This chair has a number of features that contribute to its ergonomic design. For starters, it has an adjustable backrest that can be tilted to support the natural curve of my lower back. This has been a game changer for me, as I used to experience discomfort and pain in my lower back after sitting for long periods of time. The chair also has adjustable armrests, which allow me to rest my arms at a comfortable angle and take pressure off my shoulders.
