The tightly felted wool fibers not only provide water resistance but also render the pad naturally flame retardant, offering an additional layer of safety for your home. With elastic straps designed to hold the pad snugly in place, you can rest assured knowing your mattress is protected, whether from children's accidents or the occasional spill while co-sleeping with pets.
