Very easy to assemble. The seat cushion and neck portion are very comfortable for sitting extended periods of time. It rocks back and forth which is another comfortable feature.
im ~240lbs. after a week of use it feels solid and stable; rolling around and leaning back etc. the vertical arm rests are a key reason why i chose this model. they lift a bit on the stiff side but better than too loose. bonded leather feels good & durable. solid support for long study sessions at my desk (literally most of my neck/shoulder pain has departed)! assembly & instructions were easy 30min with unboxing. the plastic wheels i replaced immediately with my old rubberized ones for hardwood but thats pretty standard issue. all in all it's a great chair and im grateful to have it!
