Y 4D Triumph Universal Mini chairs
The back support adjustment mechanism makes it possible to adjust the height and depth of the lumbar support, providing support for the spine regardless of the user's body weight and height, which makes it possible to spend a comfortable time working or studying. 4D-adjustable armrests can be adjusted to the individual features of the person sitting (height, angle of rotation, forward movement, backward movement, distance between the right and left elements)
