When your work requires that you sit for long periods of time, it is very important that you use an ergonomic chair. There are many types of desk chairs available but if it is not ergonomic it most likely will not address the problem of stress that’s caused to your spine from several hours of sitting. An ergonomic chair is designed to support the curve of your lower back, or lumbar, and promote good posture while you work. There are many factors that set an ergonomic chair apart from regular desk chairs. The material should be soft and breathable such as an ergonomic leather office chair. The seat height, width, and depth are important for lumbar support. The standard width is 17-20 inches, depth should allow 2 to 4 inches of space between the back of your knees and the seat, and height for most people is in the range of 16 to 21 inches from the floor. Backrest and armrest should also be adjustable to support the lower back and forearms properly. The foam padding in an ergonomic leather office chair offers firm and lasting support while remaining soft to the touch. Other desk chairs can feel springy or floppy in the armrests, which is unhelpful when you’re using them to get out of your seat. The durability of leather combined with the timeless usability of an ergonomically designed chair make the combination of the two a worthwhile investment.
