This cover only fits the IKEA Söderhamn sofa series armrest. It includes one piece and attaches with velcro. Bemz Loose Fit Urban covers are designed for a relaxed look, with exposed seams and a hem that trails on floor. Our Loose Fit Urban covers are available in a selection of our fabrics. 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. 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 armrest cover before fitting the Bemz slipcover. Assembly required.
