Grounding Original Earthing Bedsheet. This sheet is the flat sheet from groundingofficial.com that wraps around the mattress rather than replacing your fitted sheet. 90x270cm. Includes the sheet, two cords, and outlet tester to ensure your outlets will enable your sheet to be grounded, allowing you to receive the many benefits earthing has to offer! Perfect to take with you traveling as you just wrap it around the mattress or can lay it on top. Brand new, never used.
