I use play pens and cots with sheets. I use the three bedrooms upstairs. Three in my room, one in my daughters room and one in my sons room. I have had an older child, three years old not needing to nap as long and kept the others up so I brought him down to main level where my playrm is also. He slept on the couch. I have also brought down a cot and just put it in the middle of the floor. It worked well he slept solid and didn't wake easy so I was still able to clean up and do my stuff around him napping.
