Removing your chair's wheels accomplishes a number of tasks: The alteration shortens the chair so that it better meets the height of a low table or desk; it limits the chair's mobility, which may be bothersome if your wheeled chair slides around on slippery floors; and it also changes the chair's appearance, giving it a less utilitarian form. Most wheeled chairs roll around on casters, which are usually connected to a chair's legs by a stem inserted into a hole in the chair's leg but are sometimes attached with screws.
Turn over your chair so that the wheels are facing up. This allows you to easily access the chair's wheels for removal.
Twist one of your chair's wheels to determine whether you can twist it off. Some casters have threaded stems that are easily attached and quickly removed. Completely screw off the wheel if it has a threaded stem, and then repeat the process for all the other wheels; otherwise, move on to another method.
Drop a pea-size dot of multipurpose household oil onto one of the chair's wheels where the wheel meets the chair's leg. Get as much as possible into the crevice where the caster's stem is inserted into the hole in the chair leg. Repeat this process for the remaining wheels.
Tug on the chair's wheels until you pull them out of the chair leg hole. If your chair's wheels don't easily pop out, pry them off using your pry bar. Meet any continuing resistance with a light tap of your hammer on the inserted pry bar.
Turn over your chair. The chair's wheels should face you and be easily accessible.
Unscrew the screws holding the wheels to the chair legs.
Remove the chair's wheels.
After removing the chair's wheels, examine the underside of your chair's legs. If they look rough or jagged, don't use the chair on floors it could scratch unless you attach gliders over the rough areas.
