TV Tray from Walmart for Ashford 24” Rigid Heddle Loom. The TV tray is 26” wide and has several height adjustments. I think it cost < $15.
The Ashford 24” loom is actually about 28” wide so it does overlap about 1” on each side. I needed to use a board with the loom clamps on the back part of the loom since the TV Tray table didn’t have enough depth for the clamps.
It’s working very well and is very comfortable.

NOTE: My Walmart sold them individually so that is how I bought mine.
