The DELI KF236 Mesh Chair is ergonomically designed to provide structured support and breathable comfort for modern office environments. Its S-shaped curved backrest follows the natural contour of the spine, while the extra-large lumbar support enhances lower back stability during extended sitting periods. The chair features highly breathable mesh fabric to promote airflow and maintain comfort throughout the workday. A multidirectional adjustable headrest offers 5cm height adjustment and 30° rotation, allowing users to customise upper back and neck positioning. The 90° foldable armrests provide flexibility and convenient desk access when needed. An adjustment lever located on the lower right side of the seat cushion allows users to unlock and recline the backrest, then lock it securely in the desired position. The rotating base spring includes a tilt tension control knob to adjust reclining resistance. The seat is made with original rebound sponge designed to relieve pressure and maintain its shape during prolonged use. The KF236 is well-suited for task-focused offices seeking ergonomic structure and adaptability.
