This cover only fits the IKEA Vimle 3 seater sofa with removable fabric covers. It includes 10 pieces: 1 back frame cover, 1 front panel cover, 3 seat cushion covers, 2 armrest covers and 3 backrest cushion covers (reversible). The Vimle series is sectional/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 and Bemz makes covers to fit any configuration you've chosen. The Vimle 3 seater sofa comes with armrests. Remove the original IKEA sofa cover before fitting the Bemz slipcover. All Bemz cushion covers for Vimle come with zippers and all other pieces are attached with velcro. Assembly required. Please note that the armrests covers for this sofa are ordinary size (15 cm) and not the wider size (22 cm). Covers for the wider armrests (22 cm) are sold separately
