We got a monstrosity from Wickey, two towers, a wobbly bridge, rope ladders, two swings, slide, firemans pole etc. Have to say it was quite an effort to build, but my boys are on it loads. We put a border around it and used rubber chips underneath. Sometimes I hang my punchbag from the swings and I will be putting some gymnastics rings up there too, the swings are probably used more than anything. Luckily I have a big garden, so it isn’t too obtrusive and it looks nice anyway.
Not sure I would buy the same make again, it is great now built, but it wasn’t easy. We expected a giant airfix model ready to go, but you have to measure, mark and drill almost every bit of wood!
