Mambo Max Standard Cushion, Junior and Senior air cushions are used for physiotherapy, balance and coordination exercises. They can also be used as an active and dynamic seat as it improves proper posture and exercises the back muscles. They have a smooth surface side and an uneven surface side. Easy to transport, and to clean, since their PVC surface is simply cleaned with soap and water. They differ only in diameter: the Junior is 33cm while the Senior is 37.5cm in diameter, both 7cm high and accompanied by small inflatable pumps.
