Metal Tray Office Chair

The metal tray office chair is a type of office chair that uses a metal tray as its core support component, with a variety of accessory prices and specific technical requirements for structural design and installation.

Accessory Prices and Types

The wholesale prices of accessories for metal tray office chairs vary significantly depending on material, function, and design. The basic iron spray-coated tray has a minimum wholesale price of ¥6.65, suitable for budget-friendly office chairs; the thickened explosion-proof square tray (with height adjustment handle) has a wholesale price of up to ¥19.0, emphasizing safety and functionality; the aluminum alloy P-shaped base (frog base) has the highest wholesale price of up to ¥58.9, mostly used in high-end ergonomic chairs. Other common types include:

• Die-cast aluminum alloy tray (¥40.0): Combines strength and lightweight design, suitable for swivel and lounge chairs;
• Middle-class base swivel chair tray (¥17.0): Designed for middle-class chairs, balancing load-bearing capacity and cost;
• 10X10 thickened swivel chair tray (¥4.75): Ultra-thin design, suitable for minimalist-style seats.
  Price differences mainly stem from combinations of material (iron/aluminum alloy), process (spray coating/die casting), and additional functions (height adjustment/explosion-proof).

Structural and Functional Characteristics

The core function of the metal tray is to connect the seat cushion, gas lift, and five-star base, enabling seat height adjustment, rotation, and load-bearing. The Deli 4905 office swivel chair uses a steel five-star base with a pneumatic height adjustment mechanism, requiring its metal tray to withstand dynamic loads and ensure stable insertion of the gas lift; the P600 computer chair features a more complex tray design, requiring precise alignment with the gas lift through holes and integrating a height adjustment handle. Premium models like the aluminum alloy P-shaped base also incorporate ergonomic curves, allowing angle adjustment of the tray to distribute hip pressure and enhance long-term sitting comfort.

Installation Technical Points

Tray installation is a critical step in assembling an office chair. Taking the P600 computer chair as an example:

1. Hole Alignment: The tray must perfectly match the pre-drilled holes on the bottom of the seat cushion to ensure the gas lift inserts without misalignment;
2. Height Adjustment Handle Fixation: The handle is secured to the side of the tray with screws, requiring a check for rotational flexibility;
3. Gas Lift Connection: Lubricating grease should be applied to the central hole of the tray and the top of the gas lift to reduce friction and noise;
4. Load-Bearing Test: After installation, simulate human weight (recommended ≥100kg) by pressing down to verify no deformation or abnormal noise occurs in the tray.

Metal tray office chairs balance cost and performance through modular design, allowing users to choose between iron or aluminum alloy trays based on budget and prioritize safety parameters such as explosion-proof and load-bearing capabilities.
