High-Silver fitted grounding sheet, 180x213cm
This will fit a UK Super King mattress. This size is known as "California King" in the US, and "King" in Australia & New Zealand.Made from organic cotton like our standard grounding sheets, but instead of a conductive grid of silver thread, silver yarn is blended into the whole fabric. This means approximately 24% of the total surface area is silver (compared to approx 6% area for the standard sheets).
Visually, a very attractive sleek grey finish that blends well with home decor. The sheets have a connection stud at the edge where the connection cord fits.
The product set includes everything you need for use: the grounding sheet, a 4.6m (15ft) connection cord, and your choice of Earth connection.
Direct skin contact with the sheet is recommended for optimal use, although they will still function through a thin layer of natural fibre bed clothing.
Washing and care instructions
Please note: Due to the nature of silver, the High-Silver products may show some discolouration after long-term use and washing. This does not affect the functionality of the product. We cannot accept returns because of discolouration of the silver as this is simply the nature of the material.
It is good to wash your grounding product. It will not be harmed by washing, in fact it is beneficial. Washing strips body sweat and natural skin oils from the silver keeping it conductive.
DOs
Wash every week or two
Wash in a washing machine with warm water (40°C / 105°F)
Use a liquid laundry detergent (this detergent is our specific recommendation)
Line dry or dry in a dryer on low (up to 65°C / 150°F)
Can be ironed on a low heat if desired
DON'Ts
Don't wash with bleach
Don't wash with fabric softeners
Don't use whitening detergents, oxi-detergents
Don't use detergents with strong fragrances (either chemical or essential oil based)
Don't use dryer sheet fabric softeners
Don't dry clean
Bleach, lotions and oils can tarnish the silver rendering it non-conductive. Fabric softener builds up on the silver and will eventually ruin its conductive properties. Please also check/clean the detergent drawer of your washing machine for residues of other detergents, since many detergents (particularly powders) contain whitening agents which will harm the silver, even in small quantities.
It is advised to wait one hour to use the product after applying oils or lotions to the skin.

Connection for North America
The supplied cord fits directly into the 'Ground' pin of a North American type socket, used in Canada, the United States and Mexico. It can also be used in Central America, the Caribbean, northern South America (Colombia, Ecuador, Venezuela and parts of Brazil), Japan, Taiwan and Saudi Arabia.
Since it is not uncommon for sockets of this type to be missing an Earth connection, this connection option includes a socket tester to verify correct socket wiring. You only need 1 tester per household, so you can choose the "without connection plug" option if you order additional products.
Note that not all outlet sockets of this type have a 3rd pin for Ground. Sockets with only 2 pins cannot be used for grounding, and so a grounding rod must be used instead.

UK: Bahrain, Bangladesh, Botswana, Brunei, Cyprus, Ghana, Gibraltar, Hong Kong, Iraq, Ireland, Jordan, Kenya, Kuwait, Macau, Malawi, Malaysia, Malta, Mauritius, Nigeria, Oman, Pakistan, Qatar, Singapore, Sri Lanka, Tanzania, UAE, Uganda, United Kingdom, Yemen, Zambia and Zimbabwe.
US: United States, Canada, Mexico, Central America, the Caribbean, northern South America (Colombia, Ecuador, Venezuela and parts of Brazil), Japan, Taiwan and Saudi Arabia.
Europe: Austria, Belgium, Bulgaria, Chile, Croatia, Czech Republic, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Indonesia, Italy, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Pakistan, Poland, Portugal, Romania, Russia, Serbia, Slovakia, Slovenia, South Korea, Spain, Sweden, Turkey and Uruguay.
Australasia: Australia, New Zealand, Fiji, Argentina and Papua New Guinea.
Switzerland, Italy, Brazil and USA.
If you have any doubt about whether your mains system is properly earthed, and especially when travelling, we advise using a socket tester to check. The Socket tester (Europe) can be used with this adapter set to test any socket.
Grounding rod kit
If you don't have a properly earthed mains outlet (for example some European houses or a pre-1960s house in the United States), then you can instead use a grounding rod kit to make a connection directly with the ground outside.
The kit consists of a 0.3m (1ft) stainless steel rod with a 12m (40ft) cord. The rod is pushed into the ground outside, which makes a good electrical connection to the Earth. The cord is only 2mm in diameter so it can usually be run through the edge of a window frame with the window closed.
