Padded armrest?

[Cooler running]

Hey
I was recently thinking that most of the gaming chairs around seem to have these sort of hard foam armrests.
Would I have to attach wheels to an armchair to get this result?

Yeeah , thats why I dont use a gaming chair anymore , you might look at office chairs maybe ?

If you know some particularily confortable office chairs for under £500 I would be keen to know more. It seems that mobile chairs and soft padded chairs are two distinct categories from the products ive seen.
