If you don't understand, it's recommended to read first and then buy. This blog will give you all the answers!!!

 

 

How does improper use of computer desks and chairs affect health?

 

When the human body is standing, the average pressure on the intervertebral disc is 100 psi, while the pressure on sitting is 150 psi, and when bending down, it is as high as 185 psi.

 

Most people don't sit in the right posture, leaning against the table, stooping and crossing their legs. These postures concentrate almost all the weight of the upper body on the lumbar spine in sections 4 and 5, resulting in uneven pressure on the intervertebral disc.

 

The resulting hazards include but are not limited to:

 

1. Long term compression of the lumbar spine in some positions will lead to a series of chronic diseases. Waist pain is the most common reaction.

 

2. Bending and hunching lead to reduced space in the chest and abdomen, affecting the function of respiratory and digestive system.

 

3. Working at the desk for a long time causes uneven stress on the cervical spine, compression and stretching of neck muscles, excessive local force of the body, resulting in muscle tension and pain, and shoulder and neck problems.

 

4. In the long run, the body will not be able to restore its natural posture. Poor sitting posture will continue to aggravate pain, affect health and posture.

 

How to choose a qualified computer desk?

 

The design principle of computer desk should conform to the principle of ergonomics. In short, the size of the computer desk should be coordinated with the user's height, chair height and body shape.

 

Size, disassembled is three elements: length, width and height. For the computer desk, the important levels of the three elements are:

 

High: decide whether the user can have a correct sitting posture.

 

Length: determine whether the arm can stretch and ensure the activity space. Good planning of property space brings better office experience.

 

Width: determine whether the desktop has enough space for arm support, which makes office more labor-saving.

 

Let's look at the selection requirements of 3 elements in turn

 

• Height selection criteria

 

In view of the limited environment and conditions, most people will still adopt the "three 90 ° sitting posture", that is, the knee bends naturally at 90 °; The thigh and trunk are 90 °, and do not bend over for a long time; The elbow is 90 °, naturally drooping without abduction.

 

• Length selection criteria

 

Your figure

 

The height of the table affects our lumbar spine and cervical spine, and the length of the table also affects the cervical spine. If the crowded desktop leads to insufficient space for hand activities, the shoulders will try to contract muscles, which will lead to pain for a long time.

 

Your planning of desktop space

 

The length of the desktop determines how large the screen, keyboard, mouse pad, etc. can be placed on your desktop. Taking the display as an example, the length of a small display is only half a meter. Some friends buy a large display with a length of 1.2 meters because of their career or hobby needs. They have high requirements for space, and it is only on the premise of a single screen.

 

• Width selection criteria

 

Generally speaking, the width of more than 70cm on the desktop will not appear narrow.

The distance from the forearm and palm to using the keyboard takes up about 45cm in width. If the thickness of the monitor and bracket is included, it will occupy an additional space of about 25cm.

 

If the width of the desktop is not enough, the arm support is not good, and it is easy to get tired after typing for a long time, so the selection requirement for the width of the desktop is that the whole arm can be placed flat on the desktop.

 

In addition, it is not recommended to have storage space under the desktop. Too narrow activity space will lead to the inability of feet to stretch and affect the whole sitting posture.

 

How to choose a good computer desk?

 

The electric lifting table has become more and more popular in the past two years. It began to rise in Silicon Valley. The lifting table has been applied abroad for at least 10 years. The employees of large domestic factories have begun to enjoy the benefits of office equipment upgrading, but it is estimated that it will take some time for the whole people to popularize it.

 

Although the electric lifting table is not a high-tech, in addition to the constant length, width and height screening, there are also some purchase precautions:

 

• Core lifting function

 

The lifting mode of the lifting table is divided into two types, electric and manual, of which manual is divided into manual fixation and one-time fixation.

 

Electrically control the desktop lifting through the motor. Just press the lifting key panel configured on the desktop.

 

Manual operation is very easy to understand. Both methods are primitive, laborious to operate, and there is no high memory function. Each time you adjust the height, you need to test whether it is appropriate. The experience is not recommended.

 

• Tabletop

 

A look at the environmental protection degree of desktop plate determines whether it is healthy or not.

 

On the product details page, whether there is a special introduction to the material of the desktop and the release of harmful substances should be put under the key attention of the bedroom. Some brands of lifting tables also support purchasing their own desktops, but it will be more troublesome. Users with high requirements in this regard can consult customer service.

 

Second, the workmanship determines the use experience and service life.

 

This mainly depends on the desktop spraying process and the quality of corner wrapping. One way is to look at the product introduction, and the other is to look at the buyer's comments. Generally, the workmanship is good, and the comments will be more real.

 

Third, look at the upgrade requirements. The desktop design can also meet the ergonomics.

 

The circular arc concave desktop is more convenient for users to completely put their forearms on the desktop, so that their arms are more relaxed when working, and they will not feel uncomfortable because of insufficient support like the ordinary square desktop after working for a long time.

 

• Accessories

 

The accessories of the lifting table mainly include: monitor bracket, host support, wire management pipe and roller.

 

Monitor bracket: the height of the monitor determines the experience of standing and working. The best state is full head up, and there is no need to lower your head, so as to relieve the pressure on the cervical spine.

 

Wire management: it is mainly used for arranging wires under the table. Friends who prefer to be neat suggest to consider it. Of course, there are other simple methods, but a special wire manager will be more beautiful.

 

Roller: the roller is used to facilitate movement. The table is still heavy. It will be very difficult to move if it is not installed. If there is a need to move the desk, it is recommended to buy it.
