Transitional Style Thera-Glide Safety Glider by Optima Products Inc. has a patented auto-locking system that prevents gliding until a patient is safely seated and secures the chair at the optimal angle for safe egress. The glider features a 22-inch wide seat that can be adjusted to different heights and a 350-pound weight capacity. A lock-out lever is located at the rear of the chair to disable the glide motion.
