Interstuhl Joyce JC1N1, ergonomic office chair with 4D armrests

Whether you work in an open space or in a private office, the Interstuhl Joyce JC1N1 ergonomic office chair delivers seating comfort that holds up across a full working day. Designed by Daniel Figueroa for Interstuhl, it pairs a refined silhouette with advanced ergonomic technology, in a chair built to withstand intensive daily use.

At Wooh, we equip Belgian SMEs that want to offer their teams a healthy workstation without falling back on the generic chairs everyone has already tried. The Joyce JC1N1 is one of the models we recommend to our clients for this kind of demanding use.

Ergonomics that adjust to each user

The Joyce JC1N1 features a lockable synchronous mechanism with multi-step weight adjustment. It adapts precisely to each user’s build and weight, providing consistent support throughout the day. The backrest is height-adjustable and, combined with a firmly padded ergonomic seat, holds the lower back exactly where it needs to be.

The 4D armrests adjust in height, width, depth, and pivot inward and outward. Their soft pad surface absorbs pressure points and reduces tension in the shoulders and neck, two areas where poor adjustment quickly creates discomfort.

Materials and finish

The signature stitching along the sides underlines the chair’s premium character, without any visual excess.

Thanks to Interstuhl’s wide range of fabrics and colours, the Joyce JC1N1 can be customised to match your visual identity or the atmosphere of your offices. The model is directly available in black, with other colours available on request with a lead time of approximately 5 weeks.
