Returns, in full
Returns, in full
90 nights, counted from the day it arrives rather than the day you ordered.
- Email us first. A person replies within 1 business day, with a name at the bottom.
- Refunds open from night 30. A sheet you slept on twice hasn’t been tried, and we’d rather you gave it a month than a weekend.
- Send the sheet back. Pay the postage at the counter and photograph the receipt. We refund what you paid for the sheet and the exact postage on that receipt, so the return costs you the trip and nothing else. The one exception is an outlet that was never grounded: once a photo of an outlet tester confirms it, and no other outlet within reach of the cord is grounded, the refund starts right away, without the 30-night wait. The postage back is yours.
- Everything that came free is yours. The tester, the mat and the guide stay with you, whatever you decide.
- 1 refund per customer, household or payment method.
We refund sheets that have been slept on, and we don’t ask how you washed it or whether you kept the packaging. Read the full policy.
Care
Care
Wash cold every couple of months. Line dry. No bleach, no fabric softener, no dryer. Those 3 are what shorten the life of a conductive sheet, and we’d rather print it than have you find out.
No grounded outlet? Go straight to the source.
This outdoor grounding rod kit connects your grounding mat or sheet directly to the earth, with no wall outlet involved. A simple option for older homes with two-prong outlets, rentals, cabins, or anyone who prefers not to plug into the wall.
Why you'll like it
- No outlet needed – a direct connection to the ground outside your home.
- 40 ft of reach – enough cord to run from the yard, through a window or door, to your bed, couch or desk.
- Plug-and-snap setup – no tools, no wiring, ready in minutes.
- Lightweight and portable – pull it up and take it with you when you travel or move.
- Made for snap-port grounding products – connects to grounding mats, sheets and throws with a snap-button port.
What's in the box
- 1 × grounding rod with attached 40 ft cord
- 1 × connector cord (plug on one end, snap on the other)
Set up in 3 steps
- Push the rod into moist soil outside, close to a window or door. If the ground is dry, water the spot first.
- Run the 40 ft cord indoors through a window or door gap. Keep it out of walkways.
- Plug the connector cord into the end of the rod cord, then snap it onto your grounding mat or sheet.
Good to know
- Never connect any part of this kit to an electrical outlet or power source.
- Disconnect the cord during thunderstorms.
- Do not place the rod near buried utility, gas, irrigation or septic lines.
- For grounding mats and sheets only. Not for grounding electrical systems or appliances.
- Not a toy. Keep out of reach of children and pets.
- Store in a dry place away from heat and direct sunlight when not in use.
FAQ
Do I need this if my outlet is grounded?
Not necessarily. If your outlet passes a ground test, a standard outlet cord works. This kit is for when you can't, or would rather not, use the outlet. Not sure? Test your outlet first.
Will it work in an apartment?
Only if you can reach soil within the 40 ft cord length, for example from a ground-floor unit, patio or garden.
Can I leave the rod in the ground?
Yes. Just disconnect the cord indoors during thunderstorms.

IF YOU KNOW THIS HOUR, THIS PAGE IS FOR YOU
3:32 AM
You’re awake, and you’ve already done the math on how many hours you have left.
You fell asleep fine. That was never the problem. The problem is that you’re up again, the room’s the same room, and the arithmetic starts on its own. 3 hours and 28 minutes if you fall asleep right now.
Sometimes it’s the heat: covers off, covers back on. Sometimes it’s nothing at all. The waking takes a minute. Getting back is the part that takes the night. And it’s the same hour as last night, whatever time you went to bed. That’s not a habit. That’s a clock.
In the morning you’ll run on coffee. Tonight you’ll run on whatever’s in the drawer. You know the loop isn’t sustainable. You’ve known that for a while.
Most people reading this got here the same way: something worked, then it worked less, then the dose went up.
I WANT TO STOP FEELING EXHAUSTED ALL DAY
The part that happens after you get up.
The reason any of this matters isn’t the night. It’s the 14 hours after it.
Coffee because you like it, not because you can’t function without it. A morning meeting you don’t push to the afternoon because you don’t trust your head before noon. Not snapping at your kid over nothing, then apologizing, then doing it again tomorrow.
That is the thing being bought. Nobody buys a bedsheet.
That’s the version of the problem worth solving, and a stronger dose was never going to solve it. 90 nights is how you find out what this does to your mornings.
THE PART NOBODY POINTS OUT
Everything you’ve already tried has the same shape.
Melatonin. Magnesium. Gummy. Tea. The prescription. Wine.
Every single one of them goes in you. And whatever goes in you at 10pm is still in you at 7am.
That’s the fog. The first hour where you read the same email 3 times. The word that won’t come in the meeting. Walking into the kitchen and standing there, trying to remember why. You slept, technically. You just woke up underneath something.
Groggy is the polite word for it. Some mornings it’s closer to stupefied, and coffee only gets you partway back.
And somewhere in there you read the headline about sleeping pills and dementia. Now 3:32 has something new to think about.
That is not a melatonin problem. That is a swallowing problem.
Whatever you swallow to get to sleep, you wake up with. A gentler one just means a thinner fog.
Your HRT is a different thing, and it stays. Nothing here asks you to drop what your doctor has you on. This goes under you, not into you.
The other half of the list doesn’t go in you. The breathing. The app. The trick from CBT. The wind-down routine. The rules about screens and caffeine and bedtime. Every one of them needs you awake to work it.
Both halves were built for 10 p.m. One leaves you the fog at 7. The other stops the moment you fall asleep. Neither one is working for you when the clock turns at 2 or 3.
So stop looking for a better one, and look at the other category instead. The one that doesn’t go in you at all, and doesn’t need you awake to work.
THE OTHER CATEGORY
There is a wire running into the ground under your house.
It’s been there since the day the building went up. Every outlet in your home has a hole for it. The round one at the bottom. The one you’ve never used for anything.
It doesn’t carry power. It’s the safety wire, a straight path into the earth, and the electrical code requires it in every new home in America for exactly that reason.
The sheet goes on your bed, you sleep on it, and it connects to that wire while you do. That’s the whole mechanism. There’s no battery, no field, no frequency, and nothing to switch on.
We named the company after that hole. It seemed like the honest thing to point at.
WHAT ACTUALLY MOVES
It starts in your body, not your head. And your calm side rides on the sleep you just lost.
Hormones, a call from down the hall, a pill wearing off: whatever starts it, at 3 a.m. you feel it in your body before your mind catches up: heart going, wide awake. That’s the alert side of your nervous system up, and the calm side, the brake on that alarm, down.
Here’s the catch. Your calm side rides on sleep. It rises as you drift off and it’s highest in deep sleep. Wake up, and it loses the thing that was lifting it. The only lever left is effort: breathing, counting, the app, done by you, awake, at the worst hour of the night.
The sheet lifts it without you. Skin on the cotton, the cord in the ground port, and you’re connected from lights-out to the alarm, 3 a.m. included. Up for the bathroom? It’s under you again the second you lie back down, right where getting back to sleep starts. Nothing to do, nothing to remember.
In a sham-controlled test, healthy people sat resting in a recliner for 40 minutes, grounded, and a calm-side heart marker rose 63%, against 33% on a fake connection (Chevalier and Sinatra, Integrative Medicine, 2011). It was still climbing when the 40 minutes ended.
At 3 a.m. you’re lying there too, only wide awake. And by then you’ve been connected for hours, not 40 minutes. That’s the hour we built this for.
You don’t have to take the connection on faith. Put a meter on your skin with the cord out, then with it in, and watch the reading fall toward zero. That’s the connection, on a screen, the night the sheet arrives.
Think of the sheet as an extension cord to the Earth. It doesn’t generate anything, emit anything, or run on anything. It connects you to the ground you’re standing on anyway.
I WANT TO STOP NEEDING A PILL TO GET THROUGH THE NIGHT
There is no dose in this.
You don’t take it. You don’t time it an hour before bed, or set an alarm for midnight to take the second half. You don’t raise it in 6 months because it stopped doing what it did in month 1.
A sheet is not a dose. There’s nothing to adjust to.
There’s nothing in it for your body to get used to. That’s what takes the drawer out of your evening. It’s connected or it isn’t, and on night 60 you check it the same way you did on night 1.
I WANT TO SLEEP THROUGH THE WHOLE NIGHT
You do not want better sleep. You want the whole night.
Not 8 hours of lying there. One stretch. You go down, and the next thing you know the alarm’s going off and it’s already light outside.
No 3:32. No arithmetic. No lying there deciding whether to get up or keep trying.
$97. Once.

$12 a month
A bottle you rebuy, at a dose that’s been climbing for 4 years. Call it $144 a year. There’s always a year 2.

$97, once. One size. There’s no year 2, and nothing renews.
-
$2,000+
The mattress systems. $2,000, and the wire at the end of it goes to the same place ours does.
1 year of the drawer costs more than the sheet does, and the sheet doesn’t renew. Check it against your own receipts.
Against everything else in the drawer.

Setup takes about as long as making the bed.
-
1. Check the outlet beside your bed
It needs a real ground. In older houses plenty of 3-prong outlets were retrofitted without one, and that’s one of the most common reasons a grounding sheet does nothing. The outlet tester in your box answers it in 4 seconds.
-
2. Lay the sheet down
On top of your fitted sheet, and you sleep straight on it. Skin against the silver is how it was tested, and it’s cotton, not a plastic mat, so there’s nothing to get used to.
-
3. Plug in the cord
Snap the flat end onto the stud, put the other end in the round hole at the bottom of the outlet.
-
4. Sleep
No pill an hour before. No wind-down routine. Just go to bed.
Who you are actually buying from
This is a small company. Small enough that when you write in, it reaches the person who chose the fabric.
We read several thousand reviews of grounding sheets before we built anything. The 1-star reviews almost never said the sheet was bad. They said nobody answered.
So that’s the company. The sheet is good. The answering is the point.

FAQ
The questions people actually ask
A bedsheet is going to do what melatonin couldn’t?
Different question than the one you’re asking. Melatonin gave you a dose, and your body did what bodies do with doses. This doesn’t give you one. It connects you to the ground wire under your house while you’re already lying still the whole night. You’ve got 90 nights to find out what that does. What it won’t do is stop working in month 6 because you got used to it.
I’m on HRT. Can I use this alongside it?
Yes. Nothing goes into your body, so there’s nothing to mix with what you take. Keep everything your doctor has you on, and put the sheet under you.
This sounds like a wellness thing. Is there any actual evidence?
Yes. Start with the half you can check yourself: put a meter on your skin, plug the cord in, and the reading falls toward zero in under a minute.
Then the body. In a sham-controlled test, healthy people sat resting in a recliner for 40 minutes, grounded, and a calm-side heart marker rose 63%, against 33% on a fake connection (Chevalier and Sinatra, Integrative Medicine, 2011). Same people, same setup, same 40 minutes; the only difference was whether the wire reached the ground. That’s the test that separates a real effect from plain rest. There’s also a study on a sheet like this one: 10 nights, triple-blind, run by university researchers with no declared commercial ties (Müller and colleagues, Frontiers in Physiology, 2019). That one measured muscle recovery, not sleep.
The sleep part you test on your own nights. That’s what the 90 are for.
How do I know it's actually working?
Start with the outlet, because an outlet without a real ground is one of the most common reasons a grounding sheet does nothing. Plug in the free tester and its 3 lights tell you in 4 seconds. Grounded outlet, cord in, skin on the sheet: you're connected. After that, the proof is your nights, and that's what the 90 are for.
How long until I know? I don’t want to sleep on this for 3 months and find out it’s nothing.
Give it 30 nights, not 3. Some people notice something in the first few nights. For others the first week is nothing, and a night or two can even feel worse while you settle in.
That’s why refunds open on night 30, and the 90 nights start the day it arrives. You judge it on a month of your own nights, and if it isn’t for you, the sheet and the return postage both come back.
Can't I just walk barefoot on the grass?
You can, and it's the same connection. The difference is when. Twenty minutes on the lawn happens in daylight. 3 a.m. happens in bed, and that's where the sheet is: connected the whole night while you sleep, with nothing to remember.
Do I have to sleep naked on it?
No. You need some skin on it, not all of it. An arm, your feet, a shoulder, that’s contact. Put it on top of your fitted sheet and sleep the way you already sleep. It’s cotton with silver woven through it, not a plastic mat you have to negotiate with, and bare skin against the fabric is how the sheet in the 2019 trial was used.
I already sleep hot. Won’t another sheet make it worse?
It’s cotton, one layer on top of your fitted sheet, not a plastic-backed mat. And if the covers come off at 3, it’s still under you.
$97 for a sheet. My whole mattress cost $600.
Fair. Here’s the arithmetic. A bottle at $12 a month is $144 a year, and the dose has been climbing for 4 years. This is $97 once, and there’s no year 2. You’ve already spent more than this on the thing that stopped working.
Is this a subscription?
No. You pay once, $97 for one sheet or $163 for two, and that's the only charge. Nothing renews, nothing ships again unless you order it, and the free gifts don't sign you up for anything.
How long does delivery take?
Processing takes 1 to 3 business days. Delivery is 7 to 10 business days in the United States and 7 to 14 internationally. You get a tracking number by email the moment it leaves, and if anything goes wrong on the way, write to Support@thegroundport.com and we'll chase it with you.
What exactly is the refund policy?
90 nights from the day it arrives. Refunds open from night 30, because a sheet you slept on twice hasn't really been tried.
Email us first and a person replies within 1 business day. Send the sheet back and photograph the postage receipt: we refund what you paid for the sheet plus that postage, even if you've slept on it. 1 refund per customer, household or payment method. If your outlet has no real ground and none within reach of the cord does either, we refund right away, without the 30-night wait, and the postage back is yours.
Whatever you decide, the free tester, mat and guide are yours. The rest is in the full policy.
Is it safe to plug this into my wall?
Yes, and the reason’s worth understanding. The cord only ever touches the ground port, the round hole at the bottom of the outlet, which carries no electricity. It’s the safety wire, the path the electrical code requires in every new American home precisely because it’s the safe way to earth. The cord also has a resistor built in, which limits current regardless of what happens upstream.
Is the free tester one of those pens that light up on everything?
No. A non-contact voltage pen reacts to nearby metal and static charge, which is why it glows over an unplugged sheet in the videos going around. It isn't a grounding test. That's exactly why we don't ship one. Every box gets a real plug-in outlet tester instead: 3 lights that read the actual wiring behind the wall. Test the sheet itself with a multimeter. If a company hands you a tool that lights up no matter what, that tool is decoration.
I heard silver sheets stop working after a few washes. Does this one?
Some do. It comes down to when the silver goes on. Coat a finished fabric and the wash starts scrubbing it off from the first cycle. Ours goes on the thread before the thread is woven, so the silver sits inside the weave, where the drum has far less to grab. Wash it cold every couple of months, line dry, skip the softener.
Check it any time: multimeter on continuity, both probes on the fabric. Not through the cord. The safety resistor in it keeps a meter silent, on our cord and everyone else’s.
Wake up without doing the arithmetic.
Not a stronger dose. A different category. 90 nights start the day it arrives, not the day you make up your mind. Give it 30 before you decide, and if it isn't for you, the sheet and the return postage both come back.
