Not every sofa has to be a super blocky piece. This curved sofa is proof: Its retro-inspired design with a sinuous, high-low back makes it great for breaking up a room's look. This couch is made with a solid birch wood frame, and has a curving seat and a back that rises to one side, curves down, then rises again for an eye-catching, organic look. The seat is made with pocket spring construction, and has foam-filled velvet upholstery for a blend of support and give.
