Furniture is an indispensable necessities in people's lives and work. Mastering some relevant knowledge is very necessary for consumers to purchase furniture that is satisfactory and worth the money.
Wooden furniture structure
Traditional solid wood furniture is a fixed structure, and the current furniture has a disassembled structure and a semi-detachable structure.
The fixed structural components are matched with each other by blinking, and are glued relatively firmly. This kind of structure is not only difficult to construct, but also difficult to mass-produce, and because of its large size, it is inconvenient to move and change the room layout or migration, and it is easy to bump and scratch.
The disassembled structure and the semi-detachable structural component are integrally formed by the connecting piece. Due to the high processing requirements, its precision is more rigorous than the fixed type, it can be disassembled and it is very convenient to install.
In terms of paint finishing, the disassembled or semi-detachable type is superior to the fixed type.
The essentials to master before purchasing
To purchase wooden furniture, first measure the area of ​​the furniture in the room, and calculate the specifications such as length, height, width, and depth. When purchasing, be sure to check in. When the new furniture is equipped indoors, the area occupied by the furniture should be taken into account. The plane area should not exceed 45% of the floor area, and the highest wall furniture should not exceed 80% of the wall height.
To purchase furniture placed in the same room, pay attention to the unity of style, style and style, and the color should be harmonious. If you are replacing individual furniture, you should also choose the same color as the original furniture in the room. Small rooms or rooms with poor lighting conditions should use light-colored or light-coloured color-blocking furniture to create a wider, brighter feel. Large rooms and light-filled rooms may choose dark furniture to accentuate the simplicity and elegance.
For the elderly to choose the furniture to grasp the height, it is best not to choose tall cabinets or joint cabinets and the like. Although such furniture can save space and is highly utilized, it is inconvenient and unsafe to ascend. Newly-married couples should purchase furniture in a forward-looking manner. They should consider the problem of the child after birth, and try not to choose the lower furniture of the glass door to prevent unsafe hidden dangers. Children's furniture should avoid sharp edges and corners, so it is better to choose a corner with a circular arc.
As for the style of wooden furniture, of course, it is the first choice that suits your personality and aesthetic taste. The more popular, the easier it is to “small-time†obsolete. However, the traditional style that has been tested for a long time is more infectious and enduring because of its heavy accumulation of cultural heritage beyond time and space.
Several items must be mastered before purchasing furniture. For example, the top surface of the bedside table should be higher than the bed drawer (excluding Simmons mattress) with a water level of 200 to 220 mm.
The depth of the hanging wardrobe should not be less than 500 mm, the height of the hanging garment in the cabinet should not be less than 1350 mm, and the space height of the hanging short garment should not be less than 850 mm. The vertical distance between the table top and the chair seat should be 280 to 320 mm. Since there are many differences between the height of the human body and the upper and lower body, it is best to choose the right one in this data range when purchasing or sitting on a chair at the desk.
Choose quality when buying furniture
Pay attention to quality when purchasing furniture. The material and the internal quality of the furniture depend on whether the wood material has any defects, shackles or worms; whether the joints between the parts have collapses or fine cracks caused by rough processing; whether the internal materials are processed Smooth and burr-free; whether the joint of the splicing joint or the joint is firm or not loose; whether the surface of the panel is flat without obvious warpage; the selected artificial board can not have the pungent smell of formaldehyde, and must be edge-sealed. Sticking wood or other decorative materials should be solid and smooth, and must not have defects such as opening glue, dents, bubbling; etc.; medium-density slats or chipboard strips should not be used as frame, column, struts and other load-bearing parts; Plastic slides, without slides, pull the drawer out 2/3, its sag should be within 20 mm, and the swing should be within 15 mm.
In the choice of appearance quality, it should be viewed from the whole: the symmetrical parts (especially the door of the bedroom frame) have the same or similar texture direction of the wood or other covering materials; whether the surface paint film is hard and full, smooth and smooth, no scratches and scratches. The color is uniform and the hand feels smooth and smooth. Some furniture, such as hanging wardrobes and glass decorative cabinets, should be treated with paint or other decorative materials and very clean. For mercury mirrors, the mirror must be equipped with a back panel and fixed with a bead.
