Triennial is a modular family of chairs that will allow you to create the ambience you have envisioned. The most striking feature of Triennial is its shell, which is made out of two fully upholstered parts. The 'separate' backrest cushion fits snugly against the seat. 

Sitting high off the ground on the Triennial bar stool is an adventure. The slender wire frame gives the stool a light-footed appearance. The comfortable seat makes the stool suitable to sit on for longer periods of time. The low backrest allows for movement while seated but also gives you the support that makes Triennial High so comfortable.

Create an ambience of your own

The Triennial High with low backrest comes with either a 65 or 75 cm high frame. In addition, there are plenty of colours and fabrics to choose from. You can make endless combinations to create the perfect stool for you.

Waste as a resource

The manufacturing process of Triennial has become so efficient that we can even use the excess material. Nothing goes to waste! The excess material is sorted by colour and is then processed into acoustic panels. This means that, if you were to acquire Triennial chairs, you can also give the excess material of the production process a place in your office. With the added benefit of better acoustics and remarkable visual effects.



Gispen believes firmly in its circular model, which is why we already took account of returns and reuse of components and materials when we designed Triennial. Gispen stands for high-quality products and takes responsiblity for their entire lifespan, while reducing waste production for as far as possible. When a Triennial product is at the end of its lifecycle, we will give it a new function or refurbish it into a product that is as good as new.

Make Triennial even more sustainable and opt for a durable fabric. We work with many fabric suppliers, of which some use hemp-based or recycled plastic materials.
