This cover includes 14 pieces: 1 frame (for the entire 2+3 Karlstad sofa), 2 armrest covers, 6 backrest and 5 seat covers. Karlstad is a modular series now discontinued at IKEA. It requires assembly to fit covers (legs and armrests need to be removed first then reassembled after cover is on). When facing the sofa, the 2-seat section is on your right. This cover will only fit the IKEA Karlstad sofa.
