This cover includes 9 pieces: 1 frame cover, 2 armrest covers (without side pockets), 3 seat cushion covers and 3 back cushion covers. Norsborg is a modular / sectional series that can be combined with other pieces to create a variety of configurations. This cover will only fit the 3 seater IKEA Norsborg sofa sold from 2015-present. Please be careful not to confuse the Norsborg with the similar looking and sounding Nockeby. If the armrests are enclosed within the sofa frame, see the Nockeby.
