MARKUS office chair

10-year Warranty. Read about the terms in the warranty brochure. 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. Synchronized 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 synchronized 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. This swivel chair has adjustable tilt tension that allows you to adjust the resistance to suit your movements and weight. To adjust the tilt tension, turn the knob under the seat to increase or decrease the resistance. The high backrest and the curved shape of the chair provide good lower back support and prevent your back from getting tired. You sit comfortably and longer with a relaxed posture. The shape of the armrests provides good support and helps you find a good sitting position. The mesh material of the backrest lets air through to your back during long sitting periods. 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.
