The need to have x-ray, lights and services in the correct places relative to the patient is paramount for efficient treatment. The Shifter Base is a low profile device that fits under a conventional chair so that it can be moved away allowing other equipment to be moved into place. These devices may include wheelchair platforms, recliners or trolleys. The Shifter Base moves easily across the floor and will raise and lower the chair. Great care has been taken not to compromise the stability of the dental chair.
