Active sitting stool

The Wobble Stool Air is an ergonomic rolling stool designed for adults and students who want to stay active while seated. It replaces a static chair with a balance disc seat that encourages swaying, twisting and subtle movement throughout the day. The stool suits standing-desk users and classroom environments where flexible, engaging seating is preferred.

Thermals noise and power

This product has no electrical components, fans or power draw, so it generates no heat and operates in complete silence. The only sound comes from the casters rolling across the floor, which is minimal on typical hard surfaces. No batteries or mains connection are required for normal use.

Build fit and freedom

Height adjusts from 19 to 25.5 inches and the seat swivels 360 degrees, letting the stool tuck under most desks and move freely around a workspace. Assembly requires no tools, so it is ready to use straight from the box. The compact footprint saves floor space compared with a full-size exercise ball, while the wheeled base provides mobility without a fixed gas-lift cylinder.

Questions about this item

How do I assemble the Wobble Stool Air without tools?

The stool requires no tools for assembly; simply attach the seat to the base, insert the gas-lift cylinder, and secure the five-star wheel base by pressing the components together until they lock.

What part of the Wobble Stool Air will wear out first and need replacement?

The gas-lift cylinder that provides the 19 to 25.5 inch height range and the wobble cushion that creates the balancing motion are the components most likely to require replacement after extended daily use.

At what height does the Wobble Stool Air become unstable during sustained use?

The stool reaches its least stable point at the maximum 25.5 inch extension, where the higher centre of gravity amplifies the wobble motion and reduces the base’s effective footprint.
