To minimize strain on your neck, position your screen so the top of the monitor is at or slightly below eye level. When your gaze is naturally parallel to the floor, your neck muscles don't have to work to keep your head upright. When your head tilts forward, your neck muscles have to support several times the head's actual weight (about 10-12 lbs), which is a primary cause of stiffness and tension headaches.

SIHOO Care Recommendation: We suggest adjusting your monitor height and using our multi-dimensional adjustable headrest. Position the headrest so it fits snugly into the natural curve at the base of your skull. This allows the headrest to absorb the weight of your head, guiding your cervical spine back into its relaxed, neutral alignment.

If your desk or armrests are too low or too high, your body instinctively shrugs to compensate, keeping your shoulder and upper back muscles (like the trapezius) under constant strain. For healthy alignment, your elbows should rest comfortably at a 90-to-100-degree angle. Leaving your arms unsupported forces your shoulders to hold up the weight of your limbs, leading to that burning sensation in your upper back.

SIHOO Care Recommendation: By utilizing our multi-dimensional adjustable armrests, you can bring them to the exact height of your desk. This ensures your forearms are fully supported, allowing your shoulders to naturally drop and release built-up tension throughout the day.

Your spine naturally curves in an "S" shape, but sitting in an unsupportive chair collapses this curve into a "C," placing excessive, uneven pressure on your lumbar discs. To prevent this, your lower back needs continuous, active support. Slouching or leaving a gap between your back and the chair causes your core and lower back muscles to strain continuously just to keep you upright.

SIHOO Care Recommendation: When sitting down, make sure to slide your hips all the way back into the seat pan so your lower back makes full contact with the backrest. Adjust our responsive lumbar support to rest firmly against the small of your back. This system is engineered to hug your lumbar curve even when you shift positions, maintaining pelvic stability and keeping your spine in a relaxed, upright alignment.

If a seat pan is too deep or the wrong height, its front edge acts like a physical barrier, pressing against the blood vessels and nerves under your thighs. This restriction in blood flow is what causes leg numbness, cold feet, and swelling by mid-afternoon. Proper ergonomics require your feet to rest flat on the floor with knees bent at roughly 90 degrees, leaving a gap of 2-3 fingers (about 2 inches) between the back of your knees and the edge of the seat.

SIHOO Care Recommendation: Adjust your seat height so your feet rest flat on the floor (or use a footrest), and utilize our seat-depth adjustment function. Combined with our thoughtfully engineered waterfall-edge seat design, this helps distribute your weight evenly, eliminating pressure points and keeping your lower-body circulation unrestricted.
