Makes a perfect bed. No mattress or pillows required.
Better than a hammock, as it fits the body as pleasantly,
and lies _straight_. Folded or opened instantly. Self-fastening.
It is just the thing for hotels, offices, cottages, camp-meetings,
sportsmen, etc. Good for the lawn, piazza, or
"coolest place in the house." Splendid for invalids or children.
Sent on receipt of price, or C. O. D. For 50 CTS.
EXTRA, with order, I will prepay expressage to any railroad
station east of Mississippi River and north of Mason
and Dixon's line. For 75 CENTS, in Minnesota, Missouri,
and Iowa.
