Reserved Holes in Office Chairs

The functions of reserved holes in office chairs vary depending on their specific locations and designs, mainly including fixing tables and chairs, installing casters, facilitating handling, and providing ventilation and moisture resistance.

In scenarios such as the conversation areas in duty rooms, fixed holes are reserved at the bottom of the seats and tables of upholstered furniture. These holes usually employ metal embedded parts or reinforced steel plates with a diameter of 8 - 10mm. During installation, M8 or M10 expansion bolts can be used to directly lock the tables and chairs to the ground. This design can effectively prevent the displacement of tables and chairs caused by vigorous movements or external forces, thereby ensuring space order and personnel safety. For example, in the conversation areas of duty rooms where quietness and order need to be maintained, this fixing method can ensure that the tables and chairs do not slide randomly during use, avoiding noise or safety hazards caused by their displacement.

For office chairs that require the installation of casters, holes are reserved at the bottom of the chair legs. The caster screws of most home office chairs are of a unified M8 specification, and the inner diameter of the holes is about 8mm. During installation, first align the screw rod of the caster with the reserved hole at the bottom of the chair leg and slowly rotate it in the direction of the hole's thread. If the hole does not have built-in threads, use the matching self-tapping screws to create threads first and then install the casters. This design allows the office chair to move flexibly, facilitating users to switch between different positions and improving work efficiency.

In addition, the holes on the seats of some chairs (commonly known as 'finger holes' or 'ventilation holes' in the industry) also play an important role. These holes are commonly found on plastic chairs, dining chairs, and office chairs. In situations where a large number of chairs need to be stacked and stored, fingers can be inserted into these holes for easy handling. For plastic chairs, these holes can also provide ventilation and moisture resistance, preventing the seat surface from getting moldy. At the same time, during the injection molding process, these holes allow the plastic parts to cool evenly, preventing shrinkage and deformation, reducing material usage, and lowering production and transportation costs.
