Synonym discussion
Sense: noun/1
All these words describe a spare or portable sleeping surface. A 'folding bed' is the most general term for any bed that folds into a compact shape for storage. 'Camp bed' (common in British English) specifically suggests a narrow, lightweight frame used for camping or as an emergency spare bed. 'Cot' is ambiguous: in British English it can mean a folding bed for a child or an adult, but in American English 'cot' refers only to a baby's crib. 'Rollaway bed' adds wheels for easy movement and is the standard term in hotels. 'Sofa bed' (or 'sofa sleeper') looks like a sofa during the day and opens into a full bed at night, unlike a folding bed which is stored away entirely. Example: 'The hotel sent up a rollaway bed for our daughter, while the campsite had basic camp beds.'

Etymology
The word 'folding bed' is a compound formed from 'folding' (the present participle of 'fold', from Old English 'fealdan', meaning 'to bend or double over') and 'bed' (from Old English 'bedd', meaning 'a sleeping place'). The compound came into use in the mid-19th century with the invention of collapsible metal bed frames designed for military campaigns and small homes.
