How do our premium grounding underlays work?
The Difference Is in the Design
Built to Outperform. Made to Last.
Most grounding sheets wear out because they take the full hit — body friction, sweat, skin oils and constant washing. Our Premium Grounding Underlay is designed differently.
It sits protected beneath your normal fitted sheet, helping reduce wear and preserve strong conductivity for years of everyday use.
✓
Protected Under Your Sheet
Less direct friction. Less sweat exposure. Less frequent washing. That means better long-term performance compared with direct-contact grounding sheets.
✓
Medical-Grade 316 Stainless Steel Conductive Fibre
After 9+ years in grounding products, we use medical-grade 316 stainless steel conductive fibre for strength, durability and corrosion resistance.
✓
The Right Conductive Blend
In our testing, under 30% conductive fibre didn't perform strongly enough beneath a normal sheet, while higher blends affected comfort. Our 30% blend gives the sweet spot: conductivity, comfort and durability.
This isn't a cheap throwaway grounding sheet.
It's a premium underlay built for people who want reliable grounding without sleeping directly on metal fibres.
Secure Fit –
adjustable straps hold it tight all night.
Breathable Cotton – soft, cool comfort while you sleep.
Carbon Patch–
locks cord to the grounding surface.
Stainless Steel Fibre –
medical-grade 316, non-corrosive.
Easy Care –
machine washable for daily use.
Extra Protection –
under-sheet use, works with PJs too.

Enjoy the benefits of grounding every night
- Deeper, more restful sleep
- Reduced inflammation
- A calmer, more balanced body
- Reconnect with the earth while you sleep
How does grounding work?
Grounding connects your body to the earth’s natural supply of electrons through a conductive path while you sleep. These electrons may help support the body’s electrical balance, reduce oxidative stress and promote a calmer recovery state. Now you can enjoy the benefits of grounding from the comfort of your own bed.
The deeper science behind grounding
For most of our lives, we have very little direct contact with the earth. We wear shoes, spend much of our time indoors, and rarely walk barefoot on natural surfaces. Grounding sheets help you reconnect while you sleep.
The body is made up of electrically charged atoms, including protons, electrons and neutrons. Our cells use electrical signals to help the nervous system communicate throughout the body.
The earth carries a natural supply of free electrons. Grounding allows the body to come into contact with these electrons, similar to walking barefoot on grass, sand or soil.
Research shows grounding may support sleep, recovery, relaxation, circulation and the body’s natural electrical balance. Many people choose grounding because it is simple, passive and easy to use every night.
Effortless Grounding
Install once and relax — grounding works automatically each night, bringing balance and deeper rest.
Built to Outlast
Protected beneath bedding, it resists sweat and friction — keeping conductivity strong for years.
Safety Tested
Proudly Australian with 9 years’ experience, backed by strict local testing for safe, restorative sleep.
Simple Comfort
Use with your own bedding and pyjamas — grounding flows through fabric for comfort and freedom.
Sleep Deeper
Grounding can help calm the body, support deeper rest, and reduce morning fatigue.
Fewer Quick Fixes
Better sleep and recovery can mean less relying on temporary over-the-counter fixes.
Less Pain & Inflammation
Support blood flow, recovery, and overall balance while you sleep.
Less Aches & Stiffness
Wake feeling more comfortable, with support for circulation and inflammation balance.
Before – after earthing
Studies, including thermal imaging, have shown significant reductions in inflammation and pain after Earthing, with some patients experiencing rapid relief from chronic conditions after just a few nights of grounded sleep.

What Can Grounding Help With?
Studies have observed changes in inflammatory markers following grounding, suggesting it may support the body’s natural recovery processes. Many people report improved comfort, reduced soreness, and enhanced overall wellbeing.
Grounding may help support nervous system balance and healthy circulation, which can contribute to greater comfort at night. Many users report calmer legs and a more restful sleep experience.
Research suggests grounding may support healthy circulation by promoting the body’s natural electrical balance. Improved blood flow helps deliver oxygen and nutrients throughout the body, supporting overall wellness and recovery.
Grounding has a calming effect on the body and mind by regulating the nervous system and lowering cortisol levels. This can significantly reduce feelings of anxiety and stress and enhance overall well-being.
Grounding aids pain reduction by lowering inflammation, calming the nervous system, and improving blood flow. It helps reduce muscle tension and promotes healing, providing natural relief from chronic and acute pain.
Research shows grounding may support the body’s natural recovery processes following physical activity. Many people report reduced muscle soreness and feeling more refreshed after exercise.

Amazing fit! Easy to adjust and fits our king size well. Three weeks in and my hip pain is almost gone, sleeping deeper and longer! Excellent quality.
I’m blown away, had edemia due to heart problems and arthritis for many years, now my swelling and pain have gone! I can’t believe it! Really it’s the best thing I have ever purchased, I also have no pain in my wrist from carpel tunnel! Just tingles! Thankyou for this product and I’ve only had it 1 wk on my bed, still realising what’s happened to me 🙏
A good quality product that arrived very quickly. It’s giving me a full night’s uninterrupted sleep and reduced the swelling in my arthritic hands. Highly recommend.

FAQ
Most frequent questions and answers
Similar to a soft light denim material.
No. We don’t recommend using mattress protectors, thick toppers or padded underlays between your body and the grounding product, as they can create too much interference and reduce conductivity.
For best results, place only a normal bed sheet over your Premium Grounding Underlay or Grounding Bed Mat.
Yes. Our Premium Grounding Underlay is designed to sit under your normal bed sheet — fitted or flat — so you don’t need to sleep directly on the conductive material.
For best results, avoid placing thick waterproof mattress protectors or heavy padded layers between you and the underlay, as these may reduce conductivity.
Yes. You can still wear PJs.
Direct skin contact isn’t needed. Your body can build up voltage from nearby electrical appliances and wiring, which can be tested with a multimeter. The underlay connects you back to earth through your sheet and light sleepwear, helping discharge that buildup while you sleep.
What’s the difference between Premium Underlay Sheets, Earthing Bed Mats and Fitted Earthing Sheets?
Premium Grounding Underlay Sheets
Used under your normal bed sheet. They don’t require direct skin contact and only need washing every 4-6 months.
Cotton/Silver Fitted Grounding Sheets
Used like a normal fitted sheet and require direct skin contact. These can be machine washed as needed.
Black Premium Grounding Bed Mats
Used with a normal bed sheet over the top. If cleaning is needed, simply wipe down with a non-abrasive cloth.
All three options can effectively ground the body. The main differences are the material, feel, setup and cleaning method.
Stainless steel (316) is medical grade and can handle regular exposure to corrosive elements, making it our most durable earthing product.
Machine wash every 4–6 months on a cold or warm delicate cycle with mild liquid detergent. Line dry only. Avoid bleach, fabric softeners, whitening detergents, oils, tumble drying or high heat.
Yes, all power boards, double adapters and extension cords are all designed to connect to the earth outlet.
No — it’s impossible for the earthing sheet to conduct electricity when it’s only connected to the earth pin of your power outlet. The power point doesn’t need to be switched on for it to work. The top two pins of the plug are plastic (non-functional), and only the single bottom pin connects to the earth, which safely grounds the sheet.
Australian homes are required to be earthed for safety, but a multimeter is an easy way to check that your grounding product is working correctly.
Unlike basic continuity testers that only show a green light, a multimeter can show the voltage in your body reducing when you are grounded.
120-Day Trial
Try your Premium Grounding Underlay properly at home. If it’s not for you, you can return it.
3-Year Warranty
Covers manufacturing faults and product defects.
Optional 10-Year Conductivity Cover
Available as an optional add-on near the Add to Cart button.
Because our underlay sits protected beneath your fitted sheet, it only needs washing every 4–6 months — far less than fitted grounding sheets that are exposed to sweat, friction and weekly washing.
If added to your order, this cover protects your underlay’s conductivity for up to 10 years under normal household use.
Our Premium Grounding Underlay Sheets are cut to fit real mattress sizes — not a one-size-fits-all sheet.
For most beds, simply choose the size that matches your mattress:
Single: 200cm x 70cm (fits any bed size)
King Single: 203cm x 107cm
Double: 203cm x 140cm
Queen: 203cm x 153cm
King: 185cm x 203cm
Need a larger fit?
The sheet can also be rotated sideways for wider beds.
A Queen underlay can fit a King mattress by turning it sideways, so the 203cm length runs across the width of the bed.
A King underlay can fit a Super King mattress the same way.
This covers the main sleeping area of the body and only leaves the pillow area uncovered, which is fine because your body is still resting over the conductive section.

I was very optimistic but have been able to sleep without any hip pain, definitely think it helps with inflammation.
June 17, 2026
Urban Hippee were quick to respond to my order, and had it to me within 48 hours. Fabulous! My husband and I noticed the improvement of our sleep the first night. I am so glad that I purchased it.

Great all-round experience.
Great product, great service, great price, great all-round experience. I did my research on this product and landed on Urban Hippee. I’m glad that I did.
June 14, 2026
Exceeded expectations by a mile!
We purchased the Premium Grounding & Earthing Sheet hoping to feel the benefit in sleep quality we had been told about by one of our patients.
Ordering was simple, delivery was fast, and wow – the difference it has made to our quality of sleep is amazing. Not a big investment to feel much more “rested” every day.
June 13, 2026
I have used my earthing under-sheet for several months. I love feeling nature wrapping around me as I rest in bed. Now I have purchased another one for a dear friend for his 70th birthday.
June 13, 2026
I did not think it would work
But my husband used to get cramps every morning in his legs.
But now he has not had one so that is amazing
It really does work as I am now getting a good nights sleep it amazing.

Review of Premium Grounding Pillow Cover | 35cm X 55cm and Premium Grounding & Earthing Sheet | Underlay | Queen
Sleep is so much better, wonderful, and postage was fast. Couldn’t be happier 😄
June 10, 2026
Easy to order and a quick arrival. I had one question I emailed and Urban Hippee responded efficiently.
I am usually awake after two hours to go to the toilet, slept five straight last night after five nights on the underlay. When I wake during the night I am going back to sleep more quickly. I previously had a grounding fitted sheet which was cotton and silver, a bit rough and I did not realise that the endless washing damages the silver and effects its ability to ground. The bonus mat (a wonderful extra) is in a pillow slip, and my cats are grounding during the day too. I am very happy.
