This bed features grounded, full electric head and foot adjustments as well as electric height adjustments. The steel frame is incredibly strong with a 600 pound weight capacity, and the widely arched legs are great for getting wheelchairs and patient lifts right up to the bed. The bed is "Roll-In-Low", which means that it only rolls when the bed is lowered to the floor. When elevated the bed automatically locks and will not move. This is ideal for home users who rarely move the bed. The bed has 4 casters, two of which lock.
