Your posture doesn’t start at your shoulders.
It starts where you sit — with your pelvis.
As a surgeon, ergonomics isn’t an extra. It’s essential.

At Rini, we design surgical chairs that support the body from its foundation up. A slightly forward-tilting seat helps your pelvis find its natural position, encouraging the lumbar spine to maintain its healthy curve.

Why does this matter?
Because when your pelvis is aligned, your entire spine follows — reducing fatigue, relieving pressure, and helping you stay focused through long procedures.

✔️ Better posture
✔️ Less strain
✔️ More control
✔️ All-day comfort

🧠 Ergonomics isn’t an extra. It’s essential.
🔧 That’s why every Rini chair is engineered to work with your body — not against it.
