Comfort design of ergonomic chairs
For office workers and game enthusiasts, sitting and working for a long time is really harmful to the body. However, the "standard" office chairs provided by most companies or ordinary writing chairs used at home cannot effectively provide much for correcting sitting posture. Good protection, so low back pain and cervical pain have become "occupational diseases" for many people. Compared with the occupational diseases caused by prolonged sitting, the cost of purchasing a comfortable ergonomic chair not only reduces physical pain, but also saves a lot of medical expenses, which is undoubtedly quite cost-effective.
Ergonomics mainly adjusts comfort from the following aspects:
1. Head:
The height and rotation of the headrest can be adjusted, allowing the user's cervical vertebra to naturally fit into the headrest, standardizing the user's sitting posture, and making office work a pleasure. The best position is when the height of the headrest fully supports your cervical spine. A good headrest can fit your neck perfectly, reduce the pressure on the cervical spine, effectively reduce the deformation of the cervical spine and prevent the occurrence of cervical spondylosis.
2. Chair back:
The best support position for the waist is the third and fourth vertebrae. The entire chair back is height-adjustable, which can easily and easily meet the needs of different users and reduce most of the human body weight borne by the lumbar vertebrae. Ordinary seats are extremely simple in design and cannot effectively fit the spine, causing parts of the spine to bear greater pressure. Hunchback has become the norm for most people who sit for long periods of time. Over time, it causes spinal deformation that is difficult to correct; and ergonomics The design of the back of the chair takes into account the pressure on the spine, and can effectively fit the spine, so that the stress on the spine can be even, and avoid hunching.
3. Lumbar support:
Separate movable lumbar support, the rebound force is concentrated on the movable lumbar support, giving the user the closest support. The movable lumbar support adjusts the curvature so that the entire lower back can relax and fit comfortably on the lower back, allowing the back spine to relax, thereby relieving the fatigue of the back spine. Some ergonomic chairs use a design that separates the waist and back. A separate lumbar pillow is designed, which can be automatically adjusted according to the user's waist shape. Whether sitting upright or leaning back, the waist can receive balanced and comfortable support and release waist pressure.
4. Armrest:
Adjust the height and angle of the armrests to create a smoother transition between your hands and the tabletop to prevent mouse hands. Free angle adjustment, stepless locking, arc-shaped back design, bow frame strength and elasticity treatment, armrest arc-shaped streamline treatment, etc. The armrests of general chairs are fixed and cannot be adjusted freely, and people's body shapes are not the same. Therefore, if you use the mouse and keyboard for a long time, you will feel the pressure from your shoulders, which may lead to frozen shoulder and mouse stick. , the gain outweighs the loss. The design of the ergonomic chair takes this into consideration, and the armrests are designed to be 3D freely adjustable, which can be adjusted freely according to one's own body shape, fully reducing the pressure on the shoulders. Some ergonomic chair armrests can be adjusted in 4D and have powerful functions.
