Nasa – perhaps the most comfortable chair in the world. Nasa boasts a simple, timeless design combined with patented Century foam. Its organic form and personalised adjustment options make it uniquely comfortable. A stepless tilt function provides the best possible posture in all positions. We adjust the chair’s height, tilt and backrest according to your needs, to give you maximum and completely individual seating comfort. The robust Aston stitching and details on the armrests and footstool reveal craftsmanship of the highest quality.
