accubitalia

Of Ancient Roman furniture, accubita was the name of couches used in the time of the Roman emperors, instead of the triclinium, for reclining upon at meals. The mattresses and feather-beds were softer and higher, and the supports (fulcra) of them lower in proportion, than in the triclinium. The clothes and pillows spread over them were called accubitalia.
