The Sciszor has all the features of the Dynamic scissor system, with the added benefit that the weight adjustment feature is not longer needed, making it perfect for use in a range of users. Works to support your back by bringing the back support forward when you sit down. The angle of the support can be adjusted using the rear handle. For optimum positioning you need to place the support in the lower back to work with the natural S-shape of the back. The shape of the seat and the small back support work together to provide you with maximum support and freedom of movement.
