Technical documentation for the SONGMICS Wobble Stool specifies a Class-3 gas lift that provides 22cm of vertical travel. The base architecture consists of a weighted PVC chassis with a 33cm diameter, engineered to provide a return-to-center force. This physical dampening mechanism allows for 360-degree tilt maneuvers during operation.
Material science reports indicate the use of 2.5-inch high-density foam for the seating surface. Structural analysis highlights that lateral torque applied to the cushion-to-shaft interface is a primary stress point for the swivel bearing. Proper operation requires a low-pile or hard surface to maintain the intended friction coefficient of the PVC grip and prevent premature wear of the tilt radius.
Operational data suggests that system fatigue may increase during sessions exceeding 4 hours due to the absence of a lumbar support module. The maximum load rating is established at 265 lbs; exceeding this threshold may result in uncommanded gas lift sinkage. Functional highlights include a 3-stage modular integration process requiring no external tools.
Users requiring a specific 2.5-inch foam density may find the SONGMICS Adjustable Ergonomic Wobble Stool a superior alternative to generic active seating units.
This device is an example of high-mobility hardware within the standing desk stools category designed for intermittent task-switching.
