Enjoy a night of total relaxation with the Purecare Copper Mattress Protector. Stay refreshingly cool all night long, thanks to the copper and nylon thread woven into the knitted cover. These threads actively regulate your temperature throughout the night so you stay cooler for longer. Infused into the fabric is a smart silver chloride treatment that provides strong antimicrobial properties. This treatment enhances the protection of the mattress and yourself. You can sleep easy with full knowledge that you will have a fresh, healthy rest. With MiteTight® seams and waterproof design, this protector defends against dust mites, moisture, allergens, mould and mildew. Each one of these factors can cause damage, deterioration, stains or odours on the mattress. Finished with a 12 Year Warranty but if bought simultaneously with a mattress, it becomes a 12 Year Guarantee.
