Kabbolas Shabbos-alternating recitation of Tehillim, seated?

In all of Europe Tehillim and Psukei Dezimroh (in the summer) were said Posuk Posuk (one by chazzan and one by the congregation), therefore the natural way to say the Pesukim in Kabbolas Shabbos (when people started saying Kabbolas Shabbos), was Posuk by Posuk.

Lately (before the war) this minhog was kept only in Ashkenaz and some Hungarian communities. Shir Hayichud is also said (by all who say out) in this way and melody.

Although you may not have to say the other part quietly (because you can be Youtzei from the chazzan), it is best not to have to rely on the chazzan, because you may not hear all he says. Of course this is more important in Psukei Dezimroh (where one should be saying all of Psukei Dezimroh) than in Kabbolas Shabbos (which is a late minhag).

In Mizmor Ledovid Hovu Lashem, Lecho Doudi and Mizmor Shir Leyoum Hashabbos one sits.

The Tehillim are said Posuk by Posuk, one by the Chazan, and the next by the congregation. The Chazan always says the first and the last Posuk. Since Hashem Moloch Togeil etc. has an even amount of Pesukim, the congregation says the last Posuk, therefore the chazan repeats it again after them, to finish the Peirek out loud.
