Superior Pet Goods Extra Thick Hessian Dog Mat features with an extra-thick piece of foam for added support. A practical and naturally hypoallergenic mat for any pet, inside the 100 percent biodegradable cover is an 8 cm thick piece of foam that has been treated to control dust mites and other household bugs that trigger allergies and asthma, as well as bad odours and mould. Traditionally used in kennels and crates as it can hold its own when exposed to moisture and the elements, this mat is versatile and can be used indoors and outdoors. Comes in large size.
