What are Comfortables?

[stormdog]

A talk with a professor reminded me of this 1858 ad for the Kenosha Water-Cure that I turned up while researching Pike Creek.

The ad notes that that "invalids will bring six crash towels, two cotton or linen sheets, a flannel blanket, and two comfortables."

What are comfortables in this context? Underwear? Something else?

I think it may be what we used to call an eiderdown- a forerunner of the continental quilt which topped a bed over the blankets.

That would make sense. Someone on LJ suggested it might be pillows too? I'm so curious!
