Trampoline dog beds are made from a heavy duty Australian made cotton blend canvas which will repel water but still "breathe" to allow air to circulate -a far cry in terms of quality and cost from cheap imported hessian or jute canvas or even jute bags and cheap plastic mesh.
A few very important points to remember. Unlike many other beds on the market these beds are a proven product having been marketed continuously since 1975 and they are the only pet product of its kind ever to have won an Australian Design Award.
