Extended Tray Office Chair

Currently, there is no standardized product directly named 'Extended Tray Office Chair,' but similar needs can be met by combining relevant functional features. The following provides specific solutions based on existing product information and the structural characteristics of office chairs:

1. Combined Solution of Extended Seat Depth and Custom Tray
Among existing products, the 'LiberNovo Omni' computer chair offers a version with an extended seat depth of 48cm, and its 'Deep Black' color scheme is suitable for office settings. If further extension of the tray is needed, customization services in the office chair accessory market can be considered: some merchants offer tray height adjustment functions, supporting a lifting range of 5-15cm, with materials including steel and engineering plastics, suitable for different environments such as workshops and supermarkets. Users can combine the chair body with an extended seat depth with a custom tray to achieve an overall extension of the seat surface and tray.

2. Adaptability of Ergonomic Design to Extended Needs
The core function of ergonomic office chairs is to distribute body pressure, and extended designs need to balance support. For example, the '9D Armrest Computer Chair' uses a gravity-sensing tray that automatically adjusts the tilt angle according to sitting posture. If users require longer leg support, models with a wider seat depth adjustment range (e.g., over 50cm) can be chosen, along with detachable footrests to extend the effective usable length through modular design.

3. Key Considerations for Material and Load-Bearing Capacity
Extended trays require a focus on assessing load-bearing capacity. Steel trays typically have a load-bearing capacity of over 150kg, suitable for larger users; engineering plastic trays are lighter but need confirmation of whether they have passed BIFMA standard certification (international office furniture quality testing). For high-frequency use scenarios such as gaming, it is recommended to choose a thickened steel tray and pair it with anti-slip silicone pads to enhance stability.

4. Scenario-Based Selection Recommendations

• Office Scenarios: Prioritize the combination of adjustable seat depth and a liftable tray, such as the extended version of the 'LiberNovo Omni' paired with a 5cm lifting tray, to meet the needs of 8-hour sitting.
• Industrial Scenarios: Choose a steel tray with an anti-static coating, suitable for workshop environments, and confirm whether it supports special needs such as forklift handling.
• Home Scenarios: Consider modular designs, such as detachable footrests and extended seat cushions, to balance space flexibility and comfort.

Purchase Tips: When customizing a tray, provide the interface dimensions of the original chair body (e.g., bolt spacing, tray thickness) to avoid installation incompatibility; extended designs may affect the chair's center of gravity, so it is recommended to choose a model with a five-star base diameter of ≥70cm to enhance stability.
