The most important thing is that your platformbe as close to level as it can get. You wouldn't believe the impact that a canted platform will have on you. Next is to have a big enough platform that you can stand without bending your legs around the seat. Another good one is that the stand be secure on the tree so there is zero movement, use an added ratchet strap if you need to, to cinch the stand. Top it off with a quality safety belt. The peace of mind of knowing you are strapped in will make you forget about falling, and shakyness or fear of falling is purely psychological.
