Generally, Ella takes her afternoon or mid-morning nap on the family room couch. It's much easier for me to get her to sleep and lay her there than to try to carry her 28 lbs up old creaky wood stairs to her bedroom and hope she doesn't wake up. Works for me. However, my mom gave us a down-alternative comforter for our king size bed for Christmas. When all three kids were home ill, we opened it up and made a little nap mat on the cushy carpeted floor. They napped on it, snuggled on it, watched tv, etc. while resting up.
It makes such a cozy little nap mat, I'm not in a hurry to put it to it's rightful use.
