The EDGE O has a robust metal construction, a mobile base with 4 medical-grade castors and a rear lock, and is controlled by 3 silent linear actuators and one telescopic column with a modern multi-functional wireless foot controller. The upholstery consists of 5 separate padded parts, fully removable for easy cleaning and disinfection, made of high-density, non-deformable foam, and is abrasion-resistant, flame-retardant, and antimicrobial, and comes in a choice of 80 different colours and 8 textures. Designed for patient comfort and operator ergonomics, the EDGE O has a minimum height of 53 cm (21 inches) and a maximum height of 93 cm (37 inches), making it easy for patients with medical conditions to access the chair from the front or the side with no obstructions, and allowing the operator to set the chair at a wide range of heights and tilts to achieve the perfect working position.
