Reply To: Using Beach Chairs in Shul on Tisha B’Av

I saw this last year for the first time and thought it inappropriate.
I also grew up in a shul where we sat on faux wood grain cardboard boxes that the funeral directors use to provide for those in aveilus.
In the shul I attended yesterday the long cushions were removed from the pews and placed along the walls. I sat on the 3” high cushion with my back against the wall for support.
The only one who brought in a low beach chair was the 80 year old Rav, he explained that he needed the arms on the chair in order to be able to get up at chatzos.
