With a single seat cushion and softly rounded right angles, Delta is all smooth surfaces. The 2-seater sofa 175 gets its comfortable slant from soft down-fill and a multi-layer seat on a webbed frame. Large back cushions leave space to fill in with the smaller throw-pillow style as desired. And the built-in steel frame easily allows for corner or inset-foot placement. Please note, Delta cushions have to be ordered separately. If cushions need to be added to the order please let us know the size and quantity.
