Thus the ceiling (2m * 2m) bought as a substitute for a 1,35m x 2m ceiling. It sleeps very well in it, and now I have enough material when I turn on all sides me. It wraps a good one, it keeps you warm and is easy. From the same supplier I have to still bought bedding that is also ok. And very important, the ceiling remains in the bed linen, it does not slide around.
