The two pieces of furniture both feature low profiles and rounded seats, which give them their distinctive form. The chair features a black powder-coated steel swivel base, while the sofa sits close to the ground on small feet.
They are upholstered in Kvadrat's Ria textile – a patterned and textured fabric designed by Raf Simons, which is made from wool, viscose and nylon.
Malouin, who is originally from Canada but currently based in London, first unveiled his Group armchair in New York earlier this year, during the ICFF fair. He then revisited the design to create the armchair, which debuted at London Design Festival last week.
"The original group chair was destined for public areas such as clubs and lounges – its swivel base and small footprint made it ideal for these environments," the designer told Dezeen.
"Meanwhile the sofa is aimed for the home sector," he added. "It was designed for its users to slouch on instead of sitting up straight."
Both seats come with a frame of solid beech and birch plywood, while the cushions are made using feathers and foam. They are produced by Coakley and Cox, a manufacturer based in Norfolk, England.
This is the first collaboration between Malouin and SCP. The brand was introduced to the designer when he was creating his Gridlock lighting for Roll & Hill, which is now a product on sale in SCP's London stores.
