I bought a dome climber to match our Lifetime swing set. My grandchildren are ages 8 and younger.  All the children 2 and older are loving this dome. They come up with creative ways to play, and it is fun to put a tarp or blanket over it and make a castle, clubhouse, etc. (I plan to get the Lifetime cover as well.) I worried the little ones would fall through and hurt themselves, but it seems to be engineered so that those who can climb high are strong enough to hold on and swing down, while those I would worry about are not quite able to climb high enough to be in danger. The instructions were very clear--it probably would have taken one helpful son-in-law 1 1/2 to 2 hours to put it together alone, but it took 3 hours with his team of very young "helpers."  It is easy to move. Of course, it looks great and is very sturdy and well made, like all Lifetime products I have tried. No nicks or chips--it is just a fine product.
