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.

Ergonomic design

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.

Left/right versatility

The Radius delivery systems, cuspidor, and assistant's instrumentation
quickly and easily rotate around the chair for complete left/right
versatility.
