Softer Material: More comfortable compared to our current black carbon Sleep Mat material. Thinner Material: About half the thickness of our current black carbon Sleep Mats so it won’t trap heat against your body.Smooth Surface Area: There are no perforations in the surface area of these Sleep Mats so not only are they more comfortable, but you’re 100% grounded no matter where you move. More Sanitary: The hypoallergenic nature of carbon helps combat allergens in your bed. With no perforations, these covers not only ground you, they also create a physical shield against the dust and mites living in your mattress. Easier Cleaning: No perforations on the surface makes it easier to wipe down. Easy to put on: Simply slide the straps around each corner of your mattress and you’re done! No more wrestling to get straps around the entire mattress. More Durable: So far, we’ve tested these products for 5+ years and they are as conductive and blemish-free as the day we started. While the springs in your mattress may fail you at some point, the conductivity of your Sleep Mat won’t. Our new conductive material is designed for a lifetime of conductivity, and like all of our products, it comes with a one year warranty.
