Under a fitted pad I understand something else. The finished product - ensure high quality - was provided with four Eckgummis quilt for me. By now also greater support on our soiweso very good mattress (Metzeler Cubix platinum), the "hardness", ie sleeping comfort altered significantly.

The designation duvet was incidentally on the packaging.
