can only hope that my chair continues to stand the test of time and then take racer continues to have these accessories as they are top quality!
