This was ordered for my daughter's 2nd birthday, and while it is great fun for the kids, it certainly isn't made of "strong waterproof canvas" as the description says. It's actually made of thin, untreated linen, like bedsheets! What a con.
Also, the one we received has a totally different design from the one we ordered too. The motifs are spray-painted on, and the whole thing feels like something daddy could have knocked up with a bedsheet and a can of spray-paint and some garden canes. The kids are having fun playing with it anyway, but I have to say that Amazon & the manufacturer need to sort out this grossly misleading product description.
