It does not have arms like a more expensive one I got so it fits well under my desk, it's not thick, bulky, heavy and over padded like another one I got. Which I found this model which is light weight in comparison, and move very easily when adjusting your position while seated.  It's meshing but of great quality, not sweaty and hot plastic or leather that sticks o your thighs. It's not cheap looking, could fit nicely into an executive office to me. Easy assembly.  A perfect 5 star purchase for me.
