The DELI KF243 Mesh Chair is designed to deliver structured ergonomic support and adaptable comfort for professional workspaces. Its ergonomic curved backrest is shaped to provide a comfortable fit while supporting natural sitting posture throughout the day. The chair features 3D lumbar support to enhance lower back stability, combined with breathable mesh fabric that promotes airflow in extended office use. A natural sponge cushion provides balanced resilience and consistent support without excessive compression. For personalised comfort, the 2D headrest offers adjustable positioning, including up to 40° rotation adjustment, allowing users to refine upper back and neck alignment. The gas-lift mechanism provides 7cm seat height adjustment to suit different desk configurations. The backrest supports a 90° upright posture for focused office tasks and reclines up to 125° for more relaxed positioning when needed. The KF243 is well-suited for task-orientated offices seeking ergonomic structure, breathable materials, and flexible adjustability in a modern workspace setting.
