INDOOR & OUTDOOR DOG BED – In line with our mission to include dogs on every adventure, we created the Sleeper to ensure your dog has a comfortable bed, no matter where they are.
QUICK, EASY & DURABLE – Thanks to a flush air valve & mildly elastic material, the mattress is quick & easy to use, inflating with just a few breaths. The exterior is soft to the touch, but also strong enough to prevent punctures.
MADE TO TRAVEL – Constructed to eliminate the hassle of bulky dog beds when you’re traveling, our lightweight, space-saving design rolls up compactly to fit in the included carrying case, which easily fits into the side pockets of your K9 carrier.
INCLUDES SLIP COVER – The soft slip cover not only helps eliminate noise as your dog uses the bed, it increases the durability of the mattress against wear, tear, and punctures. Plus, it’s washable! Simply remove to clean periodically.
PERFECT FOR THE POP-UP TENT – This bed is designed to fit into our K9 Pop-up Tent (sold separately) or any other dog kennel. The combo is ideal for hot, sunny days when your dog wants to escape into the shade.
AVAILABLE IN TWO SIZES – The Small/Medium size is 3” x 18″ x 18″ when inflated. If you have a larger dog breed, consider the Large/X-Large size.
