This cover includes 7 pieces: 1 frame cover, 2 seat covers, 2 back covers and 2 inner armrest covers. All cushion covers are reversible. The cover will only fit the Nockeby 3 seater sofa from IKEA and not similar models. Be careful not to confuse with the IKEA Norsborg, which looks and sounds similar. You can tell you have a Nockeby if the armrests are enclosed within the sofa frame. Sold at IKEA from 2015-present.
