Backrest of the Ergonomic chair:

            If the backrest of the Ergonomic Chair is not designed properly with inadequate size, material, and positioning, the back support will not be sufficient. This would lead to inappropriate postures that cause back pain and fatigue. A Ergonomic chair without suitable or appropriate backrest will fail in supporting your lumbar spine and won’t maintain the natural S-shape curvature of the spine.

• Roll up a towel at the lumbar region or place a removable back support cushion for a temporary support if the Ergonomic Chair that you use currently doesn’t provide a good lumbar support. This would help you maintain the natural curve of the spine.
• You can try using a Ergonomic Chair with easily adjustable backrest and which supports the back in all your convenient seating postures (Ergonomic Seating). A backrest should have the following features:
• The backrest should have a good lumbar support with adjustable height options for fitting the lower back in different postures. Ensure that the outward curve of the backrest should fit into the small of the back.
• The backrest should have an adjustment that allows the user to recline at least 15 degrees from the vertical. The backrest should lock in place or be tension adjustable so that adequate resistance is ensured to the lower back movement.
• Shorter users can sit with their backs against the backrest without worrying about their knees touching the front edge of the seat pan with the help of a device that enables to move forward and backward. Taller users can sit with their backs against the backrest while supporting their thighs and buttocks fully.
