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,

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. If you're looking for parts, the links can be found in the FAQ question: "If my chair's warranty has expired and I need to purchase corresponding parts, what should I do?"

The lumbar support is so convenient to be able to adjust the level of support with just a simple turn of a knob.
