An ergonomic mid back chair is a type of chair that is specifically designed to provide optimal comfort and support for the user, while having a mid-height backrest. These chairs typically have a backrest that sits around the mid-back area, which provides support for the mid-back. They may also include features such as adjustable lumbar support, adjustable armrests, and a tilt function. The chair is designed to promote good posture and reduce the risk of back pain and other injuries associated with prolonged sitting. Mid-back chairs are a good compromise between high-back and low-back chairs, providing both support and freedom of movement. They are also suitable for people of different body types and can match with different height of desks.
