Fits the Yeti Loadout 5-Gallon bucket perfectly. It has two separate grooves on the bottom: one for the loadout rim and the other for a regular 5G bucket rim. Ultimate compact camping toilet for heavy users. I could stand on it if I needed to; ultra-durable. I am going to cut it in half and hinge it so it can fold down for storage in the loadout bucket.

So comfortable you will wind up scrolling for hours, just chilling.
