This mesh desk chair combines stylish design with ergonomic innovation. For a healthy, working position you need to sit in a neutral body position; posture with all joints naturally aligned. Traditional chairs put strain on your spine; the most common cause of back and neck pain but with a well-designed, fully-adjustable backrest, headrest and armrest, this can be avoided since you sit with your knees at a 90-degree angle to the floor and your feet firmly planted.
