I. Dimensions of mahogany furniture chairs
1, sitting depth-sitting depth refers to the distance from the front edge to the rear edge of the chair, which has a great influence on the comfort of human sitting.
2. Height of backrest-The size of backrest is mainly related to the height from the bottom of hip to shoulder (which determines the height of backrest) and shoulder width (which determines the width of backrest). The height and width of the chair backrest, the maximum height of the backrest can reach 480mm~630mm, and the maximum width can reach 350 mm ~ 480 mm
3. Sitting height-sitting height refers to the vertical distance from the seat surface to the ground. Because the chair surface often leans backward, the sitting height of mahogany chair is usually the height of the front sitting surface as the sitting height of mahogany chair; If the sitting surface is backward or concave arc, the sitting height refers to the vertical distance from the center of the sitting surface to the ground.
4, sitting width-the width of the mahogany chair sitting surface is often wide in front and narrow in back according to people's sitting posture and movements. The width of the front edge of the sitting surface is called the width before sitting, and the width of the rear edge is called the width after sitting.
5. The sitting surface is tilted-when people are at rest, the sitting posture is that the body leans backwards, so that the lumbar spine is stressed. Therefore, most of the general seating surfaces are designed to tilt backwards, and the inclination of the seating surface is often 3~5 degrees, and the opposite chair back is also tilted backwards, and the lower one protrudes forward.
Second, the causes and maintenance skills of cracks in mahogany furniture chairs
1, cracking reason
Drying is the main reason for the cracking of mahogany furniture. In addition, we should pay attention to avoid direct sunlight. Air-drying combined with long-term sun exposure is easy to cause wood moisture evaporation and cracks. Try not to open the window too wide in winter except to avoid light. In dry winter, especially after heating, consumers should increase indoor relative humidity through different methods, such as using humidifier or regularly opening windows for ventilation and placing green plants. However, it should be noted that mahogany should not only be "dry-proof" but also "moisture-proof", so we must keep a balance between "dry" and "wet". The ideal moisture content of mahogany furniture should be about 12%.
2, maintenance skills
There is a big difference between north and south in winter and spring, and moderate oiling and waxing is also one of the ways to keep mahogany bright. Because the air in the north is dry, it is recommended to pay attention to refueling (to control the water balance through oil); Waxing is relatively used in the south (waxing to seal water and maintain water balance).
In addition, the maintenance of furniture should also conform to the nature of wood. If the furniture is used for many years, it will gradually lose its luster and affect its appearance. In this case, you can bake the beeswax in the sun or by the fire and rub the old leather shoes brush repeatedly, so that the brush is covered with many tiny melted wax particles. Then brush the furniture repeatedly with this brush covered with wax particles. This method is called "dry wax shaking". After the "dry-shaking wax" treatment, the furniture that lost its luster immediately "glows".
