<注釋>The history of the wordmattress is a small lesson in the way amenities have come to Europe from the Middle East. During the earlier part of the Middle Ages,Arabic culture was more advanced than that of Europe.One of the amenities of life enjoyed by the Arabs was sleeping on cushions thrown on the floor.Derived from the Arabic wordúaraôa, .to throw,. the word maúraô meant .place where something is thrown. and .mat, cushion..This kind of sleeping surface was adopted by the Europeans during the Crusades,and the Arabic word was taken into Italian (materasso ) and then into Old French ( materas ), from which comes the Middle English wordmateras , first recorded in a work written around 300. The Arabic word also became Medieval Latinmatracium, another source of our word.
mattress 這個詞的由來是康樂設施從中東傳到英國的一個小小見證。 中世紀早期，阿拉伯人的文化要比歐洲文化進步。阿拉伯人生活中享受的一個康樂設施就是睡在鋪在地上的墊子上。由阿拉伯語中的詞taraha .扔.派生出來的詞 matrah ， 意思是.鋪著東西的地方.和.墊子，沙發.。這種睡覺方式被十字軍東征時期的歐洲人採用，這個阿拉伯詞因此進入義大利語(materasso )和古法文( materas )。 從這兩個詞又引出最早出現於300年左右的一部著作中的中古英文辭彙materas 。 這個阿拉伯詞同時也被收入中世紀拉丁語，即matracium ， 這也是我們這個單詞的另一個來源
