Our Most Trusted Sleep Tools
Every product is designed around the research and refined until it earns its place on your bed. Simple tools, built properly, so your nights do the work.
Most Bedrooms Keep You Wired, Even While You Sleep
Phones, chargers and live wiring raise the charge your body carries indoors. That can keep your nervous system slightly activated all night.
For most of history, contact with the earth kept that charge at zero. Modern life broke the contact.
The Science of Better Sleep
Your body runs on tiny electrical charges. Modern life broke the contact with the ground. A Cadian sheet quietly restores it while you sleep.
The wiring in your walls is live all night, and every plugged-in device adds to the ambient electrical field around your bed. Your body picks up that field as a small measurable voltage. It carries no current and cannot shock you, but it can keep your nervous system slightly more activated than it would be outdoors, where your body voltage sits at zero.
The sheet is woven with 30% medical-grade stainless steel and connects to the earth pin of your wall socket. The moment your skin touches it, your measured body voltage drops to near zero, the same state as standing barefoot on grass. Research suggests that sleeping in this state may support sleep quality, deeper recovery and a calmer nervous system.
The sheet lies under your normal fitted sheet, so nothing about your bed changes. It works for one sleeper or two, fits Double, Queen and King, and is machine washable without losing conductivity. The mat covers desks, sofas and travel. Setup takes under 2 minutes.
Yes. The cord connects only to the earth pin, the safety pin that already grounds your appliances. No electrical current flows through it, and it draws zero power. A socket tester is available separately so you can confirm your socket is safely earthed before your first night.
What The Experts Say About Grounding
“After a few trips, I confirmed for myself that grounding worked for reasons I didn't understand.”

“If we are sleeping for 8 or 9 hours in a bed, we might as well make them hours where our body is electrically docked into the earth.”

What Deeper Rest Actually Feels Like
Faster Recovery
Grounding may support faster muscle recovery, so you wake up feeling rebuilt.
Increased Energy
Deeper sleep promotes steadier, more even energy across your day.
Mental Clarity
A calmer nervous system supports sharper focus and clearer thinking.
Decreased Inflammation
Free electrons from the earth may help support a lower inflammatory response.

Frequently Asked Questions
Fair question. Grounding has more than 20 peer-reviewed studies behind it, including double-blind trials, and the core effect is measurable. Touch the sheet with a multimeter on your skin and you watch your body voltage drop to near zero. We hedge every other claim, because that is what honest science sounds like.
Placebo cannot move a multimeter. The voltage drop is physics and happens whether you believe in it or not. The sleep and recovery findings come from studies where participants did not know if their sheet was actually grounded, which is exactly the design that rules placebo out.
Most cheap sheets rely on a silver coating that washes out within months, and then you are sleeping on an ordinary sheet that cost you $50. Cadian weaves 30% medical-grade stainless steel through the fabric itself, tested to stay conductive wash after wash. Over a year it works out to about $0.87 a night.
There is no routine. You fit the sheet under your normal fitted sheet once, plug the cord into the earth pin, and then you just sleep like you always do. No change to your routine. No effort required.
Research suggests most people notice calmer nights within 2 to 4 weeks, some sooner, and individual results vary. That is exactly why every sheet comes with a 100-night trial. Sleep on it for three months, and if your nights are no better, return it in good condition for a full refund. Customer pays return shipping.
