One honest note. Most people don't notice much in the first week. Many notice nothing for two or three weeks. A few notice nothing at all — which is exactly why the trial is 90 nights and not 30.
A fitted sheet woven through with conductive silver fibre, connected by cord to the ground port of a standard earthed outlet. The conductive threads run across the sleeping surface, so bare skin — feet, arms, shoulders — completes the path to earth while you sleep.
What it measurably does. Indoors, your body floats at somewhere between a few hundred millivolts and a few volts relative to the earth, induced by the wiring in your walls and the cords around your bed. Connected, that collapses to near zero. This is ordinary electrical engineering, not a claim you have to take on faith.
Looking after it. Silver-threaded fabric can lose conductivity over time with body oils, detergent residue and fabric softener. Wash it in the free sheet-care bag, skip the softener, and follow the Care and use guide.
What we don't claim. This is not a medical device and is not intended to diagnose, treat, cure or prevent any disease. The health research on grounding is genuinely interesting in places and thinner than this industry usually implies. We publish the full picture — the weak studies alongside the strong ones — so you can weigh it yourself.

Materials and construction
90% organic long-staple cotton, 10% pure silver fibre woven through the fabric — not a silver-bearing coating sprayed onto the surface. Coatings are what most sheets under $100 use, and they start shedding in patches after five or six washes. A woven fibre cannot flake off, because it is the fabric.
It feels like a good percale sheet. The silver threads are visible if you look closely and completely unnoticeable when you're asleep.
Care and washing
Wash it in the sheet-care bag. Cold water, gentle cycle, no bleach, and no fabric softener — softener leaves a residue on the fibres that raises resistance at the skin contact point, and it washes back out.
Line dry or tumble low. Every 2–3 weeks is fine. Every wash costs a little conductivity.
Care and use
1. Set it up. Clip the cord to the snap on the sheet and plug the other end into an outlet with a working ground. If you're unsure about an outlet, try another one, or ask a licensed electrician to check and correct its ground.
2. Sleep on it every night. Bare skin on the sheet.
3. Care for it. Wash it in the sheet-care bag. No bleach, no fabric softener.
Shipping, guarantee and returns
We ship to the United States and Canada, and shipping is free on every order.
Dispatch: within 1–3 business days of your order — allow up to 5 during peak periods such as Black Friday and the December holidays.
Delivery after dispatch: about 8 days on average to the US, and about 9 days to Canada.
All in, allow roughly two weeks from order to doorstep. You'll get a tracking number by email when your order ships.
Prices are in US dollars. Canadian orders may be charged import duty and GST/HST by the carrier on delivery; these aren't included in our price.
90-night money-back guarantee. Sleep on it for the full 90 nights, counted from delivery. If it isn't for you, send it back and we'll refund the full price of your items. You don't have to tell us why, though we'd be grateful to hear how it went.
How it works: between night 90 and night 100, email support@restoreearth.store with your order number and a photo of the items with their original packaging. We'll reply with the return address. Send the items back clean, undamaged and in their original packaging within 14 days of our reply. Return postage is paid by you. Once your return reaches us, we refund the full price of the items to your original payment method.
We can't take refund requests for used items before night 90, because many people notice nothing for the first two or three weeks. Please keep the box and packaging until your 90 nights are up.
Changed your mind before sleeping on it? Within 14 days of delivery, you can send back unused items in their original packaging for a full refund, or swap a sheet for another size. Return postage is paid by you; we ship the new size free.
Damaged, faulty or the wrong item? Email us a photo or short video within 7 days of delivery, or within 7 days of noticing a manufacturing fault during your 90 nights, and we'll send a replacement free.
Safety, and who should ask a doctor first
The cord connects to your outlet's ground port only. There is no current running from the outlet into the sheet — it is a path to earth, not a power source, and an inline resistor sits between you and it as a second safeguard. Plug the cord into an outlet with a working ground. If you're unsure about an outlet, try another one, or ask a licensed electrician to check and correct its ground.
Speak to your doctor first if you have an implanted device such as a pacemaker, take anticoagulant medication, or are managing a condition under medical supervision. Grounding is not a treatment and should not replace anything a physician has prescribed.
Which size do I need?
Match your mattress, not your duvet. If you're between sizes, go up — a loose fitted sheet still conducts, a tight one pops off.
| Size | Mattress (in) | Mattress (cm) |
|---|---|---|
| Single / Twin | 39 × 75 | 99 × 190 |
| Double / Full | 54 × 75 | 137 × 191 |
| Queen | 60 × 80 | 152 × 203 |
| King | 76 × 80 | 193 × 203 |
| California King | 72 × 84 | 183 × 213 |
All sizes fit mattresses up to 13 in / 33 cm deep.
Anatomy
Four decisions that matter.
Woven, not sprayed
Most sheets under $100 use a silver-bearing coating applied to the surface. It sheds in patches, and the sheet looks identical while it happens. Ours is fibre woven through the cloth — it cannot flake off, because it is the cloth.
10% silver, evenly through
Twice the silver content of a typical grounding sheet, distributed across the whole sleeping surface rather than concentrated near the stud. Conductivity is even wherever your skin actually lands.
Deep corners, one stud
Elasticated to 13 inches so it holds a mattress with a topper on it. A single low-profile snap at the foot corner — the cord runs down the side and out of sight.
Gifts, included
A silk sleep mask and sheet-care bags come with every kit, along with the Grounded e-book.

Straight answers
Before you buy
Does this actually do anything, or is it wellness nonsense?
The electrical effect is real and measurable — grounded, your body voltage drops to near zero, and you can verify it with a meter. The health effects that get claimed online run well ahead of the evidence. We'd rather you buy this understanding exactly that.
Will I feel something the first night?
Some people report falling asleep faster within a few nights. Many notice nothing for two or three weeks. A few notice nothing at all — which is why the trial is 90 nights and not 30.
How do I know it's working?
Grounding is a wellness practice, not a medical treatment, and results vary. We suggest sleeping grounded every night for the full 90 nights, which is why the guarantee runs that long. If anything arrives damaged or the cord won't connect, email support@restoreearth.store within 7 days of delivery and we replace it. Care and use guide.
Is it safe?
Yes. The cord connects to your outlet's ground port only — there is no current from the outlet running into the sheet. It's a path to earth, not a power source. Plug the cord into an outlet with a working ground. If you're unsure about an outlet, try another one, or ask a licensed electrician to check and correct its ground.
What if my outlet isn't grounded?
Plug the cord into an outlet with a working ground. If you're unsure about an outlet, try another one, or ask a licensed electrician to check and correct its ground.
Does it feel like a normal sheet?
90% organic cotton, 10% silver fibre. It feels like a good percale sheet. The silver threads are visible if you look closely and completely unnoticeable when you're sleeping.
How do I wash it?
Wash it in the sheet-care bag. Cold water, gentle cycle, no bleach, no fabric softener — softener coats the fibres and reduces conductivity. Line dry or tumble low. Washing every 2–3 weeks is fine. Every wash costs a little conductivity.
Do I need the pillowcases and mat too?
No. The sheet does most of the work because it's the largest area of skin contact for the longest time. The pillowcase adds head and neck contact; the mat is for daytime use at a desk. Start with the sheet.
