Kerbl Pet Cat Deckchair Sundowner

I was specifically looking for something for my balcony, which is only half-covered. It also says it's suitable for indoors and outdoors. However, the rollers that the scratching lounger is stretched over are made of cardboard. I can't imagine that will last long in the rain. The rest seems pretty sturdy. But I find the 'outdoor' claim misleading. For me, outdoor means it's weatherproof.
