Meticulously crafted for optimal ergonomics, the AION chair is designed with a keen focus on every detail to cater to your individual needs, whether you're engaged in work, study, or relaxation. Thanks to its elevated high back, you can count on prolonged periods of comfort.


  • Ergonomic Armrests: 5D armrests feature a PU cushion. With a height adjustment range of 70mm, a lateral adjustment of 15mm on both sides, a rotation angle of 25° to the left and right, and an upward lifting angle of 65°, these features address the issue of arm pain caused by prolonged cell phone use.
  • Super Comfortable: The cushion incorporates a high-density non-powder sponge and latex cotton, ensuring a soft, comfortable experience even during extended periods of sitting. The streamlined design efficiently disperses the weight on the hips and thighs, mitigating the risk of poor blood circulation often associated with leg compression and the resulting foot numbness.

Its structure prevents deformation, ensuring you can remain focused and comfortable for extended periods.
