Office Chair Stability Tester. Office Chair Forward Stability Testing Machine. Seat Stability Test Equipment. Furniture Chair Stability Testing Machine. Office Chair Stability Test.

The Office Chair Stability Testing Machine is designed to evaluate the forward stability of office chairs and similar seating products. By applying a specified cumulative load on the seat while adding a 20 N pull force in front of the load point, the machine checks whether the chair tips forward, thus determining its compliance with international standards.

* Tests the forward stability of office chairs, seats, and similar furniture.

* Simulates real-world tipping conditions with seat load and pull force.

* Provides reliable data for product safety evaluation and certification.

* Widely used by furniture manufacturers, testing laboratories, and quality inspection centers.

* Rigid test platform with spacers to block the chair's front legs.

* Loading pad (Dia.200mm , R300mm) positioned 60 mm from seat front edge.

* Loading rod with interchangeable ends: spherical SR19 mm (Type A) or 45° tip (Type B).

* Manual weight basket lifting system for accurate cumulative loading.

* Optional pneumatic interface for stable auxiliary air source (6 kgf/cm²).

* Compact and durable frame for accurate forward tipping stability tests.

Complies with or references the following standards: EN 581-1 / EN 581-2 / EN 581-3, EN 1022, EN 1729-2, and ANSI/BIFMA X5.1.

Unlike trading companies or OEM resellers, we are a vertically integrated manufacturer - owning our R&D, production, and quality control under one roof.
Every Huakai product is designed, engineered, and manufactured entirely in-house, giving us full control over precision, lead times, and customization depth that most suppliers simply cannot match.
Self-Developed, Not Sourced Our in-house engineering team holds multiple patents. We develop our own control systems, thermal management modules, and test software - not dependent on third-party core components that limit flexibility.
Fast Delivery Without Compromising Accuracy Standard models ship in as little as 7--15 business days. Our streamlined manufacturing process - not shortcuts - makes this possible.
Customization That Actually Goes Deep When clients require non-standard chamber sizes, unique temperature profiles, or integration with their existing data acquisition systems, we engineer a real solution - not just a relabeled catalogue product.
Global Compliance Built In All products are CE certified and comply with IEC, ASTM, MIL-STD, and GB standards. Our chambers have helped clients pass certifications across consumer electronics, EV batteries, automotive components, aerospace, and medical devices.
