This Dreamy Sleepypod Atom is more than a pet bed, more than a carrier or car seat: it's a lifestyle. It's your pet's personal space, designed to fit his/her individual needs. Sleepypod pampers your pet in luxurious ultra-plush and foam, providing comfort and security. In times of fear or stress the dome top can be opened or closed by unzipping the center and adjusting the sides. An optional warmer is available for extra coziness on chilly nights or when a human lap just isn't available.
