Office Chair Tray Size

Admin October 14, 2026

The size of an office chair tray mainly involves the long-side screw hole distance and the tray hole diameter, with common specifications for the tray hole diameter including 2.8 centimeters (gas rod socket), 25 - 30 millimeters, and 22 millimeters.

When measuring the size of an office chair tray, if the focus is on the long-side screw hole distance that connects to other components of the seat, simply measure this distance accurately. This dimension varies depending on the design and model of different office chairs, and precise measurement provides accurate data for subsequent replacement or maintenance.

Regarding the tray hole diameter, the diameter of the gas rod socket is usually fixed at 2.8 centimeters. The gas rod is a crucial component for enabling the height adjustment function of an office chair, and this standard size ensures a stable connection between the gas rod and the tray, guaranteeing smooth and safe height adjustment operations.

Another common range for the tray hole diameter of office chairs is 25 - 30 millimeters. This size specification is compatible with standard gas rods and ensures the stable operation of the height adjustment and rotation functions of the office chair. Within this size range, the tray and the gas rod fit closely together, preventing the gas rod from becoming loose due to an excessively large hole diameter, which could affect safety and stability, and also avoiding difficulties in gas rod installation or damage to components due to an excessively small hole diameter.

In addition, some office chairs adopt a tray hole diameter of 22mm. This relatively small hole diameter design may be based on the overall structure and usage requirements of specific office chairs. For example, some office chairs with a more compact and lightweight design can use a 22mm tray hole diameter to optimize the overall size and weight of the chair while meeting basic functional requirements, enhancing ease of use.

Understanding these key size information of office chair trays is of great reference value, whether for purchasing suitable accessories for repair and replacement or for customizing office chairs that meet specific needs. During the operation, be sure to use precise measuring tools to ensure the accuracy of the measured data and guarantee the normal use and safety of the office chair.
