Parsons ADL's own "Soft Top" Transfer Discs incorporate a 1/8 in (0.3 cm) soft but durable neoprene, non slip pad top and bottom to ensure user comfort in either socks or bare feet. The rotating action is similar to a "Lazy Susan" but uses graphite pads instead of ball bearings. Weight capacity is approx. 300 lbs. (137 kg).
