Structures of an ergonomic chair.
Answers
Answer:
Ergonomic chair features
1. Seat height
The optimal seat height should allow you to place your feet flat on the floor, which is why choosing a chair with an adjustable seat height is essential because everyone is different. What’s more, with most work desks remaining at a fixed height, it is important that the seat height can be altered. A seat height that ranges from 16 to 21 inches off the floor should work for most people.
2. Seat width and depth
Proper seat depth should leave between 2 and 4 inches between the edge of the seat and the back of your knees. If the seat is too far forward, it may put undue pressure on the back of the knees.
3. Seat tilt
Good ergonomic chairs will allow the seat to tilt, which allows for correct positioning of the pelvis. The anterior pelvic tilt is a posture problem that affects almost everyone who sits a lot, which is why it’s important to keep the pelvis in a neutral position when sitting, with 80-degree angles at the hips, knees, and ankles.
4. Backrest Lumbar support
This refers to the support given to your lower back and is an essential feature of an ergonomic chair. Ergonomic chairs support the natural ‘S’ shape of the spine, which prevents slumping and reduces stress on the spine and the pelvis. An adjustable backrest allows users to align the curve in the chair with the curve in their spine, for optimal support.
5. Backrest recline
An adjustable backrest allows for greater tailored positioning for the user, as they can move the backrest to more specifically support their natural spine position. Using this feature throughout the day allows the backrest to take some of the weight from your upper body, reducing the pressure on your spinal disks and muscles.
6. Swivel
The swivel in an ergonomic chair helps users with their maneuverability, making it easier to reach different points of their desks without having to strain excessively.
7. Armrests
Armrests help to reduce tension in the upper body and allow the shoulders to relax. However, armrests should not be used when typing as this reduces overall arm movement, which in turn increases wrist movement leading to strain on the forearm muscles.
8. Headrest
Supports the back of the head and the upper neck, reducing tension in the shoulders and upper torso.
9. Materials
A good ergonomic chair is made out of comfortable materials. The material should not cause the user’s back to sweat. However, the materials used will depend on the budget; high-end ergonomic chairs will use leather or velvet.
10. Wheels
If your chair will be used on a hard surface, find a chair with soft rubber wheels. If your workplace/home office is carpeted, opt for hard wheels to help you navigate better.
