Strain / Unstrain chair

Strain and Unstrain are like twins in the Strain collection but convey their own typology. Both chairs have a universal flair with their ergonomic design of a solid wood seat that can be additionally upholstered with leather or fabrics for superior comfort. They create the perfect solution for interior residential or public spaces.

The ‘strain’ theme continues in the solid wood and ergonomically shaped saddle-like seat of a barstool, thus offering various ways of dynamic seating. Visually light and uncustomarily slender, the collection further consists of tables of various heights and finishes, and two newcomer chairs – Strain and Unstrain. Similar in even more simplified Strain form, their difference lies in the key family feature of intertwisting leg junctions. While Strain retains the twist, which provides the necessary construction stiffness, Unstrain releases it, resulting in the a contemporary interpretation of the 1950s universal chair, which is easily stackable.

The Strain collection’s distinctive character evolves from the highly strained materials. However, the leg junctions are the main signature of its design language, achieved through the intertwined steel tubes which basically harden the whole construction. The easy chair, the collection’s founding product, enhances this concept throughout its form, created by tightly stretched leather over the metal seat shell. Its remarkable comfort is down to the material’s elasticity, which has additional support from the lumbar cushion. The Strain collection’s aesthetic results from the fusion of high-end technology and refined craftsmanship.
