The S3 Pro is designed with women’s body proportions in mind, with enhanced support for the lower back, hips, and overall posture. Its adjustable backrest, seat depth, headrest, and 4D armrests allow for a more personalized fit.
The molded foam seat is shaped to provide more stable, even support for your hips and thighs. Compared with standard foam, it better maintains its shape and support while providing a more substantial sitting feel.
The same height doesn’t always mean the same leg length. A seat that’s too deep can put pressure behind the knees, while one that’s too shallow may not support the thighs properly. The S3 Pro offers 15.4"–17.3" of seat depth adjustment to better fit different leg lengths.
The S3 Pro combines adjustable lumbar support with an adjustable backrest, allowing you to fine-tune the support to your body. It provides a more supportive sitting experience for those who spend long hours at their desk.
The cable-controlled mechanism puts key adjustments within easy reach. You can adjust the seat height, seat depth, and recline while staying comfortably seated, making it easier to find your preferred position.
Not at all. The S3 Pro comes with the necessary tools and instructions and takes about 15–20 minutes to assemble. No special tools or professional experience required.
