Microfiber feels as soft and gentle as the coziest cotton or down but the synthetic, allergen-free material is tough enough to last for years. It has naturally-occurring anti-microbial properties due to the unique characteristics of these tiny fibers. A bed is just a natural evolution for something so velvety and comfortable. The Dirty Dog Rectangle Beds upgrade the interior with a high density cushion for maximum comfort. Quilted suede fabric sides ensure these beds are as elegant as they are tough.
