With a magnetic memory foam headrest and a 135° recline system, every detail is tuned for comfort that lasts.

• 24° Pop-Out + 4-Way Adaptive Lumbar Support: Kaiser 4’s advanced lumbar system combines a 24° pop-out extension with adjustable height and depth. The internal 4-way support lets you customize spinal alignment using dual side knobs, while the elastic locking gas spring allows you to lock in your ideal lumbar angle. Built with a full-metal mechanism that withstands up to 2500N, it delivers unmatched back support for long gaming or working sessions.
• Re-engineered 6D Armrests with Better Control: The upgraded 6D armrests offer enhanced customization with three pivot hinges and intuitive controls. Easily adjust height, tilt, slide, and rotation to relieve pressure on elbows and wrists - whether gaming, typing, or browsing. A groove design on the front edge provides a firm grip, making every adjustment effortless and precise.
• Breathable Linen Comfort for All-Day Use: The linen fabric offers a soft, airy texture that stays cool and dry, even during long hours of sitting. It naturally regulates temperature and wicks away moisture, helping you stay comfortable through every gaming session, work call, or relaxed moment.
• Magnetic Memory Foam Head Pillow: The magnetic head pillow moves up to 20cm vertically, letting you position it exactly where you need it. Filled with elastic cold-cure memory foam, it contours naturally to your head and neck, providing cool, lasting support through hours of gaming or work.
• Wide High-Density Cushion + Recline & Rock: A sloping, high-resilience seat cushion reduces pressure on your thighs and hips. Combined with a 135° recline and 15° rocking function, plus a reinforced aluminum wheelbase and heavy-duty tilt mechanism, Kaiser 4 delivers ergonomic relaxation and sturdy support for every posture.
