This cover only fits the IKEA Söderhamn sofa bed, sold from 2012 to 2015 (now discontinued). It includes 8 pieces: 1 bottom frame, 1 back frame, 2 seat cushions, 2 back cushions and 2 decorative cushions. The bottom frame measures 200 x 99cm (be careful not confuse it with the 3 seater sofa model). The IKEA Söderhamn series is modular so the various sections of the seating series can be connected together in different combinations or used separately as standalone pieces. The configuration is determined by you. To allow for this, our covers for Söderhamn models do not come with preset holes for assembly. If you have a connecting configuration, cut a small slit in the cover at connection points to accommodate the bolts. Remove original IKEA slipcover before fitting. Assembly required. Bemz Loose Fit covers are designed to hang looser than our Regular Fit and have a distinctive floor-length drape.
