      n : a room used primarily for sleeping [syn: bedroom, sleeping
          room, chamber]
 Bed-chamber
    an apartment in Eastern houses, furnished with a slightly
    elevated platform at the upper end and sometimes along the
    sides, on which were laid mattresses. This was the general
    arrangement of the public sleeping-room for the males of the
    family and for guests, but there were usually besides distinct
    bed-chambers of a more private character (2 Kings 4:10; Ex. 8:3;
    2 Kings 6:12). In 2 Kings 11:2 this word denotes, as in the
    margin of the Revised Version, a store-room in which mattresses
    were kept.
