Halocho #1393 - Can we sit on chairs on 9 B'Av?

On the fast of 9 B'Av it is customary not to sit on chairs from the time the fast begins (Monday afternoon before sunset) until noon the following day (Tuesday).

Instead, one sits on the floor. Anything within 3 Tefachim (about 9" - 24 cm) of the floor is considered as being on the floor.

After noon on 9 B'Av (Tuesday) one may sit on regular chairs. However, all other restrictions of the fast apply until the fast is over at night-fall.
