What has one head, one foot and four legs?

“A table”

A table typically has four legs, but it does not have a head or a foot, as it is not designed to support a person lying down.

“A chair”

A chair usually has four legs and can have a backrest (considered its 'head'), but it does not have a foot in the context of this riddle.

“A sofa”

While a sofa may have a 'head' in the form of a backrest and four legs, it does not typically have a defined 'foot' like a bed does.
