It uses high-quality nylon material combined with PU coating. This material combination effectively resists daily wear and tear and prolongs its service life. Its "5D" design means that the armrest has excellent support and flexibility in multiple dimensions, which can perfectly fit different body shapes and sitting postures, providing a full range of comfort. Particularly outstanding is its adjustable and foldable function. Users can easily adjust the height of the armrest or fold it up according to personal preferences or space requirements. The armrest design realizes the function of rotating inside and outside. This feature not only promotes multi-angle support for the body, but also facilitates users to switch postures freely when resting, working, or entertaining, reducing physical fatigue.
