The mattress cover has piping on the seam all around the top and bottom, the same fabric throughout the cover, zipper on one long side and is reversible. Bemz mattress covers are made using the same fabric front, back and along the edges, making it reversible. You can add decorative piping around the edges, as an extra detail if you wish. The covers have a robust zipper along one side for easy removal. Measures 90 x 200 cm H6cm Our mattress covers fit most common mattress sizes in thicknesses from 4 cm to 14 cm. We also offer covers in sizes suitable for children. If you have the popular IKEA daybed/sofa Hemnes, we recommend a 80x200 cm cover to completely transform that piece of furniture.
