Abstract: A bed for a pet includes a substantially hollow flexible shell including a top wall, a bottom wall, and first and second outer walls interconnecting the top wall and the bottom wall. A plurality of substantially parallel barrier walls are disposed within the shell. Each of the barrier walls extends from the bottom wall to the top wall and from the first outer wall to the second outer wall. Each pair of adjacent ones of the barrier walls define a respective channel therebetween. Fill material is disposed in each of the channels.
