Standard size of a writing desk - What is the price of a writing desk?
The price of a writing desk is very different depending on the brand of different materials. Currently, the materials for writing desks are generally triplex panels, solid wood, stainless steel, etc. The price ranges from a few hundred yuan to tens of thousands of yuan.
Most of the writing tables are made of medium-density fiberboard, a few are made of particleboard, and some are made of steel and wood structures and solid wood with semi-medium-density plate and semi-steel pipes.
According to the surface materials of the board, there are mainly two types: PVC vacuum blister and melamine. PVC vacuum blister is beautiful, environmentally friendly, water-resistant and comfortable. The manufacturer has a large investment in equipment, representing manufacturers including Qianlima, Zhanjiang, Guangdong and Shanghai Xiangshang. The surface hardness of melamine is slightly high, high temperature resistant and simple to make, and can be made by self-employed people who engage in home decoration.
The width of the desktop is mostly 70 cm, 75 cm, and 80 cm.
Purchase a writing desk and pay attention to whether there is a formaldehyde emission test report and whether there is a real furniture certificate. Some manufacturers and sellers call melamine cover panels fireproof boards (refractory boards), which is a deceptive behavior. To verify the fireproof board, you need to look at the cross section where the PVC edge is removed. The thickness of the true fireproof boards should be above 0.6 mm (about the thickness of a hacksaw blade). No fireproof board writing tables have been found. The standard size of the writing desk is too high and the chair is too low, which will cause people to lie down and shorten the visual distance. Over time, it will easily cause spinal bending and deformed deformation and myopia of the eyes. To this end, the furniture used daily must meet the standards; the national standards have stipulated the height of tables and chairs. Among them, the height dimensions of table furniture can be 700mm, 720mm, 740mm and 760mm.
The seat height of chair and stool furniture can be 400mm, 420mm and 440mm. In addition, it is also stipulated that the standard size of tables and chairs should be used, and the height difference between tables and chairs should be controlled within the range of 280 to 320mm; the correct height of tables and chairs should enable people to keep two basic perpendicular when sitting: First, when the legs are placed flat on the ground, the thighs and calves can be basically perpendicular. At this time, the front edge of the seat cannot impose a pressure on the lower thigh plane. Second, when the arms are naturally drooping, the upper arm and the forearm are basically perpendicular. At this time, the height of the tabletop should be in contact with the plane below the forearm. This will enable people to maintain the correct sitting posture and writing posture
If the height of the table and chair is unreasonable, it will directly affect the sitting posture and be detrimental to the health of the user. To this end, the national standard also stipulates that the height of the space under the desk table is not less than 580mm and the width of the space is not less than 520mm. This is to ensure that people have enough space for their legs to move when using it.
