A dialogue
between
two triangles.

An upright volume meets an inverted one. Their shared diagonal brings two distinct materials into a single, balanced profile.

The cork body rises from the floor to form a backrest. The leather seat opens toward the body, then narrows to the ground. Yi finds its character in this simple relationship: firm and soft, upright and inclined.

Two contrasting volumes define the form. A vertical rear line anchors the composition, while rounded edges soften the transition between surfaces.

Texture
meets
touch.

Textured cork and soft upholstery bring different expressions to the same form.

Cork

In natural brown or carbon black, the rich, granular cork texture gives the body its grounded presence.

Leather & fabric

Sand leather pairs with natural cork. Light grey fabric pairs with carbon-black cork. Both follow the same rounded seat and fine stitched outline.

A small place
to settle.

A broad, gently rounded seat invites a pause. Its low back and compact form give Yi a presence that sits comfortably alongside everyday life.

A renewable beginning.

Cork oak woodland

A renewable material, considered use
and the ambition to last.

  1. 01

    Renewable by nature

    Cork is harvested from bark without felling the tree. The bark regenerates between harvests. Yi places this renewable resource at the centre of its material concept.

  2. 02

    Use material with purpose

    Each of the two volumes has a clear role in the form. Material use and strength will be balanced through prototype testing.

  3. 03

    Design for a longer life

    A lasting form and careable upholstery guide the design. Responsible sourcing, repair options and end-of-life separation remain development goals.

Design intentions; environmental performance is not yet quantified. Cork reference: Corticeira Amorim, “Curiosities”

At home
in the
in-between.

Beside an artwork, beneath a pool of light, or at the edge of a room. A sculptural object becomes part of the everyday.
