Staff and Office Chair Tray

The staff/office chair tray is a core component of the seat that integrates functions such as height adjustment and rotation. The installation method, function type, and selection should be determined based on the specific model and usage requirements.

Installation Methods

The installation methods for trays vary depending on the model and should be carried out strictly in accordance with the product instructions:

• P600 Computer Chair Tray: When installing, use the shorter end as the rear end and secure it to the seat cushion with four short screws (specification: 6×20), ensuring that the height adjustment handle is located on the right-hand side when seated.
• Deli 4901S Staff Chair Tray: Secure it with four screws equipped with washers (specification: M6×30mm). The washers enhance stability and reduce wear.
  Before installation, ensure that the screw specifications match the hole positions to avoid installation failure or structural looseness due to size mismatches.

Functions and Types

The functional design of the tray directly affects the comfort and practicality of the seat:

• Basic Functions: Most trays integrate height adjustment and rotation functions, allowing for seat height adjustment (usually within the range of 40-50cm) and 360° rotation to meet daily office needs.
• Advanced Functions: Some high-end models support forward and backward rocking (such as heavy-duty export swivel chair trays) or are equipped with reclining mechanisms and lumbar support, suitable for long hours of office work or scenarios requiring flexible adjustment of sitting posture.
• Material Differences: Prices range from 9.22 yuan (basic plastic tray) to 528 yuan (high-end ergonomic metal tray). Materials include plastic, steel, aluminum alloy, etc., directly affecting load-bearing capacity and durability.

Selection Advice

When selecting a tray, consider both functional requirements and compatibility:

• Functional Matching: Choose functions based on the usage scenario. For example, if a reclining function is needed, select a tray with a reclining mechanism. If lumbar support is required, confirm whether the tray has reserved installation positions.
• Size Compatibility: The installation hole positions of the tray must match those of the chair body to avoid installation failure or structural instability due to size mismatches. It is recommended to measure the screw hole spacing at the bottom of the chair body and compare it with the tray parameters before purchasing.
• Accessory Services: Some merchants offer services such as a 7-day exchange policy and 24/48-hour shipping. Confirm the after-sales policy before purchasing to reduce risks.

For further information on the parameters or installation details of specific models, it is recommended to refer to the product's official instructions or contact the seller for confirmation to avoid damage due to improper operation.
