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.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.
