Patricia Urquiola straps cushions to Roll chair for Kettal

Spanish designer Patricia Urquiola has attached two long cushions to the back of this outdoor chair with coloured straps.

The Roll chair's back support is formed from padded horizontal strips that look as if they've been wrapped up and attached like roll mats tied to a backpack.

"This ironical intervention on the conventional upholstery converts a regular backrest into two independent 'wraps' connected by colourful straps," said a statement from Kettal.

Two pins at the top of the vertical supports on either side of the back hold the straps in place. These can be pulled out so the cushions can be removed and packed away.

A powder-coated aluminium frame supports the upholstered elements, which are available in a range of bright colours.

"A graphical aluminium structure frames the protagonist of this chair, the cushions," said the brand.

The seat cushion is covered in a semi-transparent fabric that is suitable for outdoor use. The straps also come in a variety of hues to contrast with the upholstery.

Urquiola designed the stand for Kettal at this year's Salone del Mobile furniture fair in Milan last month. She has previously created a seat woven from nautical rope for the Spanish brand.

Other products the designer launched in Milan this year included a collection of iridescent glass furniture for Glas Italia. During the event, she was one of a series of designers that spoke out about the intrusions of visitors and journalists at the fair.
