ONGO®Roll – all around more mobile

The ONGO®Roll should really be called “Rock ’n’ Roll”. Due to its flexible seat placement this ergonomic designer stool doesn’t just roll, but also rocks. This ONGO® also creates the kind of dynamic sitting that promotes health. At the same time, it provides the greatest possible range of movement.

Our innovation is the flexible seat placement, which responds to your body’s requirements not only by tipping or leaning, but also by moving horizontally. The range of movement can be set on the adjustment ring below the seat. The force needed for the movement adjusts itself to the weight of the user.

The ONGO®Roll comes in two height ranges, regular (52–63 cm, 20.5–24.8 in.) and tall (59–77 cm, 14.6 – 11.8 in.). A hydraulic spring makes for easy height adjustment. This makes the Roll ideal for a variety of roles: in the office, factory, hospital or at home. Both heights are available in black or white. The ergonomically curved seat comes in 40 varieties of upholstery. The ONGO®Roll is also available with a saddle seat, optional with a cushion in three colors.

The ONGO® design and high-quality craftsmanship satisfy the highest demands of long-lasting service and enjoyment. Contributing to environmentally sound solutions, the ONGO®Roll, like all ONGO® Active Sitting products, is manufactured in Germany.
