I took no more than 15 minutes to put it together. The seat base, in particular, provides exceptional comfort. The chair has been really comfortable to use for the past month. Its adjustable features allow me to find the perfect position for my body,

The most comfortable chair I've owned. Several hours of working in and gaming in.

I have an older model (~8 years) and one of the wheelbase arms broke off. DXRacer was responsive to my email question and told me which base would work with my model.
