Old-Style Wooden Office Chair
Old-style wooden office chairs fall within the category of traditional wooden chairs, embodying the essence of traditional woodworking in their structure, materials, craftsmanship, and functional design. The specific characteristics are as follows:
1. Structural Craftsmanship: Mortise-and-Tenon Joints as the Core
Old-style wooden chairs are typically characterized by mortise-and-tenon joints, achieving a stable connection through precise interlocking of wooden parts. For example, a mortise is carved beneath the seat, and a tenon is crafted on the leg, which are then snugly fitted together without the need for nails or glue to ensure structural strength. Hardwood seats from the Ming and Qing dynasties emphasized the unity of form and structure, such as folding chairs that met portability needs while maintaining stability through the combination of mortise-and-tenon joints and movable axles. The Zhushan Guandu wooden chairs in Hubei, made from masson pine and assembled using mortise-and-tenon joints, were listed as an intangible cultural heritage of Shiyan City in 2016, reflecting the value of traditional craftsmanship inheritance.
2. Material Selection: Hardwoods as the Primary Choice, with Emphasis on Drying and Grain
Old-style wooden chairs mostly use well-dried hardwoods, such as jujube wood, elm wood, and oak wood. These woods have straight grains, high density, and are resistant to cracking and deformation. Areas with many knots are avoided to ensure structural strength. The Zhushan Guandu wooden chairs in Hubei use masson pine, a softwood, but compensate for material deficiencies through special drying treatments and mortise-and-tenon craftsmanship. Hardwood seats from the Ming and Qing dynasties often selected precious woods like rosewood and huanghuali, balancing durability and artistic appeal.
3. Production Process: Rigorous Procedures and Standardized Dimensions
Traditional wooden chair production involves processes such as material selection, cutting, planing, mortising, and assembly. Taking the seat as an example, the standard dimensions are one foot five inches long, one foot four inches wide, and one inch two thick; the legs are about two feet high with a one-and-a-half-inch square cross-section; the backrest posts are about two feet two inches high, with evenly spaced crossbars to enhance stability. During assembly, crossbars are added between the legs, and installation is done by tapping with a wooden block to protect the surface and avoid damaging the wood. Some intangible cultural heritage inheritors modify dimensions according to modern ergonomics, such as adjusting seat depth or backrest angle, while retaining traditional craftsmanship like mortise-and-tenon joints.
4. Functional Design: Ergonomic Fit, Balancing Practicality and Comfort
The backrests of old-style wooden chairs typically have a slight backward tilt to fit the human sitting posture and reduce fatigue from prolonged sitting; the crossbars between the legs not only enhance stability but also serve as footrests. Some styles, like the official's hat chair, achieve visual and functional unity through flowing curve designs. Modern improved versions may add cushioned seats or adjustable features, but the core structure remains based on mortise-and-tenon joints, reflecting the integration of traditional craftsmanship with modern needs.
