A thought on reclining at the seder:
This is not my own, the idea is well known, but important.
Many of us today, including me, lean to the left in our dining room chair, with or without a pillow or cushion, and call that heseiba. Clearly, this is very different than the proper performance of the mitzvah. In the olden days, people sat closer to the floor, on some sort of stuffed couch or fouton, in a relaxed position, similar to what may be seen in certain oriental restaurants, or so I’ve heard.I admit that the way I do it is rather uncomfortable, artificial, and incompatible with the purpose of heseibah, but I do it because that’s the way I grew up.
I do know of a rosh yeshiva who leaves his dining room, goes to his living room (salon in Israel) , spreads himself out, and does true heseibah there, including maggid and the parts where heseibah is a halachic imperative.
