We bought this because we got Great Dane puppy and needed to limit her wandering until she was potty trained. We put a rubber-backed sheet under it (like the ones you put on kids' beds if they are bed-wetting age.) The flexible panels allowed us to adjust the shape of the pen to fit the spot we had in the room. The gate locks were sturdy too and stayed in place even when the puppy jumped on the panel. The quality of the vinyl is nice and sturdy. Even though she's now out-grown it (and, more importantly, is house-trained) we've hung on to this because the quality was so nice and the price was great.
