Yes it's portable, I have one of these for my son, and they are absolutely wonderful. He is 5 1/2 months old and still uses his. We started out using it in our bed in between us, he is our first and we wanted to keep him close. Now he uses a bassinet and is going to be in a crib soon, but we take our co-sleeper everywhere with us. He takes his naps in it, and when we stay overnight at family or a friend's house, I don't know what we'd do without it. I absolutely recommend this to anyone.
just looked one up at wal-mart for $37.00 they are nice to have even better if your someone who likes to camp and no room for playpen this fits nicly beside you in a tent or on a bed in a camper.
