Quick answer

For a large or open-plan room, a U-shaped or multi-seat modular sectional (10 to 12 seats) fills the space and defines the lounge zone without looking marooned. Because the pieces are modular you can scale the run to your wall length. Confirm the full footprint and seat count on Monvane before ordering.

In a large or open-plan room, an undersized sofa looks marooned. A U-shaped or multi-seat modular sectional does the opposite: it defines the lounge zone and pulls the whole family together. Because the pieces are modular, you can scale the layout to the wall length you actually have. Start with the Monvane U-shaped range and use our how many seats guide to size it.
