Fab fun for younger kids. Easy to assemble and supremely strong. We've had two of these for our boys (now aged 6 and 3). Newest model added extra screw fixings, more for peace of mind than actual safety, I'd say. Four lightweight panels and slide attachment push and lock into place with moderate force and once assembled, which takes only a few minutes, is there to stay. Recommend rubber mallet for disassembly.
Will fade and suffer usual effects of our weather if left outside, so best stored away. One of ours passed to kids nursery and they all adore it. Our boys loved to climb, crawl and slide and we had it indoors. Not suitable for very small rooms, but superb for garden. Best for kids from early walking stage upwards.
