The design features thin wooden legs, which appear to rest against the sides of the seats.
Longer elements hold the back rests and optional integrated side tables, in a range of heights and sizes.
"The legs that appear to have little to do with the frame are actually the pillars that can be anchored to it and grouped in multiple compositions," said a statement from Moroso.
Standard two and three-seater sofas can be combined into different arrangements.
Flat and corner back cushions can be added or removed to encompass or separate sections.
A single exaggerated seam runs around the edges of the upright cushions, which are upholstered in wool jersey along with the seats.
The sofas are available in a range of colours with matching throw cushions.
Moroso is showing the designs at the Salone Internazionale del Mobile, Hall 16 Stand 22/29, in Milan until 13 April.
