Got this to hang in the garden for my 3 yo daughter, and it's a real hit.
The flexible seat wraps around the chid and gives them more confidence than a 'grown-up' swing, so they're more inclined to use it, and it has seen a lot of use - appears to be highly durable too.
As it's flexible it's also comfortable for swinging on the tummy, so the kids like just hanging out on it.
Strong enough for adults too - I'm 95kg and I've had a go (although I didn't get too vigorous to be fair, but I'm certain the bolts holding it up would fail before the swing itself).
Highly recommended, especially if your kids are wary of upgrading to a 'big kids' swing.
