A-dec 400 Dental Chair
Combines contemporary styling with robust construction
Contemporary, versatile, strong
The A-dec 400 dental chair combines robust construction, contemporary styling, and left/right versatility with a Radius delivery system.
Comfort for your patients
Put your patients at ease. The virtual pivot synchronises movement with the natural motion of the patient. The toeboard tilt provides the patient with comfortable lower leg support. Together, they create a cradling effect for the patient.
The key to productivity and career longevity is remaining comfortable while you work. This is why A-dec 400 is designed to keep your movement fluid and ergonomically aligned.
The Radius delivery systems, cuspidor, and assistant's instrumentation quickly and easily rotate around the chair for complete left/right versatility.
