Care guide

Washing

Machine wash warm, up to 40°C. Tumble dry low or line dry. Wash every one to two weeks, as you would any fitted sheet.

What damages the conductive fibre

• Bleach — degrades the silver. Never use it.
• Fabric softener and dryer sheets — leave a coating that insulates the fibre. This is the most common way people unknowingly stop their sheet working.
• Oils and lotions — heavy body oils build up over time. Wash more often if you use them nightly.
• Very hot washes — above 40°C shortens the life of the fibre.

Looking after it

Put the sheet in the sheet-care bag before washing, and unplug the cord first. If you think softener or oil residue has built up, two washes with plain detergent and no additives normally clear it. Set-up and use steps are in the Care and use guide.

How long it lasts

The conductive fibre degrades with washing. Washing it in the sheet-care bag, with no bleach and no fabric softener, helps protect it.
