It totally depends. If I'm tired enough, I can fall asleep anywhere (have even been known to nod off for a second or two standing up outside on the playground with my class....ssshhh, don't tell!) On our very comfy reclining couch, I can fall asleep reading or watching TV or listening to music, especially when I am under my cozy faux shearling fleece blanket (known around here as "Big Red" since it's red polar fleece on the other side). But in bed when I turn in for the night, I tend to be more particular. I need 2 pillows and near darkness (night light in the bathroom next door but not in the bedroom), cool air, no TV, and prefer no music but can handle very soft relaxing music. Hubby & I don't always mesh well because he likes it colder than I do and HAS to have the ceiling fan, which I despise.He also loves going to sleep to the TV. But I give a little and he gives a little and we meet in the middle and manage to both sleep pretty well.
