Chelkas Yaakov: Washing Neigel Vasser On The Top Bunk Bed
The Mishna Brura (1:2) writes that a person should wash “Neigel Vasser” immediately when he wakes up even before standing and should certainly not walk four amos before washing Neigel Vasser.  Later he says that some say that the entire house is considered within four amos but not to rely on this.  The Piskei Tshuvah says that even the leniency of the entire house means only the room he is in and not the entire house.

The Chelkas Yaakov asks whether height is considered when measuring four amos.  A common case would be a bunk bed that is elevated from the ground.  He answers that no matter how high the bed was it would still be considered within four Amos.  He compares this to the psak of the Maharsham who says that you can walk around the four amos surrounding you as much as you want no matter how many amos you actually walk since this is all within your four amos.  Similarly says the Chelkas Yaakov, no matter how many steps you must take to reach the ground from bed, since it is all within your four amos on the ground there is no problem.

Important Note: We try to convey the Tshuva to the best of our ability. We admit that our understanding may not be accurate. Please also understand that this Tshuva may not be the final word on this topic. One should consult a Rav before drawing any conclusions.
