A cupboard that is full of vessels and one affixed a covering to it is impure. [If] it was empty and one affixed a covering to it, it is pure. To what is this similar? To empty jugs, which are filled with wind, which is pure. A cupboard that possesses corpse-impurity and he affixed a treading-place to it is completely pure of all impurity, but it is susceptible to impurity from that point forward. A cupboard that is half-open and half-closed imparts midras-impurity and possesses corpse-impurity. [If] the top of it was cut off, it is is impure because the lower portion acts as a receptacle. [If] the bottom of it was cut off, Rabbi Meir renders it impure and the Sages render it pure, because once the primary purpose ceases, the secondary purpose ceases. A goatskin pouch that was cut open*, behold, it is impure, for from the beginning it was used for sitting and for laying upon along with its function [of holding liquids], and now it is [still] used for sitting and for lying upon, the words of Rabbi Meir. And the Sages render it pure* because once the primary purpose ceases, the secondary purpose ceases. The Sages agree with Rabbi Meir that regarding a leather bolster or cushion that was torn, that even though it can [no longer] hold that which was inside it (i.e., the stuffing), that it is impure, and needless to say, as to bolsters of fabric or sackcloth (GR"A), it is not that they are impure on account of having a receptacle; rather, on account on their fabric (Kel. 20:1). Rabbi Yosei says, the cupboard of the bath attendants that is higher than ten handbreadths and has a rim is impure, for from the beginning it was made for the purpose of ascending and sitting on top of it.

A cupboard from which they sell oil in a public bath possesses corpse-impurity and midras-impurity. [If] one brought a beam and affixed it from rim to rim in order to be able to sit on it, it is impure, but it only defiles one who uses it for that purpose. Four planks that are [affixed] on four rims: [If] their width was a handbreadth they are impure. The upper board upon which they pile up coins: Even if it has a pure rim, [if] they brought another plank and affixed it to the rim to be able to sit on it, it is impure, but it only defiles one who uses it for that purpose. A tailor's shelf: [If] it has sides, it is impure, [and if] it does not have sides, it is pure. [If] he brought a beam and affixed it from rim to rim to be able to sit on it, it possesses midras-impurity, but it only defiles one who uses it for that purpose. The tables of large cities that are eaten upon, even though they are affixed with a nail, they are impure. [If] he brought a chair and affixed it to [the table] from rim to rim to be able to sit on it, it is impure, but it only defiles one who uses it for that purpose. Chairs that are on a stand, behold, they are pure, for they were only made to be used with (i.e., when attached to) the ground. And the stocks [of prisoners]* are pure, for they are nothing but seats of suffering.
