I bought 2 convert-a-benches like the other reviews said. Took 30 minutes to put together the first one and 10 minutes for the second one. Not going to trust 3 adults on it, but 2 adults are fine as long as they don't bounce around. I wouldn't put more than 10 pounds on the table unless your sitting on the bench or you have the 2 put together, it will topple over if you don't. I don't know how long it will last being out in the CA sun. Only time will tell, or another reviewer who bought theirs years ago. Hinge part swings easily, it may last as long as the bench, unless the plastic pin that holds it together breaks. That is my only issue. And again only time will tell. Still I think it is a great investment.
