This cover includes 4 pieces: 1 frame cover, 1 seat cover and 2 armrest covers. All cushion covers are reversible. Bemz Loose Fit covers are designed to hang looser than our Regular Fit and have a distinctive floor-length drape. Lovely ties are used instead of zippers. You have chosen the Tomelilla model that measures 78 cm high at the back.   To check you have chosen the correct size, measure lengths A and B according to the illustration. This will confirm if your armchair requires a Standard or Small size. Begin measuring length A 7 cm below the top of the chair. Standard size: A = Approximately 20 cm , B = Approximately 20 cm Small size: A = Approximately 12 cm , B = Approximately 16 cm Please note! If your model measures somewhere in-between (for example, A measures 12 cm and B measures 20 cm, or A measures 20 cm and B measures 16 cm), please select Standard size.
