A carrier, a car seat and a cosy bed: travel that takes your pet's safety seriously.
The Sleepypod Atom is a sleek, lightweight carrier for cats and small dogs up to 5.4kg (12 lbs). Lined with cosy Ultra Plush bedding, it is just as suited to a trip to the vet as it is to carrying your pet through a busy terminal, and it doubles as a comfortable napping spot at home. Soft to carry, calm to travel in, and built to a safety standard that sets Sleepypod apart.
Used as a car seat, the Atom's PPRS Handilock restraint system secures your pet so they cannot be thrown in a collision or hard stop, while helping to absorb and reduce the forces reaching them. This is not a marketing claim: the Atom is put through the same dynamic crash testing used to certify child safety restraints, tested to US, Canadian and EU child-safety standards, and independently certified by the Center for Pet Safety for pets up to 12 lbs.
