Sofa with Left Arm Rest. The blocky style of the Cloud collection makes it the ultimate for modish modularity. Create your own corner sofa with our modular pieces. The double sofa with arm is the final piece of your corner sofa. Alternatively, use this modular sofa as a stand alone piece with its open-end as a chaise longue. Large enough to seat three people or ideal for one to kickback. The Cloud collection includes a full range of modular pieces: corner section, double sofa with right hand armrest, single bench-seat and double bench-seat, available independently or in preconfigured sets, as well as complementary chaise longue and armchair units.
