Sukkah 19b

AI summary (may contain mistakes)

When does a reed mat become mekabel tumah and so pasul as schach? Peshutei klei etz, flat wooden items with no receptacle, take no tumah unless designated for lying or sitting, which brings tumas medras. A mat made for sleeping, even by a non-Jewish manufacturer, takes tumah and is pasul as schach, while one made for schach is kosher. Normally a large mat is made for schach and a person-sized one for sleeping.

Key points

• Flat wooden items take tumah only once designated for sitting or lying, bringing tumas medras.
• A mat made for sleeping, even by a non-Jewish manufacturer, takes tumah and is pasul as schach.
• Normally a large mat is made for schach, and a person-sized one for sleeping.
