Rosierum, That's a really cute video of your two in theirs. It does look like they have enough space....I'm wondering if perhaps I'll get one too. From the dimensions it didn't sound that big but it's probably just my poor maths. I tried to visualise how big it would be, as my Yossi is quite a big boar and Little Bud is not so little these days either, but I think I underestimated.
Those who already have this ball pit...Would you say it's quite quick & easy to fold down? (i.e. if you had to fold it away every day would it still be practical or would it get too annoying?!)
Are you are familar with C&C's? is the same size as a 3x3 i.e. : 42x42 inches.
... and yes my children have had things like this and are easy to pack away
