Office Chair with Movable Backrest
The following two office chairs with movable backrests are available for reference:
Ergonomic Office Chair E500: The backrest of this office chair is movable and is designed strictly in accordance with ergonomic curves. Ergonomic curves are designed based on the physiological curvature of the spine in a natural sitting posture, enabling the chair to better fit the human body. When a user sits on it, the backrest can closely fit the back, providing uniform and comfortable support. This sense of fit helps to disperse body pressure, reduce fatigue caused by prolonged sitting, and allow the user to maintain a natural and relaxed state during office work, thereby improving work and study efficiency. Moreover, due to its ergonomic design, it can also, to a certain extent, prevent spinal problems caused by poor sitting postures, such as scoliosis and lumbar disc herniation, which is of positive significance for the user's physical health.
Herman Miller Sayl Classic Black Ergonomic Chair: The backrest of this chair has more abundant functions. It supports a forward-tilt function, which can meet the user's needs in different work scenarios. For example, when the user needs to focus on fine tasks such as writing and drawing, the forward-tilted backrest can provide closer support, allowing the user to maintain a forward-tilted posture without feeling strenuous. It adopts an integrated single-back design, providing a sense of integrated wrapping for the waist and back when leaning on it. This sense of wrapping can enhance the stability of the waist and back, reduce waist movement, and provide better protection for the waist. The backrest material is soft plastic, which has a certain degree of elasticity and flexibility and can make adaptive adjustments to a certain extent according to the user's body shape and sitting posture, further improving comfort. In addition, it is equipped with an optional lumbar support at the back. Although its effect is relatively minor, it can also play a certain auxiliary role for some users who have higher requirements for lumbar support. At the same time, it has two levers for adjusting the limit and forward-tilt functions, as well as adjustable backrest resistance. Users can freely adjust the state of the chair according to their own preferences and needs to obtain a more personalized user experience.
