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