Aggregated specification data for the Uncaged Ergonomics Wobble Stool lists a Class-4 gas piston for height adjustments between 23 and 33 inches. The 13-inch diameter base is weighted with a counter-balance to ensure a self-righting center of gravity. The physical architecture is designed for perching, with movement governed by the curvature radius of the weighted base.
Structural dimensions confirm the use of high-density foam for the seating surface. Technical teardowns indicate that the stool is stationary, lacking a caster module, which stabilizes the unit during tilt maneuvers. Proper maintenance involves ensuring use on a level surface to prevent lateral strain on the pneumatic cylinder seals, which could lead to pressure loss over time.
Functional features include a tool-less friction-fit assembly. Performance metrics indicate the foam may reach high compression points during continuous use exceeding 4 hours. The mesh fabric cover is a standard synthetic weave; users are advised to monitor for surface pilling when used with abrasive materials like denim. The Class-4 rating provides a higher durability threshold for frequent height modulation compared to Class-3 units.
The Adjustable Wobble Stool for Active Seating by Uncaged Ergonomics features a Class-4 gas piston, making it a more durable alternative to stools using lower-rated cylinders.
This device is cataloged under standing desk stools within the ergonomic peripherals database.
