The Cover collection has been designed to work in a range of different rooms and home environments, so "hybridises" aspects of both club armchairs and office swivel chairs.
The Cover chair has a solid back composed of a soft shell that wraps around the seat cushion "in a manner reminiscent of a cape or ankle-length coat," according to Claesson Koivisto Rune.
Meanwhile, its more open front resembles the design of a swivel chair, which is further echoed in a die-cast aluminium pedestal base.
A second base of four aluminium legs is also available. Both options were designed exclusively for this collection, which is produced by office furniture brand Teknion.
"This particular type of design work presents a rare opportunity for a designer, due to the substantial investment needed for tooling, and we have strived to get the detailing of these castings just right," Claesson Koivisto Rune said in a statement.
The form of the chair is repeated in the rest of the collection, which includes an accompanying foot stool, a sofa, and a coffee table that features slightly upturned edges.
"Without compromising on seating comfort, the curved surfaces are kept in check by continuous, sweeping lines, giving the Cover furniture collection a clearly defined appearance not unlike a well tailored coat or blazer," the studio added.
In April 2014, Claesson Koivisto Rune designed a line of chairs that featured winged backrests intended to create "a room within a room".
At the 2015 Stockholm Furniture Fair, the studio unveiled a modular sofa system that would allow sitters to recharge their devices while resting their legs.
The Cover range was launched at Chicago trade fair Neocon, which took place from 15 to 17 June 2015.
Other products launched at NeoCon 2015 include Noé Duchaufour-Lawrance's lozenge-shaped modular seats for Bernhardt design, Hella Jongerius' vividly striped Cork & Felt collection for Danskina, and Studio 7.5's hackable foam office system for Herman Miller.
