Coolaroo pet beds are unique and differ from other pet beds by using a cot style design that takes advantage of the Coolaroo "breathable" knitted fabric for ultimate pet comfort . They are elevated off the ground to promote air flow on all sides, including underneath to keep your pet cool and comfortable. Our unique fabric is also flea, mite, mold and mildew resistant. It features a lightweight, yet strong and durable powder coated tubular steel frame that is easy to clean by simply hosing it down when needed. It is light weight and portable making it ideal for hunting, camping, fishing, boating or traveling. The bed comes fully assembled and the UV stabilized fabric comes with a five year warranty. Three sizes: Large (51.5” X 31.5”), Medium (3' x 2'), and Small (2'3" x 1'8").
