An earthing fitted sheet stretches nicely around your mattress and ensures that you have perfect contact with it all night long. A flat sheet usually dares to shift during the night, although it is best to apply both under your own top sheet.For a small additional cost, an earthing fitted sheet is recommended over a flat sheet. Flat sheets, on the other hand, are easy to take with you when you travel or when you sleep with third parties, as they are less dependent on the size of your mattress. They are therefore also perfectly suitable for 'growth' cots.For daily use, a grounded fitted sheet to the size of your mattress is the perfect solution.
