Maison&Objet 2015: French designers Ronan and Erwan Bouroullec have created a range of outdoor furniture with curving slatted surfaces for Danish brand Hay (+ slideshow).

The Palissade collection contains high and low tables, dining and lounge chairs, benches, and sofas, and which are described by the Bouroullec brothers as "strong without being bulky; elegant without being fragile".

The 13 elements in the collection are made from powder-coated steel and will be available in three colours.

"We conceived the collection without a specific context in mind, and hope it will perform well in wide variety of environments: public spaces, cafés, restaurants, gardens, terraces and balconies," said the Bouroullecs, who have recently designed a set of wavy-edged ceramic vases and an outdoor chair with a mesh backrest.

Surfaces are formed from curved slats of the coloured metal, supported by frames comprising tubes of the same material that are cut, bent and welded together.

"The vertical slats offer appropriate comfort in outdoor conditions – air and water will pass in between the anatomically designed slats," said the duo.

The chairs are available in different shapes and sizes, with variations in backrest heights and optional armrests. Cushions are available for extra comfort.

Tables feature flat tops that slope off along the longer sides and accompanying benches are designed to match.

With their slatted seats and angled backrests, the armchairs bear a resemblance to Jasper Morrison's Thinking Man's Chair produced by Capellini in 1989.

The Palissade range is making its debut at the Maison&Objet trade fair, which kicks off today at the Nord Pillpinte exhibition centre outside Paris.

Continuing until 8 September 2015, this edition of the biannual event will also include the launch of a ballpoint pen that can digitally record and store notes.

Hay recently announced a collaboration with fashion brand COS, and the two companies worked with Spanish designer Tomas Alonso to produce a pair of tables.
