We bought one of these last week @ walmart the one we got is like the dome one on the top it has a krinkle pad that you can put in the bottom of it. Tia loves it she will play in it everytime we get it out she goes crazy running in it and rolling around. The only thing I don't really like is it collapses on her everytime she plays in it it wont stay up but it doesn't seem to bother her
. Maybe if you have several of them it wouldn't.
