This cover only fits the IKEA Söderhamn 1 seat section without armrests, sold from 2012 to present. It includes 5 pieces: 1 bottom frame, 1 backrest, 1 back cushion, 1 seat cushion and 1 decorative cushion. 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, Bemz covers for Söderhamn models do not come with preset holes for assembly. If you have a connecting configuration, cut a small slit in the furniture cover at connection points to accommodate the bolts. New IKEA furniture can be purchased without slipcovers. If you are buying this as a replacement cover or additional cover, remove the original IKEA Söderhamn 1 seat section cover before fitting the Bemz slipcover. Assembly required. Bemz Loose Fit covers are designed to hang looser than our Regular Fit and have a distinctive floor-length drape. The Loose Fit covers are available in a variety of fabrics.
