Antimicrobial, Caressoft vinyl upholstery on this Caressoft Medical/Drafting Stool looks and feels like leather, but it is more durable and can easily be cleaned with a damp cloth. Long-lasting upholstery covers a 4" thick, molded foam seat (16" diameter) for extra comfort and support. Easy-to-reach, gas lift lever for seat-height adjustment offers a vertical range of 6" from 28" to 34". The 20" chrome footing provides added foot and leg support. Hooded, double-wheel casters on the 23" five-star, chrome base slide smoothly on floors for easy moving and shifting directions. Armless medical stool supports up to 275 lb.
