K&H Bucket Booster Pet Seat Collapsible is just like the K&H Original Bucket Booster, but has a unique "knock down" design that ships collapsed and can be assembled in minutes; then knocked down/collapsed again for space saving storage. This collapsible pet car seat provides a safe and controlled location for your pet to ride, all the while elevating them for an easier view out the window. The K&H Bucket Booster has a durable heavy-denier fabric exterior and contrasting plush quilted fleece interior for your pet's comfort. Designed to fit in either the front or back seat of your vehicle, the contoured back ensures a snug fit inside of your vehicle. d.
