Structural analysis of the SONGMICS Wobble Stool (B07VF45PPL) identifies a Class-3 pneumatic gas lift that provides 25cm of vertical travel. The base is a high-density PVC/PP composite weighted with internal ballast to establish a self-righting center of gravity. This configuration supports an 8-degree tilt radius while preventing tip-over during use.
Material and Compliance Data
The seating surface uses 2.4 inches of high-density fire-retardant foam covered by 280g/m² polyester fabric. Material analysis confirms the gas cylinder is SGS-certified for loads up to 120kg (265 lbs). Technical datasheets indicate that while the base is non-slip, aggressive usage on hardwood may produce micro-scuffing, necessitating a protective surface interface.
- Rotational spec: 360-degree low-friction swivel.
- Height range: Approximately 9.8 inches of travel.
- Form factor: Armless, backless perching design.
Operational data suggests that high-density foam may feel rigid during sessions exceeding 4 hours. The absence of a lumbar support module requires the user to maintain spinal alignment via core engagement. The tool-less assembly design facilitates rapid workstation integration.
Users seeking a higher-spec 280g/m² polyester fabric may consider the SONGMICS Adjustable Ergonomic Wobble Stool, Ink Black as an alternative to standard mesh variants.
This hardware is an active seating solution within the standing desk stools classification.
