Our playgrounds are all closed and our backyard won't fit a swingset so this is PERFECT for our 4 and 6 year old (and I suspect it will be for several years).  Our kiddos immediately started playing on it and we can see their confidence improve (like playgrounds can do).  We used a large blue tarp we had as a cover and voille!  its a fort!  I researched domes and found this to be the highest quality I could find.

Highly recommend.
