This fabric next swing by Hedstrom is a great price right now, reduced from £129.99 to just £51.92 over at Amazon.
There's one of these nest swings at my local play park and my kids literally can't get enough of it. I love it too because all three kids can fit in it at once, which means fewer squabbles over whose turn it is to go on the swing.
This one is suitable for little ones aged three years and over, and the powder coated steel frame is robust and durable. It also comes with ground pegs for extra safety and stability.
Delivery is free, too!
