Cubiculum were mainly used as bedrooms at night. During the day, they served as rooms for private meetings with clients by the paterfamilias or head of the household, the reception of an intimate friend, a library and for conducting highly confidential business. As a bedroom, they would have contained a sleeping couch or two, a small storage chest and a dressing table.

The matrona or older married Roman woman would have kept her personal toilet items on the dressing table. Some of the items probably included a mirror made of polished bronze, copper, silver or glass with a lead backing, various combs, hairpins, etc. The dressing table would have also held the many cosmetics in a variety of vessels, jars, bottles or small boxes made of bronze, gold, silver, alabaster or glass.
