Prayer Chairs
Prayer chairs are on trolleys in the walk ways inside the Haram. If you don't see any you could ask the workers in the area and they will gladly oblige. A small tip would be in order. Another option would be to buy one - it cost 25 Riyals and one could take it around to use when needed. At the end of the trip you can leave it in the Haram for others to use Always check the chair before you sit as sometimes the are damaged and one could get hurt.
