This cover only fits the IKEA Söderhamn sofa/couch section without armrests, sold from 2012 to present. It includes 8 pieces: 1 bottom frame, 1 back frame, 2 seat cushions, 2 back cushions and 2 decorative cushions. Bemz Loose Fit covers are designed to hang looser than our Regular Fit and have a distinctive floor-length drape. 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 the original IKEA slipcover before fitting the Bemz cover. Assembly required.
