I used a Crazy Creek style for years (lightweight no longer made Osprey, it was great but it finally wore out). Several friends use Crazy Creek's. Hillsound stools work well and there are many fans of them out here. I have one too and it works great but it's mostly used at the truck. I have gone back to basics (light) and just use a pad to sit on. Not glassing but early CO elk I pack a Helinox. The only place the Helinox works glassing is flat/flatish ground with my big tripod that can straddle the chair.
