Swopper active chair, dark grey Musa fabric, white base, castors

The Aeris Swopper active chair combines timeless design with a distinctive approach to sitting. Ideal for offices and home workspaces, this ergonomic chair offers freedom of movement and encourages changes in sitting position. Its recognisable spring mechanism keeps sitting dynamic, allowing small movements even while you concentrate on your work. At the heart of the Swopper is genuine Aeris 3D technology. A joint positioned close to the floor enables movement forwards, backwards and sideways, while the spring adds the Swopper’s signature vertical motion — a gentle, responsive bounce. This freedom encourages you to vary your posture and engage your body in maintaining balance. The padded, convex seat supports an open sitting posture. With no backrest or armrests to restrict movement, you have room to move freely. Stepless seat height adjustment helps you find the right position for your workspace, while the spring tension and lateral flexibility can be adjusted to suit your body weight and preferred sitting feel. The base with castors makes it easy to move the chair around your workspace and into position at your desk. This model offers the same familiar three-dimensional Swopper movement and individually adjustable sitting experience. Dark grey Musa polyester upholstery is paired with a white base and spring. The contrast between the dark seat and light frame highlights the chair’s distinctive shape and complements both office interiors and home workspaces. The Standard spring is designed for users weighing 50–120 kg. Use the Swopper as your main active office chair or alongside a conventional office chair to alternate your sitting style throughout the day. It brings variety to desk work and makes movement a natural part of your working routine.
