i use to work for Warren & Sweat Treestands. when we designed tree stands we would add steel weight to them while they were hanging until they broke or malfunctioned. once they broke, we would divide that weight in half and that would be the maximum recommended weight. i believe this is true for all treestand manufacturers. for example, if we had a stand with a maximum recommended weight of 300 pounds, we had 600 pounds of weight on it before it malfunctioned.

i am by no means telling you to use the treestand with the lightest recommended weight due to it being lighter to carry, just giving you a little insight. don't sweat being a few pounds over the limit.
