We have a play yard set up in our family room for Kiki. It was the play yard we used for our two daughters and thankfully I saved it in our attic. I am not sure of the brand, but it has 6 panels and made of plastic, very sturdy. I am sure you could find a similar one at Target or Toys R Us in the baby section.
Our family room is carpeted so I went to the fabric store and bought a few yards of vynal on a roll and placed it underneath. It has solved our problem of having to scrub carpets as Kiki uses her pee pee pads in there only and if she misses the pad, I just wipe up the area with a Clorox Wipe. Kiki is almost one year old and we still put her in the play yard when we have to go out for a couple of hours. At least we know she can't get into trouble.
