Material stress reports for the Iwmh Wobble Stool indicate a frame composed of glass-fiber reinforced polyamide, providing high tensile strength for the chassis. The pneumatic system uses a Class 3 or 4 gas cylinder, delivering a height adjustment range between 55cm and 75cm. A convex base plate, weighted with thermoplastic rubber (TPR), facilitates a tilt range of 15 to 28 degrees.
Structural dimensions include a 60kg/m³ high-density foam seat, which provides significant resistance to deformation but may result in high surface pressure during extended use. The polyester mesh cover provides the primary tactile interface. Maintenance protocols suggest the annual application of lithium-based grease to the gas lift actuator pin to ensure smooth 360-degree rotation and prevent mechanical creaking.
The lack of casters in this architecture ensures the pivot point remains stationary, though it limits horizontal mobility across the workstation floor.
Functional metrics confirm a maximum weight capacity of 120kg (265lbs). The friction-fit design enables assembly in approximately 120 seconds. Limitations include potential pilling of the mesh fabric when in contact with abrasive textiles and a stiff seat pan profile that may affect user comfort during long-duration deployments.
The Adjustable Ergonomic Wobble Stool for Home Use offers a distinct high-tensile polyamide frame compared to standard plastic alternatives.
This unit is cataloged under standing desk stools as a mechanical peripheral for core-engagement seating.
