Bolster beds offer a sense of security and extra comfort. Our sturdy outside bolster is made from a strong, waterproof canvas and filled!with recycled shredded fibre to offer great quality, durability and comfort for your pet for years to come. As with all our bigger beds, our pillows are filled with a recycled polycotton fibre, that ensures amazing support and insulation against the cold. Due to the filling we use, our beds are on the heavier side and will not easily collapse. Handles are provided for ease of carrying. The inner pillowcase is reversible, made from plush coral fleece on the one side and a durable, cooler poly-cotton on the other, offering the perfect snuggle come rain or shine. Replacement Pillow Covers and Inners Available Separately.
