1、 Scope of application

Applicable products: chairs with tilting or reclining mechanical properties (such as office chairs, leisure chairs) and rocking chairs.

Test objective: To evaluate the chair's ability to fully recline（ZUIStability at large tilt angles to prevent tipping or structural failure.

2、 Core testing items and parameters

Loading disk specification: diameter: 350mm，Thickness 48mm

Quality: Configure according to chair type and testing requirements (e.g. 10kg/piece, quantity adjustable).

One supporting device weighing 2.3kg, with two elastic soft ropes

Test conditions:

Adjust the chair toZUILarge tilt angle (ifZUISmall tilt angle ≤ 55 °, testing should be conducted in a tilted state; If the angle is greater than 55 °, testing can be exempted.

Load the disc evenly distributed on the backrest or seat surface to simulate the actual force during use.

Result judgment: The chair should not have tipping, structural fracture, or mechanical component failure.

‌fiveExample of Operation Process

Rocking chair stability test

Test scope: Dynamic testing is conducted within the effective swing angle (usually 90 ° -120 °) to simulate forward and backward swing scenarios.

Loading requirement: The number of loading disks should be similar to that of a tilted chair to ensure dynamic stability assessment.

Result judgment: The rocking chair should not accidentally overturn or structurally damage during the swinging process.

Additional testing for reclining chairs

Chair with footstool: The stability of the footstool should be tested when folded or extended, and the loading method should be consistent with that of the main chair.

Chair without footstool: evaluationZUIThe impact of small tilt angles on stability ensures safety during low angle use.
