Small social circles can grow into parties of plenty when you have furniture that offers abundant space for seating and entertaining. Enter the Costello sectional. This loungy piece lets everyone sprawl out in style, with its substantial span and streamlined design, which comes together with a tufted tight back, track arms, block feet and welted seams. Hip and versatile, its woven dark gray upholstery complements the room’s contemporary coastal look of geometric prints coupled with by-the-sea accents, like rope stools, steel lanterns and glass bottles.
