A simplified portable shelf *daisu 台子 set on the host's mat *temae datami 点前畳 in a tea ceremony room *chashitsu 茶室 to display tea utensils such as: a water jar *mizusashi 水指; ladle *hishaku 柄杓; lid stand *futaoki 蓋置; etc. The top and bottom boards of the daisu are often square, separated by either two posts shihōdana 四方棚, or four posts sumidana 隅棚.
However, other more complex styles exist, such as one with a board between the top and bottom boards, one with staggered shelves, or one with a drawer and raised shelf beside it called a *fukurodana 袋棚. A triple shelf type, kōshindana 江岑棚, made of paulownia wood with four posts designed by Sen Gensō 千原叟 (1664-1716) is about 44 cm high, and 32 cm square with a 10 cm high drawer at the top. Another type is made with an inlaid pattern of various kinds of wood and is called mikimachidana 三木町棚. There is also a small mulberry type shelf designed by Sen Joshinsai 千如心斎 (1706-1751). Such shelves were made according to the tastes of the tea masters. Only one type has round boards and is called marujoku 丸卓; joku means the same as *tana 棚 (shelf). The basic square shelf is about 43 cm high with the top board 45 cm x 42 cm and the bottom board about 37 cm x 40 cm. The posts or legs are 1.2 cm square.
