On Thursday Max Vasilalatos and I fell into a discussion of how we manage to sleep sitting up when health considerations require it. I have a wedge I can use in my bed, and for many months I slept sitting up in a reclining chair. Max volunteered that she had a husband for this purpose, but it wasn’t entirely satisfactory. I was puzzled until she described the object — not a human being — that she used for this purpose. The Wikipedia account (in the pillow entry):
A husband pillow (also known as a boyfriend pillow) is a large, high-backed pillow with two “arms”. It is used to prop the user upright while in bed or on the floor, as for reading or watching television.
