Great hammock, versatile for use on windows, balconies, or doors
I bought the lounger to attach to the railing at my window (yes, it's cat-proof). My cats now love their hammock lookout. When we're not using it at the window, I hang it over a door and my cats climb onto it from a sideboard and sleep there at night. Super stable, well made.
By the way: It doesn't fit on a radiator at all – but I didn't buy it for that anyway.
