Things You'll Need
Swivel chairs can be convenient if you need to switch from one desk to another or if you sit down and get up frequently. However, if the swiveling is becoming a problem, you can adjust the chair to prevent it from turning. Keeping a swivel chair from turning requires a few basic tools.

Inspect the base of the chair. Swivel chairs work differently depending on the model. Look for screws at the base that can be tightened or a swivel lock that can be engaged to hold the chair in place.
Tighten any screws or brackets on the base of the chair or at the bottom of the stand to see if that impedes the chair from turning. This will be enough to stop most chairs from turning, but others may not have the option.
Fit a small rubber wedge under the chair, between the base and the swiveling pole. Hammer the wedge gently into the base so it creates a seal between the chair's base and the pole it sits upon. Don't hammer too hard or you could damage the chair. The wedge will cause friction and will limit the chair's range of motion.
Wrap tape around the chair's pole and the wedge, if the wedge won't stay in place by itself. One wedge should be enough to stop the swivel, but add a second on the opposite side of the pole if needed.
