Mine is full sized. Got a good Sealy, one down from the best they had, five years ago. Then put a two-inch memory foam over it, and then a quilted cover, so I can wash it when I change the sheets. Then the 1000 count cream colored sheets, and pillow cases, and a plain cotton blanket. (Brown) I also have three different cotton quilted comforters, which mostly, I don’t use. There are two standard pillows, of which one generally gets thrown on the floor during the night.
I have a second pair of sheets, in dark red, only 600 count, which I use if I don’t feel like waiting for the cream colored ones to get through the laundry (Which is four loads for all the bed clothes, plus drying, and who has that kind of time?)
One of the quilts hangs over the window, to block out the light, most of the time. (I sleep until noon, and the sun shines directly into the window shortly after sunup, so I have major black out stuff in place, and still need the quilt to catch the last of it.) The other is on a chair, near the bed, and mostly stays there, often with clean laundry thrown in a pile over it. (sometimes vice versa)
I have a Futon in the living room, and a full set of the same quality sheets, and blankets, and comforter for it, in the drawers beneath the frame. No memory foam, though it has a 1 inch foam top built in, and folds out into a full size bed. Very comfortable, considering. No black out stuff, though, and it gets very light in there come dawn.
