The office workstation should let the worker sit and carry out their duties in comfort while allowing for voluntary changes in the working position.

There are three contact areas in the work space that affect the worker's posture: the seat, the work surface (commonly it is a desk top or keyboard) and the floor. To ensure the most comfortable posture possible, two of these factors have to be adjustable.

Adjust the seat to the comfort height.

Stand in front of the chair, push the lever, raise or lower the seat of the chair until its tip is under the knee. You should now be able to sit comfortably in a chair with with both feet flat on the ground.

Adjust office chair and evaluate the elbow angle.

Move the office chair as close to the desk as possible so that the upper arm drop slightly, parallel to the spine, and the hands can be easily placed on the table or keyboard. Adjusting the seat height up and down to ensure that the upper arm and the forearm are at right angle. At the same time, adjusting the height of the armrest allows the upper arm to just lift slightly.

Make sure your feet are placed at a right height

Put your feet flat on the floor and make sure a cross-finger width between the seat edge and the thigh. When sitting in the right position, the knee joint is about bent by about 90 degrees. If you are tall and have a large distance between your thighs and cushions, raise the seat, or if there is no space between the thighs and the cushions, lower the seat or use the foot rest.

Measure the distance from the calf to the edge of the seat

To sit back as much as possible, rest the waist to the back of the chair, the distance between the calf and the seat should be approximately approximately 5 cm. This distance determines the depth of the seat, and the correct depth prevents the waist from collapsing or falling out of the waist. If the calf is pressed on the seat, adjust the backrest forward, or use the waist back to reduce the depth. If the space between the calf and the seat is too large, adjust the backrest backward and increase the seat depth.

Adjust the seat back height

Adjust the backrest height so that it fits the radian of the waist and the waist back is supported to the maximum extent. When the backrest height is correct, you can feel the waist is firmly supported.

Adjust the backangle

To adjust the backrest angle so that it fits the waist.

The correct back angle supports your waist in the most comfortable position without having to lean forward or back. Do not shrink your body into a chair when you feel tired, which will add pressure on the back and lumbar disc . Keep your hips close to the back of the chair, it's better to put a cushion so that your back can bend slightly, so that when you're tired, your body won't shrink and it can reducing the pressure on your back to a minimum.

Adjust the height of the armrest

Adjust the height of the armrest to make sure that your elbow would not touch the armrest when it is 90 degrees.

If the elbow touches the armrest, the upper arm would be upward, which increase the pressure on the neck and shoulder prevent the arm from moving normally, increasing the burden on the wrist and fingers.

Adjust the height of your sight

Sit on the chair, close your eyes, face forward naturally, and open your eyes. When the computer screen is in the right position, we should be able to look directly into the center of the screen and see every corner of the screen without twisting or moving up and down. If the display position is too high or too low, then you need to make some adjustment reduce neck muscle strain. 

Smugdesk introduces modern technology and big data analytics into product design. Designed on the basis of bionics, the back of the ridge has a curve consistent with the human spine, in line with the natural curvature of the spine in which the body sits, and can be more closely aligned with the human body to help release spinal pressure.

Smugdesk continuously perfects the product research and development manufacturing system from the perspectives of creativity, technology, products, control and standards, and achieves the perfect user experience through a series of technological innovations such as the detailed research of big data, which provides a product foundation for the sustainable development of the Smugdesk.
