I've not used this one, but I do use the TreeSuit which is a similar product. I hunt private property and have "permanent" stands placed but the TreeSuit is great if you need to move discreetly and fast. I also take it along with me (as my only stand) on out of state trips. I've never had a problem sitting for extended periods.
