3-Year Warranty

The short version. Three years from the day it arrives. In the first year, if the sheet stops grounding, we send you a new one. For all three years, if something in how it was made gives way, we send you a new one. You do not need a meter, you do not post anything back, and we do not ask how you washed it.

The rest of this page is the detail, written out so that none of it is a surprise later.


The first year

Your first year starts the day the sheet arrives, the same day your ninety nights start.

If the sheet stops grounding in that year, we send you a new sheet and a new cord. Silver thread wears with washing and with use, on every sheet that has it, and some sheets wear faster than others. In the first year, that is our problem, not yours.

We do not ask how you washed it, how hot, or whether it met a tumble dryer. We have no way to check, and a promise that depends on something nobody can check is not much of a promise.

Everything in the list under years two and three is covered in the first year too.

Years two and three

From the second year, the warranty covers how the sheet was made:

  • The stud on the corner comes away from the fabric, or stops holding the cord.
  • A seam or hem comes undone along its stitching.
  • The cord stops working.

If one of those happens, we send you a new sheet and a new cord.

What it no longer covers is the silver wearing thin. We would rather tell you that here than in an email two years from now. The care notes at the bottom of this page are how to make it last.

What is not a fault

  • The silver darkening. Silver darkens as it meets air and skin. Colour is not what we test. Grounding is.
  • Pilling, fading and softening. They are what cotton does.
  • Damage from outside the sheet: cuts, burns, scorch marks, chewing, and tears from catching on something.
  • An outlet that is not grounded. That is the wiring in your wall, not the sheet. In your first ninety nights it has its own lane on our Refund Policy page, and after that we will still help you find an outlet that works.
  • From the second year, the silver wearing thin.

How to claim

  1. Email Support@thegroundport.com with your order number. A person replies within one business day.
  2. Tell us what happened and send one photo.
    • If it stopped grounding: the outlet tester from your box, plugged into the outlet by your bed, with its lights showing. That tells us the problem is not in the wall, so we do not send you a new sheet that would do the same thing.
    • If something gave way: a photo of it.
  3. Once we reply, we send you a code that is only for this claim. Write it on a piece of paper and film yourself cutting off the corner of the old sheet that holds the stud, with the paper in the frame. One take, about ten seconds. If the stud has already come off, cut off the corner where it was. Please do not cut anything until we have replied.
  4. We order your new sheet and cord within one business day of that video. There is nothing to pay, wherever we ship.

Why we ask you to cut off the corner

A sheet without its stud cannot be plugged in, and a corner can only be cut off once. It is the one thing we ask, and it is what lets us skip the meter, the return postage and the questions. The old sheet is yours to keep as an ordinary sheet, or to throw away.

The rules that keep this possible

Up to two new sheets for every sheet. Each sheet you buy can be replaced up to two times in its three years. If you bought two sheets, each one has its own two.

A replacement takes over the time left. It does not restart the first year, the three years, or the ninety nights.

Each code works once. We send a new one for every claim, so a video only ever counts for the claim it was made for.

Your claim is dated the day you first email us. If your first year or your third runs out while we are sorting it out, that does not count against you.

Bought from this website. The order number is how we find your sheet. If the sheet was a gift, the order number is all we need, from whoever is sleeping on it.

A new sheet, not a discount. We do not offer a coupon in place of a sheet. If we no longer make yours, we send the closest one we make. If nothing we make is close, we refund what you paid for that sheet.

Inside your ninety nights you can still choose a refund. It runs on the terms of our Refund Policy. If the sheet has already been replaced, send back the new one. The old one, without its corner, stays with you.

If it arrived damaged or faulty, our Refund Policy covers that in the first thirty days, and there you choose: a replacement or your money back.

The free mat and outlet tester are covered if they arrive damaged or faulty, under that same part of the Refund Policy. This warranty covers the sheet and its cord.

Looking after it

None of this is a condition of the warranty. It is how to need it less.

Wash it cold, every couple of months. Line dry. No bleach, no fabric softener, no dryer. Those three are what shorten the life of any conductive sheet, whichever brand you buy.
