content: We live in AK and so we thought we needed to find something to keep our toddler active while being cooped up during the winter. Our son loves it...WE HATE IT! It takes up almost the whole living room...that's not the bad part! There is only a bottom in the Large section. The two medium section are open on the bottom so there are always balls everywhere! We bought extra balls (which you need) but our house turns into a ball pit! But we make it a game with our toddler to pick up the balls...but WARNING you will be finding balls for days!
