Upholstered Pvc-style covering is easy to wipe clean, and the reinforced metal base with a stable triangular structure supports daily use. Four casters allow smooth movement, and built-in brakes help keep the chair in place when you want it stationary. Overall size ranges from 28.5" x 18" x 21" (lowest) to 24.5" x 18" x 26.5" (highest), with a 220 lb weight capacity.
