      Equipped with the most high-end TUV certified level 4 hydraulic air rod, the Joza series provides a smooth and silent lifting experience.

      Rest on Joza Series' Full Height Recline-able Backrest*that can recline up to 120°, lock/unlock via the chair mechanism.

      Joza Series' Height & Tilt-Adjustable Headrest gives users the optimal head & neck support regardless of their height.



      Joza Series' headrests and back is upholstered with Breathable Mesh, providing elastic back support that allows body heat and humidity to be released effectively while seated, keeping you fresh at all times.

      Joza Series' Breathable Seat base padded with high-density soft foam allows long sessions of working even in hot and humid weather.


      The S-shaped design of the backrest, paired with the included Lumbar Support Pillow, accommodates to the natural curve of the spine preventing any unwanted spine compression. 

      The Fixed-Height PU Coated Armrests have the standard durable support, it has harder top surface compared to the other models.


      The Joza Series' Alloy Coated Wheelbase is designed to visually fit an office setting. The PU Dual-Wheel Casters are gentle on most surfaces, gliding smoothly while minimizing noise in the office.

      Keep it Dry

      Vacuum any dirt off your chair. Remove remaining dirt with warm soap and water. If stains persist, gently dab the area with a spot cleaner. DO NOT rub or scrub.

      Keep it Clean
      Light stains can be removed with textile cleaner or a sponge damped in water or a mild soapy solution, remember to wipe it dry with a clean cloth afterwards.

      Avoid High Heat

      High temperature such as long exposure to direct sunlight would damage the the top coating of the mesh.

      Avoid Sharps Objects
      Although Scratch-resistant, sharps objects could still pierce and damage the mesh at certain point.
