Worried about Fido’s safety while in the car? Kurgo’s Skybox Rear Booster Seat is a dedicated space for your dog to be comfortable and safe during car rides. It’s recommended to use with a crash-tested harness to further secure your pup in the booster seat. The tether and rear webbing work with any seat belt, so you can use in any car or truck. While on a road trip, the booster seat can also double as a travel bed so you can minimize the amount of gear you need to bring for your dog. Suitable for small dogs up to 30 lbs, but is recommended for dogs up to 20 lbs since heavier dogs have larger body masses. Doubles as a convenient travel bed & folds up easily when not in use. Interior dimensions: 15 1/2"W x 8 1/2"H x 12 1/2"D
