This 450 lbs-capacity round rolling stool is built for professionals who move between workstations all day—dental hygienists, salon techs, lab assistants, massage therapists, and home-office users who also need to pull up at the kitchen counter. The phi 15.7 x 3.9 in / phi 39.9 x 9.9 cm round cushion is high-density compressed foam (20 percent thicker than standard rolling stools) topped with breathable PU leather that wipes clean with disinfectant and resists fading. An SGS-certified 3-stage hydraulic gas lift adjusts seat height from 21.7 to 28.0 in / 55 to 71 cm with one-hand operation—so multiple users share the same stool without moving the counter or table. The widened 21.3 in / 54.9 cm metal base supports up to 450 lbs / 204 kg without bending or wobble, keeping lean-forward tasks (detailing, tattooing, microscope, nail work) stable. Five 360 deg swivel PU casters glide silently across tile, hardwood, carpet, and vinyl with no scuff marks, so you move between stations without interrupting clients or disturbing sleeping patients. Overall footprint 21.3 x 21.3 x 21.7-28.0 in / 54 x 54 x 55-71 cm; net weight 10.9 lbs / 4.95 kg; materials leather, sponge, iron. Model MST001-W, white, counter-stool style. Color: White seat with metal base.
