A Lilo is a rubber (or plastic) mattress you fill with air and use as a bed, or float on in a pool or the sea.

A Lilo是 is a rubber (or plastic) mattress you fill with air and use as a bed是一種你灌氣、當床用的橡膠（或塑膠）床墊, or float on in a pool or the sea或用來在泳池或海裡漂浮。

In British English especially, Lilo began as a brand (written Li-Lo, from the 1940s to the 1970s) and then became an ordinary word for that kind of air-bed — the way some people say a brand name for a whole type of thing. American English more often says air mattress.

In British English especially尤其在英式英語裡, Lilo一開始 began as a brand是一個品牌 (written Li-Lo拼作Li-Lo, from the 1940s to the 1970s從1940到1970年代) and then became an ordinary word for that kind of air-bed後來變成這種充氣床墊的通稱 — the way就像 some people say a brand name for a whole type of thing有些人會用一個牌子的名字來稱呼一整類東西一樣。American English美式英語 more often says air mattress比較常說air mattress。

Though actually in Taiwan almost nobody calls it a Lilo; they will look blank unless you say the Chinese for air mattress.

Though actually不過事實上 in Taiwan在台灣 almost nobody calls it a Lilo幾乎沒有人叫它Lilo; they他們 will look blank會一臉茫然 unless you say the Chinese for air mattress除非你說中文的「充氣床墊」。

The trademark was a catchy spelling of lie low, because you lie low on it. It has nothing to do with the girl in the cartoon Lilo & Stitch.

The trademark這個商標名 was a catchy spelling of lie low是lie low（躺低）這句話的順口拼法, because因為 you lie low on it你就是躺在上面。It它 has nothing to do with the girl in the cartoon Lilo & Stitch跟卡通《星際寶貝》裡的女孩莉蘿沒有關係。
