I bought this about a month ago when my baby first started crawling. My three must-haves were sturdiness, a fairly large play space, as well as the convenient ability to collapse or fold it up for easy storage so that it wouldn’t become a permanent fixture in my living room if I didn’t want it to be.I was pretty sure I wanted one of the sets with plastic panels such as Toddleroo that you can take apart and put in any shape, but I quickly realized from reviews that they are flimsy/unstable and too lightweight to stay securely in place, which was a worry for me, since my baby is cruising now. Also, turns out plastic hinges are fragile, even for the not so affordable price of $100+! Ridiculous.This particular play-yard met all of my must-haves in addition to being one of the most affordable ones that I found on Amazon, and lacks a lot of the issues that other types of play yards have.First, it’s made of sturdy materials and comes all in one piece. The frame is mostly metal with some very thick and sturdy plastic that I do not worry about breaking at all. The sides are mesh/net like a Pack and Play with a little give, but not so much that it’s a problem if your child leans on it. My baby presses his face into it all the time and it only bows out a little while offering plenty of resistance. The bottom is a fabric material that also reminds me of a Graco Pack and Play, or like a tent material. It has a construction reminiscent of those collapsible metal lawn chairs and is just as easy to open and close, and when fully extended and locked into place, it’s extremely sturdy. I was able to stretch it open and lock the struts in place on my own the first time I tested it. It does not slide across the floor even when my child pushes on it, from either side, due to having 8 sturdy feet. But it is still lightweight enough that I can lift it/drag it across the floor if I need to vacuum around it, etc.The play yard has also held up well to my baby learning how to pull himself up on it. Even when he leans on the sides or hangs on the edge, it supports him, doesn’t sag or droop, and doesn’t show any dangers of ripping. It doesn’t come with any kind of padding on the bottom, which could be a negative if you were planning on using this playpen in a room with a hard floor, but it does appear to be waterproof. I have mine on carpet, but I also purchased a thick and fluffy circular rug to put in the bottom of this because I wanted it to be more fun and comfortable for my baby, so I’m not sure how tear-resistant it would normally be. I was willing to pay extra for the 8-sided model instead of the 6-sided because as I said, I wanted the largest space possible to prevent baby from feeling too confined, which would make him less likely to enjoy his time inside of it. The 8-sided model is large enough for 3 or 4 adults to sit comfortably inside along with baby, and it’s stated in the product dimensions that it is 5’ across, which seems accurate, because the 5’ rug I bought fits edge to edge.Of course, I made such a big deal of getting a play yard that I could easily pack away, but I have not done so in the month since I bought it. I know I will one day though, and probably even travel with this, so I appreciate having the option. It’s not the ugliest either, which makes me feel okay about leaving it out year-round. Again, that it collapses also means that there are no loose parts or assembly required, like some of the large square play yards. A huge plus, especially if you plan on putting it away, traveling with it, or moving it around from time to time.My parenting tip is to hang toys around the edge with the plastic baby toy rings, as this will add some extra fun/interest for your baby while inside the pen. My baby has outgrown several space-taking baby toys such as his Fischer Price ball pit/play mat and his FP Kick and Play Piano Mat that all had hanging toys I detached and added to this playpen.My final impression is that this is a quality product that I will be able to use for many more years as long as it continues to hold up. I would recommend this play yard to anyone in search of a safe place to set your baby down.
