I'm sure any cat owner can see how great this idea is straight away - a cat bed that hooks over your radiator.
Constructed around a sturdy metal frame the Canac Cats Cradle radiator cat bed has a stationary front bar and hinged sides, so you can adjust the distance between the hooks to avoid fixings or other obstacles behind the radiator.
The bed folds flat for easy storage, although our cats seem to enjoy the radiator beds regardless of whether we're using the heating or not, so you probably wont need to store it.
The cover is a soft fleece material, which hangs like a hammock across the frame and is easily removable for washing.
This is the single depth radiator version here, also available in a double radiator size
