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 85 cm high at the back.     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.
