Mo-Ball Stability Ball Chair Set

Easily roll these chairs where they are needed to engage students' cores while learning. Both chairs include a strong powder-coated, 1" dia steel tubing base with a built-in support that cradles the ball while students sit on it. The backless design of Mo-Ball Plus promotes proper posture, while a contoured backrest on Mo-Ball Pro enhances support for longer periods of time. Chairs move smoothly on 4 inline 2-1/2" dia casters.

Set includes 3 Mo-Ball Plus (23"L x 23"W x 21"H with ball; 13 lb) and 3 Mo-Ball Pro Chairs (23"L x 23"W x 30-1/2"H with backrest; 15 lb). Each chair includes a 45 cm burst-resistant stability ball and supports up to 350 lb.
