   • Design Features: Specifically designed for women, with a pink color scheme and macaron gradient backrest, offering high aesthetic appeal, suitable for users who value the beauty of their office environment.

II. Key Points for Selection

1. Size Fit

   • Seat Height: Ensure feet can naturally rest on the ground, avoiding suspension or pressure on the thighs.
   • Seat Depth: Maintain a 2-3 finger gap between the back of the knee and the edge of the seat to prevent blood vessel compression.
   • Backrest and Headrest: Taller users should pay attention to the adjustment range to ensure neck and lumbar support.

2. Sitting Posture Habit Matching

   • Upright Sitting: Prioritize chairs with adjustable lumbar support, breathable seat cushions, and strong armrest support (such as SumLush's BackFit system).
   • Reclining Rest: Pay attention to the backrest range of motion (such as 135° recline) and the base adjustment method (such as infinite locking function).

3. Material Selection

   • Mesh: Excellent breathability, suitable for users who sweat easily or in southern regions, but be mindful of elasticity degradation.
   • Sponge Cushion: Offers a variety of softness and wrap-around feels, suitable for users seeking a soft touch, but requires regular cleaning to prevent sagging.

4. Functionality and After-sales Service

   • Weight Capacity: Should cover the user's weight to avoid long-term overloading leading to structural damage.
   • Adjustment Functions: Check if the headrest, armrests, lumbar support, etc., support multi-dimensional adjustments to adapt to different scenarios.
   • Installation and After-sales Service: Prioritize brands that provide detailed installation videos and long warranty periods (such as over 3 years).
