Your home's electrical system is connected to the earth — that's what the round hole in your outlet is for, and it's a safety feature every building has.

The cover's conductive surface connects to that same earth through the cord. Lie on it and you're connected to the ground beneath your house, much as you would be standing barefoot outside.

Fair question — this category has earned the skepticism. The honest answer: the grounding connection itself is real physics you can measure. The test pen included with your cover checks that it's actually conducting — not a promise from us, something you verify yourself on night one. 

Whether you feel a difference is something only you can judge, which is why you get 90 nights to decide, and your money back if you don't.

Yes — it's safe by design. The cord connects only to your outlet's ground, never to live current, so there's no path for live current to reach you.

The plug has a single round pin, sized for the ground port of a standard US grounded outlet — it physically can't fit the flat live slots. And a 100 kΩ safety resistor is built into the cord as a second safeguard. You're connecting to the same protective earth connection your home's wiring is built around, not to its live power.

No — nothing extra is needed. The cord plugs straight into the round ground port of any grounded US outlet on its own.

The Dual-Port Adapter is there for one specific situation: grounding two products from a single bedside outlet — your cover and a grounding pillowcase, for example. One plug, one socket, both grounded, instead of two adapters competing for space beside your lamp.

Most homes built after 1970 have grounded outlets — the kind with three holes, including a round port at the bottom. If you're not sure, an inexpensive outlet tester from any hardware store confirms it in seconds, or contact us and we'll walk you through checking.

If your outlet isn't grounded, get in touch — we'll help you figure out your options.

Yes, on any floor. The grounding port in your outlet connects to your building's earth whether you're on the ground floor or the twentieth — the wiring does the work, not your height. 

What matters is that the outlet is grounded, which an inexpensive outlet tester confirms in seconds.

A wall outlet is the more reliable choice. Many power strips pass the ground through correctly, but not all do, and a cheap one can look fine while the ground path isn't there. If you'd rather use a strip, check it with an outlet tester first.

No. There's no power running through it — no electronics, no battery, no current. It's a passive connection to your home's earth, the same one every appliance already uses.

Some people notice a difference in the first few nights. Others take longer, and some don't feel much at all — that's the honest answer, and it's why we give you 90 nights rather than asking you to take our word for it. A few people report a mild tingling early on that settles.

Grounding isn't a stimulant or a sedative. It's contact with the earth's electrical field, the way your body would experience it outdoors.

If you have a pacemaker, take blood-thinning medication, or are pregnant or nursing, please talk to your physician before use.

The conductive side faces up, toward you — that's the smooth, leather-look surface. The other side is the backing.

Not sure which is which? Touch the test pen to each face with the cord plugged in. The conductive side is the one that reads.

The cover lays flat on top of your mattress, held in place with adjustable straps so it won't shift overnight. You then make the bed as usual, with one thin natural-fibre fitted sheet over the top. You sleep on the sheet — grounding still passes through a thin natural-fibre layer, with direct skin contact giving the strongest connection.

Either works. We suggest keeping a thin fitted sheet over the cover — your sheet takes the washing, so the cover itself rarely needs it. Grounding still passes through thin natural fibre like cotton or linen.

If you prefer the strongest connection, bare skin directly on the cover works too — a quick wipe-down keeps it fresh, with an occasional gentle machine wash when it needs one.

Keep any layer thin: thick mattress toppers and synthetic sheets can block the connection.

The sheet over the cover works best as a natural fibre — cotton or linen — because grounding passes readily through natural fibres and poorly through polyester and synthetic blends. Keep it to one thin layer between you and the cover. 

Most people already have a cotton sheet in the linen closet, or a basic one runs $30–50 online.

No. It's a thin layer that sits under your fitted sheet, and the surface is perforated so air and moisture pass through it rather than being trapped. It's designed to disappear into the bed you already have.

It comes in two sizes: Half Bed (28" × 71") covers one sleeper's side, and Whole Bed (53" × 80") fits Full, Queen and King beds. Adjustable straps hold it in place under your fitted sheet.

Not sure which fits your bed? The size guide on the product page walks you through it.

It needs very little cleaning. Because your fitted sheet sits between you and the cover, it mostly stays clean on its own — a wipe with a damp cloth handles the rest. When it does need a wash: machine wash cold on gentle, air dry in the shade away from direct sun and heat, no bleach.

Our conductive layer is carbon-infused PU leather — the carbon is built into the material itself, not applied to the surface.

You don't have to take that on trust. The test pen included with your cover lets you check conductivity whenever you like — night one, and any night after. And we back it with a 3-Year Conductivity Guarantee: if it fails a conductivity test within 3 years of delivery, we'll replace it free.

Sleep on it for 90 nights. If it's not for you, send it back for a full refund — used and washed is fine. We'll never deny a refund because you slept on it. 

See our full refund policy for details.

Orders are dispatched within 3–5 business days and typically arrive 5–12 days after that, with complimentary tracked delivery. Your tracking number arrives by email when your order ships — allow 1–2 business days for it to start updating.

Your 90 nights begin the day your cover arrives.

Probably not. It's normal for tracking to stay quiet for the first several days after dispatch. If nothing has moved after 10 days, email us and we'll chase the carrier.
