Some basic models may be easier to cart around because they don't have any extra parts. You can also look for bags that leave the play yard's wheels free, so the whole thing can be rolled once it's packed up. If you plan on taking frequent trips (especially by air), you might want to consider a heavy-duty bag that you can buy separately, such as the Rover Gear Easton Travel Yard Bag (about $34).
I have hard wood floors and needed a playpen for my 8 month old daughter who likes to climb everything. I am so happy with the item I purchased and wish I had purchased in sooner. The ease of mind of being able to leave the room with my baby peacefully playing in her pen is amazing. It's large enough that it takes up the good majority of my living room, but not too large. However, it would be easy to remove panels to adjust the size. We never use the gate as it is low enough to step over, but tall enough where she cannot climb over the railing. The gate does move around and can be adjusted to fit whatever shape you need. I have not fussed with the suction cups to get them all to stick down, however, it is sturdy enough without doing so.
Only had a little while, but really not worth the money. Very flimsy can’t even lean against it when sitting in it. I bought it so I could let my son play while I did things near by; however I can not leave him unattended bc the way it’s made has perfect slots for them to be able to put feet in and climb up. Material is hollow plastic so it squishes also if pressed hard.
Nice to keep baby out of trouble at home. Once he became mobile we had to do an "upgrade" as we noticed he was starting to hit his head on the X shaped metal bars. We tried some alternatives but the best so far was wrapping the metal bars with pool noodles (see picture). You'll need 8 pool noodles and some cuts (buy some extra in case you mess up). Use 2/3 of a pool noodle to wrap the internal bars and the remaining 1/3 to wrap half of the external bar. The pieces will also need a longitudinal cut along the length to fit the bar in. You'll also need some small cuts in the middle of the longer piece to fit the center rivet, where the mesh is attached to the bars. We got the pool noodles at the dollar store nearby for less than $10 and since ... full review
