HATTEFJÄLL Office chair with armrests, Gunnared green/black

Suitable for business use. This ergonomic office chair has lots of functions that allow you to easily adapt the chair to your body. Height-adjustable seat allows you to adjust the height so that back and legs are at a 90° angle. With automatic tilt tension, your body weight determines how much resistance the backrest offers. This counter-pressure helps you keep an active posture in your chair. Synchronised tilt mechanism allows the chair to move with you. The backrest moves more than the seat when you lean back, so torso/hips open up. This improves circulation and keeps energy levels up. As you recline, the synchronised tilt mechanism allows feet to stay on the floor while your gaze remains straight ahead. Your chest stretches without adding pressure on thighs, improving circulation. Adjustable seat depth enables proper back support and even weight distribution across the seat cushion. This prevents circulation from being cut off at the knees and reduces knee pressure. Backrest can be adjusted to 5 different heights to provide support in all the right places and helping your body to maintain a naturally good posture. Adjustable lumbar support helps maintain the correct posture while sitting which reduces strain on muscles on your lower back. Height and width adjustable armrests enable a relaxed position for arms and shoulders and reduce the risk of tension, fatigue and pain in the shoulders and neck. Tilt lock allows you to adjust the tilt and lock it at 5 different positions, from low to upright. A safety function locks the castors when no one is sitting in the chair and keeps it securely in place when you stand up. The castors are designed to provide ease of movement and maneuverability on both carpeted and hard floors as well as on uneven surfaces.  Adjustable seat height. Adjustable seat depth.
