Profile Design's F-35 Adjustable Armrest Kit provides excellent options for customization so you can find your perfect position. These versatile aluminum armrests can be rotated to provide additional lateral support. The plush, Lycra-covered 16mm-thick EVA foam pads simply attach to the armrests with adhesive-backed Velcro so no straps are required. The pads are antibacterial and feature contoured edges for increased long-term comfort.
