    Herman Miller

    The highlight of this chair lies in its superb reactivity: the chair adjusts itself to your body shape. Conventional office chairs do not come with high flexibility, so they can be a bit uncomfortable to sit on if you are not of the right body shape. The Herman Miller Cosm Chair is designed to envelop and embrace your body like a warm hug, making sure that you will stay comfortable and healthy all the time during your working hours. The chair will also adapt to each of your movements to ensure that your comfort level remains high even when you have to move around a lot.

    The chair also comes with the Auto-Harmonic tilt mechanism, which helps you to stay in balance no matter what your current tilt angle is. The backrest of the chair is made from well-aerated mesh material, offering superior comfort on hot summer days. The chair also comes with adjustable height, which allows you to customize your sitting experience even further. The armrests will help you to keep your arms comfortable as well, preventing numb arms.

    This chair comes with castors for better movements on all surfaces. This version comes in nightfall colour, which makes it a great addition to a sleek and modern office space. Combining comfort and top-notch aesthetics, the Herman Miller Cosm Chair will help you to get through long hours at work without worrying about back pain or neck pain!
