New York 2016: Brooklyn design studio Fort Standard has debuted a cabinet crafted from stone slabs and a chair made solely of leather as part of its latest furniture collection (+ slideshow).

The Qualities of Material collection celebrates the designers' preferred natural materials — stone, wood and leather — with each used to create entire pieces.

Fort Standard founders Gregory Buntain and Ian Collings were led by a more experimental approach than on previous projects.

"We've been interested in evolving that conversation about how we can push these materials further and do different things with them," Buntain told Dezeen.

A highlight of the collection is the monolithic Relief Stone Cabinet, made from soapstone and sat on a maple wood base.

"[Soapstone] has some really unique qualities," said Buntain. "The one we chose to focus on was its workability.

"We took one large slab and basically wrapped it around the entire panel, so you can see the veins come through from one panel to the next."

To maintain the material's strength while removing some of its weight, the designers milled a triangular relief pattern into the doors.

For the collection's occasional chair, they used stacked leather – similar to the sole of a shoe – for the seat.

The legs and backrest were formed by wrapping the vegetable-tanned leather around tubes to create cylinders that were soaked in glue, then bent around moulds and cooked in an oven.

The Qualities of Material collection also features a coffee table, dining table and bench made from hundreds of thin, hard maple wood slats. The sections are fused into triangular prisms, then assembled to form seats, legs and table tops for the furniture.

Fort Standard's previous designs have included aluminium bowls raised on slim piers and a set of stone-shaped wooden building block toys.

The range debuted at New York's Collective Design Fair, taking place this week from 4 to 8 May 2016 at Manhattan's Clarkson Square venue. Also on display at the fair is a range of furniture that traces the motion of moving elements by Nendo.

Elsewhere during the citywide NYCxDesign festival, running until 17 May, Lambert & Fils is debuting a collection of pendant lighting.
