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.
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).
Love this playpen! Sturdy, bright and fun. Has a few toys inside that even bigger kids (3yr olds) want to play in it. Big enough for multiple children to play in it at one time. it has suction cups under each panel that I'm hoping will work good on our tile floors when they get installed in a few weeks. I found a mat (patchwork toddler play mat) that is 1.5 inches thick and fits perfectly inside that will vision little ones falls.
The quality is certainly there. The mesh seems very strong and its very easy to collapse and put away. The same goes for putting it together. It just folds in or out. The reason for not giving it 4 stars is the padding on the floor. We had to put additional patting as its too hard. So keep that in mind when buying this play pen. I would recommend for its portability and the zipper at front.
