"It has the features of a premium chair, but the ergonomics and longevity of a sub-$200 one."
The 'Upgraded Widened Linkage Armrest' means the armrests are attached to both the seat and the back, so they tilt when you recline. It also means you cannot adjust their height or position independently, which is a major ergonomic compromise.
This chair is for a buyer whose budget is firmly under $200 and who prioritizes the 'racer' aesthetic and a checklist of features like a footrest. If a wide seat base is the primary need and adjustability is secondary, it fits the description.
Anyone spending many hours a day at their desk should pass. The non-adjustable armrests are a deal-breaker for true ergonomics, and for the same price, a basic mesh office chair from a reputable brand will offer superior support and longevity.
