Your new mattress cover will come around the core of your current mattress, so it is important that you measure the height of the core. And of course know your mattress size, for example, 90x200. The most commonly used covers are made for 2 types of mattress cores. The 14-15 cm high cores and the 16-18 cm high cores. These are mattresses with a height of 15 to 17 cm. And the height from 18 to 20 cm. A difference of a few centimeters does not matter, the mattress cover is flexible and will therefore stretch neatly around the core. It is very easy to place the cover over the existing mattress core. You put your mattress upright on its long side and put the unzipped cover over the long side around it, then you put the mattress back on its flat side on the (clean) floor, and zip the cover closed over 3 sides. The mattress cover is anti-allergic. And also durable, washable at 40 degrees (not in the dryer), very good moisture-regulating properties.
