The option Removable Seat is an accessory for the medical training therapy device Butterfly/Press Back. This accessory is used for an alternative use of the device. In its original condition, the device is used in a seated position. With the Removable Seat option, the seat can be easily and quickly removed. This allows the trainee to use the device while standing or for a wheelchair user to train on the device. Please note that this option is not retrofittable. It cannot be installed at a later time. You can find many more training devices in our online shop. These training devices can be used both in medical training therapy and in fitness studios.
