Sitting in the Succah

Hi,

One fulfills the mitzvah of sitting in the succah only if one is sitting directly beneath the schach roof material.

Therefore, one should make sure not to sit under decorations which are more than 1 square foot in area and hang more than a foot down from the schach.

Also, one who is sleeping in the succah should not sleep beneath a table, for the same reason.

(Shulchan Aruch Orach Chaim 627)

Have a great day,
Mordechai
