A multi-position sleeping structure includes a sheet material envelope defining a cavity with an opening. An inflatable mattress is received and substantially enclosed within the cavity of the sheet material envelope. A cover portion which, in conjunction with a top surface of the envelope, defines a sleeping area in which a person can lie and be supported by the mattress. The mattress has a plurality of transversely extending hinges that separate the mattress into a first portion, a second portion, and a third portion. The hinges allow the mattress to be moved between at least a substantially horizontal sleeping position and a seating position. The sheet material envelope has a retaining pouch to retain the mattress in the seating position. The retaining pouch is suitably sized and positioned to receive the mattress and sheet material envelope therein for storage purposes when the mattress is in the deflated storage condition.
