I put this chair together myself without help. Extremely comfortable. it's stable and adjustable.

I love the DX brand for its quality and price. I purchased my original DX Formula chair back in 2013 and the chair is still in outstanding shape but the chair lift portion would gradually lower the chair on its own so it was bad after a decade of heavy use. I'm sure I could have purchased the part to keep that chair going another several years but opted to purchase the newest Drifter series model. I love the new Drifting series design compared to my original Formula chair. The build quality is still as solid as my original chair with some design changes that I think are well thought out to improve the chair design (e.g., adjustable arm rests). I'm loving my new Drift series chair for overall design, comfort and competitive pricing you can't beat for the quality you get. Sure I could have gotten a $150 chair that would likely fall apart in 2 years but I opted to stay in the DX family for the quality I expect where my chair lasts 10+ years!

Just by looking at the quality, I know I won't be disappointed with this chair.
