i saw kids mall at imm selling it at $150 i think. I think can use it when baby starts to crawl but it's provided you have big space to put it cos if it's just a 4 panel one is as big as a play pen. you have to buy 6 panels to fit in a single bed size. But they sell in 4 panels per set so you need to share. For me i spare out a room n put crawling mat in the whole room with only his toys n mat so he'll crawl n play in there.
