Chair types are commonly referred to as armchairs or standard chairs, depending on their structural design. Most chairs are manufactured using a knock-down (KD) construction method unless otherwise specified. While the basic structure of an armchair and a standard chair is similar, an armchair typically features additional armrests, making it more complex in design.
Chairs are generally assembled using components such as the seat back, seat cushion, front feet, and frame armrests, connected with screws, dowels, and tongue-and-groove joints. This modular approach allows for easy transportation and assembly.
Front Foot
1. The front foot is positioned at the front end of the chair and serves as a critical support point, connecting the seat frame and bearing the weight of the entire chair.
2. Front feet are typically made from solid wood and are usually crafted in two parts: the front foot itself and the connection point to the seat frame. There are two common methods of attachment: one where the left and right front feet are installed separately into the seat frame, and another where both sides are joined as a single unit before being attached.
3. The shape of the front foot can vary based on design requirements—common styles include curved edges, carved details, grooves, and rounded corners. In most designs, the following key points are considered: a) the lower edge of the front foot should align with the angle of the rear foot to ensure stability; b) the joint between the front foot and the seat frame should be at a 90-degree angle or slightly more; c) part of the corner may be cut off to allow for the insertion of two internal and external teeth in KD structures, which lock the joint at 90 degrees.

4. When drilling holes in the upper part of the front foot, the inner and outer hole positions must align with the screw holes on the frame. A pilot bit should be used to prevent the wood from splintering when tapping the holes.
5. The material used for the front foot must be strong enough to withstand the pressure from a person's legs. It should pass strength tests to ensure long-term durability.
6. To prevent damage during movement, the lower end of the front foot is often designed with an inward curve (R3 or R5), reducing the risk of the edge breaking off when the chair is pushed or pulled.
7. All exposed surfaces of the front foot, including carved edges and corners, should be smooth and free of sharp points to avoid causing injury to users.
Whether you're designing a chair for mass production or custom furniture, understanding the role of each component—especially the front foot—is essential for ensuring both functionality and aesthetics. Proper attention to detail in the front foot design not only enhances the chair’s stability but also contributes to a more comfortable and visually appealing product.
