I have a rather cheap (about 90, - EUR) "executive chair-like" desk chair of Poco. After about 3 years, one of the roles has given up the ghost. Now I was on the theme replacement "and the decision hard floor-role" vs. Soft-ground role "faced. Before my desk is a flat carpet, so the desk chair is not scratched the floor as possible. That's why I chose this soft ground roles. A good choice, as has now been found. The old roles were harder and slowed down. These new roles are slightly larger, softer and unrestrained. The chair is thus a number has improved. Now I would even dare me to use the chair on the bare floor.
