Watch the Elysia tutorial videos and learn how to properly adjust the chair to achieve maximum comfort. From the movements of the synchronized mechanism to the use of armrests, headrest and seat slider, each guide shows you how to configure your chair at its best. Ideal for those looking for ergonomic task chairs designed for operational work, these videos clearly explain all the features that make Elysia a perfect balance of sustainable design and functionality.
Syncron mechanism with seat slider MEC-09
Elysia was developed to meet the real needs of contemporary workspaces, where ergonomics, flexibility and performance must coexist seamlessly. Its latest-generation synchronized mechanism ensures smooth, proportional movements between seat and backrest, promoting a dynamic posture that is essential for operational work requiring focus and physical comfort throughout the day.
The mechanism includes a wide range of intuitive adjustments:
Backrest tilt with multi-position locking
Personalised tension adjustment based on user weight
Seat depth adjustment for correct leg support
Multi-adjustable armrests (height, depth, rotation)
Adjustable headrest to relieve cervical tension
Each element contributes to a complete ergonomic system tailored for professionals seeking ergonomic task chairs that improve daily wellbeing and performance.
The aluminium structure connecting seat and backrest creates a fluid, continuous line that enhances both stability and aesthetics. With two finishes available—polished aluminium or total black—Elysia fits effortlessly into executive offices, meeting rooms and contemporary environments.
The collection also includes the medium-back version and the visitor chair with sled frame, providing visual coherence across the workspace. Each model reflects Sitlosophy’s approach to sustainable design and functionality, using refined materials and optimised production processes for long-lasting performance.
Elysia is not merely an elegant executive chair, but a product that interprets sustainable design and functionality in a concrete way. Every component is designed to guarantee durability, easy maintenance and reduced environmental impact, without compromising aesthetics or comfort.
The choice of aluminium—a highly durable and recyclable material—for the main support highlights the commitment to creating long-lasting products. High-quality upholstery materials further extend the chair’s lifespan, while the modular design ensures that maintenance or part replacement remains simple and efficient.
From an ergonomic perspective, Elysia stands out among ergonomic task chairs thanks to its synchronized mechanism, which promotes dynamic posture, reduces fatigue and improves concentration—ideal for operational work.
The colour and finish options allow the chair to adapt to different workplace identities: polished aluminium for a timeless professional look, or total black for a bold, contemporary style. The visitor version completes the range and ensures aesthetic coherence throughout the space.
Choosing Elysia means investing in durability, comfort and long-lasting performance. A chair that brings together ergonomics, aesthetics and sustainability to elevate everyday work experience.
