LO is fast outgrowing his activity gym - it's the kind with four low, soft sides (this one: http://www.toysrus.com/product/index.jsp?productId=13338593) and he loves to roll around in there and play with his toys. He's nearly mobile now, and has managed to escape the gym.

That got me thinking - is there another type of play space / activity gym that would work for a crawling baby? Like a cordoned-off play space that we can make safe for him? We would still be watching him, of course, but it would be nice to have an area where he could play with all his toys. What do you guys use? Just to note - we live in a relatively small apartment, so we don't have a ton of space.
