Lying Flat Office Chair Armrests
The armrests of lying-flat office chairs come in various types, commonly including dual-axis magic armrests and 4D armrests, which offer multiple adjustment functions to suit different usage scenarios and needs.

Dual-axis magic armrests: Represented by the flagship model from Gaotian Sai Lei, these armrests are rich in functions and flexible in adjustment. They support rotation of the armrest surface, allowing users to adjust it to a comfortable angle based on their arm placement habits, whether it's for natural arm hanging during upright office work or for arm bending support during semi-reclined rest. The height adjustment function enables the armrests to adapt to the elbow height of users of different heights, preventing arm suspension or excessive bending due to overly high or low armrests, thereby reducing shoulder and arm fatigue. The forward and backward sliding adjustment facilitates users in adjusting the distance between their arms and body in different sitting positions. For example, when operating a keyboard or mouse, the armrests can be moved forward for better arm support; when relaxing, they can be moved backward to increase body movement space. The central axis rotation function further enhances the flexibility of the armrests, allowing users to rotate them to obtain the best support angle according to different devices used, such as computers or tablets, improving comfort and efficiency of use.
4D armrests: The 4D armrests equipped on lying-flat office chairs offer all-around adjustability. The forward and backward adjustment meets users' needs in different work states, such as moving the armrests forward to be close to the body during focused work and moving them backward during relaxation. The up and down adjustment adapts to the elbow height of users of different heights, ensuring effective arm support. The left and right adjustment allows the armrests to better fit the body contours of users, providing more personalized support. Additionally, the function of clamping items on the armrests increases usage diversity, enabling users to clamp small items such as mobile phones or notebooks on the armrests for easy access at any time. The adjustable height further enhances the practicality of the armrests, allowing them to be adjusted to a suitable height for both sitting and lying positions, providing comfortable support for users.
