The backrest tilt angle can be of crucial importance: a forward leaning position can facilitate toileting performance. For showering, a backward leaning position may be needed. Whether the Blue Wave system is being used as a mobile shower or commode chair, or on the toilet, the backrest tilt can be adjusted.
Pulling the backrest adjustment triggers, as shown, quickly adjusts the backrest either 5° or 15° backwards, or 5° forwards (from the vertical). It is important to note that the seat itself is designed to slope 5° backwards. The backrest-to-seat angles that can be created are therefore: 80°, 90°, and 100°.
