Stockholm designer Monica Förster has designed a modular sofa system for Swedish furniture brand Fogia with a padded cover folded over the armrests.

Förster's Retreat system is characterised by the cushions that wrap over the back and armrests of the individual modules and continue all the way to the base.

"The idea has been to give the impression of a padded cover bending softly over the armrest and then onto the seat, giving the feeling of comfort and softness thus creating a warm atmosphere," said Förster.

"We focused on the armrest, creating a strong detail with the wrinkles and movement of the textile," she added. "It is bold but soft and smooth at the same time."

The system for Fogia comprises six low square modules, which come in five different sizes with and without armrests.

Eight suggested configurations range from a simple two-seat sofa to a six-seat corner sofa with a chaise longue extension.

"Retreat is a sofa system for both public and home environments," Förster told Dezeen. "The modules can be combined to create a larger sofa family with lounge parts but the modules are made quite small so that it is also possible to fit into a smaller home environment."

The padding is made from layers of different densities of foam, topped with down for extra comfort. A zip in the textile covers enables removal for cleaning.

"Retreat is a timeless modular sofa made to withstand passing trends," said a statement from Fogia. "Bold yet soft, Retreat is based around an undulating base unit that can be tailored to make areas of cosy reflection or opened up for festivities. The down-filled modules come in a variety of colourways for domestic or contract personalisation."

Fogia launched Retreat at the Stockholm Furniture Fair last month, along with another modular sofa system by Stefan Borselius that was developed from his Tondo chair design for the brand.
