This versatile low profile bed combines the softness and comfort of "Eco-Tech" polar fleece, with the rugged durability of waterproof nylon. Also makes a great travel or crate bed. Each bed diverts up to 20 plastic pop bottles from landfills. Overstuffed with "super-loft" recycled fiber. Circle "tufting" creates a stylish mattress look while preventing fiber from clumping or shifting.
