Full Side-by-Side Comparison
- The only UK manufacturer of earthing bed sheets, pillowcases, and meditation mats outside China — products made in Herefordshire, not imported
- Founded and run by Steve Dalloway — qualified electrical engineer — the same professional background as Groundology's Seb Francis and Better Earthing's Peter Griffiths
- Trading as Byretech Ltd — Unit 51 Padgets Lane, Redditch, Worcestershire — a registered, verifiable UK business entity
- Made-to-Measure Fitted Earthing Bed Sheets — the only brand in the GroundingMatrix global index offering custom-dimensioned earthing sheets for non-standard beds
- Three distinct conductive technologies across three product lines — copper rivets (sandals), GroundSync™ carbon-infused rubber (slip-ons), BIOS clay-copper composite (sneakers)
- The only brand in the GroundingMatrix grounding footwear index that explicitly combines all four barefoot shoe principles simultaneously: zero-drop, wide toe box, thin flexible sole, no toe spring
- Natural materials prioritised across the full range — wool, cork, leather, castor bean oil — over synthetic alternatives
- Four grounding sock formats — ankle, half-cut toe, low-cut toe, no-show — in single through 10-pack quantities — the most comprehensive grounding sock range in the index
