We researched Grounding and found the benefits to be legitimate. We had previously purchased a grounded fitted bed SHEET, but read that the silver threads in those sheets breaks down quickly after a number of washes. I wanted a sturdy yet comfortable queen sized grounding MAT that would fit UNDER our existing bedsheets, so that we could wash our sheets without worrying about wrecking the grounding.
Looking at several comparably priced competitors, I saw cheap quality material that wrinkled, didn't lay flat or looked like it would deteriorate quickly, smaller size mats that didn't cover the entire surface of stated bed sizes, and mats that didn't secure properly with straps.
Two comparable quality competitors were considerably more expensive.
When this product arrived it was nicely packaged, didn't need airing out like some of them do, and lay beautifully flat with no wrinkles, and fully covering our Queen bed. Our mattress is a Tempurpedic deep-pocket, and the elastic bands slipped around it easily and securely. We didn't need the additional provided clip straps to secure it.
The ground strap setup is sturdy decent quality.
We've been using it for a couple of weeks now. It's comfortable (not even noticeable) & we seem to sleep more soundly and wake better rested. I'm impressed.
The only strike was that the ground tester that Grooni provided Free with the product (bonus) was actually a dud in our case, but that's okay. The product itself is excellent and reasonably priced for what it is. I think it will last a long time and be well worth the money.
