WHY ARE IMMUNOCTEM MATTRESS COVERS EQUIPPED WITH A THREE-SIDED OPENING?

All IMMUNOCTEM anti-dust mite mattress covers are equipped with a high-quality zipper (YKK brand) on three sides (two widths and one length) to facilitate the installation of the cover around the mattress. In order to optimize the protection against dust mites, you will find a wide strip of fabric under the zipper.

Creating a three-sided opening requires impeccable finishing and waterproofing that is impossible to achieve. High-end zippers are expensive. Many cover manufacturers cut corners on this, offering only one opening on every other side, or even just one side! Imagine trying to fit a full-cover mattress cover under such conditions.
