Rivers Edge and Gorrilas have large platform stands that go up to 300lbs or more, cant remember. They both will only cost you about $100 for the top end, and $79 for the low end. I have friends of mine that i played college ball with and some other guys i just know who were O line men, 300lbs + sitting in those stands. You should be fine, if your worried add another tie down to them for extra support.
