Eve overview

Overview

Eve™ by Leo Cancer Care is an innovative upright treatment chair designed to enhance comfort, stability, and precision in modern radiotherapy environments. Created to support patients in a natural seated position rather than the traditional supine posture, Eve helps improve the overall treatment experience by reducing discomfort and promoting a greater sense of ease during care. Its ergonomic, highly adjustable design accommodates a wide range of patient needs while enabling accurate and repeatable positioning for advanced radiation treatments. Blending patient-centered design with clinical practicality, Eve represents a modern approach to cancer care that prioritizes both human comfort and treatment accuracy.
