Office Chair, Boss Chair Movement Features
The 'movement' features of office chairs and boss chairs from different brands are distinctive and can meet diverse usage needs.

The 'movement' feature of the Livorno S350 office chair is primarily reflected in its armrest design. It adopts a star-orbit circular armrest with a unique shape that better fits the elbows, providing ample support and allowing the user's elbows to remain comfortable during office work, reducing fatigue caused by prolonged support and enhancing the overall user experience.
The 'movement' features of the Yongyi X5Pro lumbar support chair are quite rich. The Domino lumbar support system is a major highlight, capable of quickly responding to changes in sitting posture to ensure that the waist does not remain suspended during prolonged sitting, providing continuous support to the waist. The slidable and lockable lumbar support can slide to track and lock in place, allowing for flexible adjustments based on the position of the waist. The 6D magic armrest is highly adjustable, with functions such as lifting, rotating, moving forward and backward, and flipping, enabling it to accommodate different sitting postures and meet diverse usage scenarios. The 150-degree recline locking function supports large-angle recline and can be locked in different positions, allowing users to find a comfortable angle during rest. The seat depth is also adjustable, allowing for adjustments based on leg length to ensure that the legs remain comfortable.
The 'movement' features of the Igrow Alpha ergonomic chair are even more comprehensive. The full-process dynamic tracking system redefines the relationship between the person and the chair. The motion-sensing backrest gliding technology, with its dual-rail elastic motion, customizes gliding trajectories for different body types, better adapting to the physical characteristics of different users. The lumbar support adjustment bracket is a curve-guided sliding rail, allowing the lumbar support to move backward synchronously along the curved trajectory during recline, aligning with the natural curvature of the spine and effectively protecting the waist. The 8cm adaptive traction lumbar support fits snugly against the lower back whether sitting upright or leaning forward, providing comprehensive lumbar support. The neck support has 8 levels of forward push locking, combined with up and down adjustment and dual-angle rotation, meeting the needs of different neck postures. The armrests can move up and down, left and right, and rotate 360 degrees, offering flexible usage. The wired control chassis can be operated without bending over, with 4 levels of recline locking, and the gravity chassis automatically adjusts the recline resistance based on body weight, making usage more convenient and comfortable.
