A stationary bench seat with a backrest mounts securely to the floor, to provide added stability and satisfy ADA regulations for safety in changing or dressing rooms, locker rooms, saunas, and holding cells. It is constructed from #304 stainless steel frame and durable, water-resistant solid phenolic material, making it ideal for use in wet or dry locations, and supports loads in excess of 1,200 lbs. when properly installed. The seat features a removable backrest and has standard cutout slots to encourage drainage.
