We bought these for our twin 8-year olds, and they love them. My brother put them together in a few hours. The only downsides are the lack of a step-through at the top of the ladder, which makes for a somewhat awkward entry/exit, but our kids don't seem to be bothered by that. It's also a bit wobbly if not braced by another piece of furniture or strapped to the wall. We really appreciated the fast, free shipping--and delivery on the expected date, which is key for such large boxes.
