The "pool Noodles" I slit and put over the edge of the darkroom sink. Makes leaning over the sink painfree.
For that matter, adding a pipe rail/foot rest, at the typical hight and position of old fashioned standing brass bar rails, will be good for your back and comfort, as well.
Being able to stand in comfort for hours as you 'belly up' to a darkroom sink will certainly make the tasks of a long developing or printing session more 'doable' and, writing this, I have to wonder why I haven't done this myself, because it was in my original intent when I built the stand for my ABS sink, which already has rounded edges?
Pool noodles also can be stappled to door edges and around windows for light and wind proofing as well, especially when you need to pass an extension cord through a door opening or window.
This is how I kept an indoor extension cable providing power to my youngest's truck engine heater one very cold winter, no all that long ago, and light out of a carpeted hall/darkroom doorway, too.
