The types of furniture usually on display in Egyptology museums are largely from tombs of the elite. Some pieces may therefore be funerary items (such as the lion bed legs) rather than everyday objects. Although there are several pieces which are parts of furniture Egyptians had very little furniture in their homes. Chairs and beds would have only been used by the elite. Most people would have slept on a mat on the floor. Headrests would have been used by most people.
