Assalamu aleikum wa rahmatullah wa barakatuhu. ref: Fatwa No : 142461 Where to place the chair in the row when praying sitting Fatwa Date : Thul-Qi'dah 30, 1431 / 7-11-2010 You write that: The second type: the one who prays standing but he will sit when bowing down and when prostrating. We have not come across any statement of the former jurists may Allaah have mercy upon them about the position of the praying person in such a case; however, Shaykh Abdur-Rahmaan Al-Barraak was asked about this and he said: "What should be taken into account here is the standing position, so he should be level with the row when standing. In this case, the chair will be behind the row, and it should be placed in such a manner that does not disturb the praying people in the row behind." === How is the chair placed in such a manner that does not disturb the praying people in the row behind? JazakAllahair. Wasalam, Umar

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

It is known that the distance between the rows is not the same in all mosques; some rows may be close to each other and some may be farther away. The chair may be placed in the manner described in the question if the distance between the row including the chair and the row behind it is enough for the worshipper (in the row behind) to prostrate himself without causing him any inconvenience. The chair may also be placed at the end of the row.
