The sheet
What is a grounding sheet?−
A flat cotton sheet woven with 30% stainless steel fibre. Two elastic straps run the length of the mattress, head to foot, one on each side. It sits under your own fitted sheet and connects by a cord to the earth pin of a wall outlet. Same electrical contact as standing barefoot on grass, overnight.
How do I set it up?+
Lay it flat above your mattress protector. Run the two elastic straps the length of the mattress, one on each side, from head to foot. Snap the grounding cord to the sheet, plug the cord into the earth pin of a standard earthed wall outlet, then put your own fitted sheet over the top and sleep as normal.
Will it work with my mattress, topper and doona?+
Yes. The grounding sheet sits above a mattress protector and under your fitted sheet. A topper sits under it if you use one. The doona goes on top of you. Works with any standard mattress: memory foam, hybrid, latex or innerspring.
Do I need bare skin on the sheet?+
No. You sleep on your own fitted sheet. The connection works through a cotton fitted sheet, so bare skin on the grounding sheet is not required. Thick synthetic layers between you and the sheet will reduce it.
What sizes and colours are available?+
Two sizes, Double/Queen (153 × 190 cm) and King (193 × 203 cm), in two colours, Midnight and Stone. Stone straps are white. Midnight straps are black.
How do I wash it?+
Wash every one to three months on a cold, gentle cycle. No bleach, no fabric softener and no dryer sheets, because those coat the conductive fibre. Line dry only, never tumble dry.
How long does it last?+
It's built to keep working for 10 years, and it's backed by a three-year warranty.
Does it actually work?
What does the research actually show?+
Grounding is scientifically proven in published human studies and electrical measurements. The strongest sleep result is a 2025 randomised, double-blind, placebo-controlled study that reported longer actigraph-measured sleep time versus sham after 30 days. Other studies have measured faster sleep onset, fewer night wakings, faster recovery, less pain and a calmer stress response, and you can read every one on our science page.
How long until I feel a difference?+
Many people notice calmer nights within the first few weeks, and for others it builds over a month or more. Studies have measured effects from within minutes to 30 days. That is why you get 100 nights to decide.
Will I see it on my Oura or Whoop?+
Some customers track their sleep and recovery on a wearable and watch their own data over the trial. Wearable trackers may show measurable change, but results vary from person to person, we can't promise a specific number.
Is it safe?
Is it safe to plug into the wall?+
It is designed to connect only to the earth pin and includes a safety resistor in the cord. Use only with a correctly grounded outlet and verify the outlet before use.
Is this a medical device?+
No. Cadian is a textile product, not a medical treatment. It isn't intended to diagnose, treat, cure or prevent any condition, and it's not a substitute for medical care.
I have a health condition, should I check first?+
If you have a medical condition or any concern, speak with your doctor before making changes to your routine. Cadian is a supportive product, not medical advice.
Can I use grounding bed sheets if I have a pacemaker or ICD?+
You should consult your cardiologist before using grounding bed sheets if you have a pacemaker or implantable cardioverter-defibrillator (ICD), as specific interactions have not been clinically studied.

What our sheet customers say
I used to need 2 coffees just to function. Now I wake up actually feeling like I slept. Joint aches are milder too. Took about 3 weeks to really notice.
Love that it uses stainless steel instead of silver that oxidises. Comfortable under my regular sheets. Sleep has improved and my chronic shoulder pain is better after a month.
Chronic lower back pain from an old injury. After consistent use for 5 weeks the pain is more manageable and sleep is better. Grateful for this product.
First week nothing. Second week subtle. By week 4 I could tell the diference in how I felt getting out of bed. Less achy, more energy. Stick with it.
Was on the fence because of the price but the trial period sold me. Results after a month: better sleep quality, less joint pain. Will keep using it.
Works as advertised. Deeper sleep, fewer night wakings. The 100 night trial gave me confidence to try it. Glad I did. Easy to put under the fitted sheet.
We both sleep on it. My partner's sciatica is less bothersome in the mornings and I'm sleeping deeper. Win win. Easy to install under the top sheet.
Bought it on a whim during the sale. Didn't expect much. By week 2 I was falling asleep faster and not tossing as much. Wife noticed I was less grumpy in the mornings lol.
Friend swore by grounding so I tried Cadian. Results after 3 weeks match what she said - better rest, less joint discomfort. Good stuff.
Noticed I was waking up less foggy after about 10 days. My Oura ring shows a bit more deep sleep too. Sheet is soft and goes under my normal sheets no problem. Setup was easy.
Tried a couple cheaper ones before that stoped working after washes. This one feels premium and the stainless steel should last. Sleep quality improved within the first fortnight. Feeling more rested.
Doesn't change the feel of the bed much. Benefits showed up gradually. Sleep longer stretches now. Would recommend to others with similar issues.
I used to thrash around half the night. Now I wake up in the same position most mornings. Sleep feels restorative. Sheet is comfortable.
Not sure if related but my night sweats seem less intense. Main win is solid sleep and less stiff when I get up. Sheet quality is excellent.
Not a miracle cure but a solid improvement in sleep continuity and morning feel. Easy setup, good instructions. Happy I tried it during the promo.
Sheet arrived quickly, everything included. Results kicked in around week 3. Less inflammation in my knees, better sleep. Satisfied.
If you struggle with light sleep or frequent wakeups this is worth trying. My sleep efficiency improved and I feel more recovered. Quality product.
My Whoop shows improved recovery and HRV since starting. Subjectively I feel more rested. The sheet itself is well made and stays in place with the straps.
Had a budget grounding sheet that lost conductivity fast. This one feels different - denser weave. Sleep benefits are clear after a few weeks. Good investment.
