Wondering about some solutions for moving a big cushioned bench (think outdoor furniture-type sofa, metal frame). It's a bit heavy for dragging around in scene changes, so having it on wheels would speed things up and be safer. However, it just has four big metal legs. I could put it on a wagon of some type, but then it would be at an uncomfortable sitting height to the floor (and a bit of platform sticking out the front to trip over wouldn't be ideal either to solve that). I've considered maybe some type of platform with holes where the legs somehow sit on a flat piece of metal hardware attached to the bottom of the platform (inside the holes) so the wheels can be inset under the platform and very little height is added, but it seems like this would be easy to do in a not so structurally sound way (if not done very carefully), particularly if the holes are at the edges. I did consider little three-wheel moving casters, like the attached (under the legs), but I can only find them rated for a pretty small load and since they'd still be there when three people sit on the bench, it doesn't seem ideal from a safety perspective (and the bench is heavy-ish too). (Oh, and of course, this type of solution doesn't lend itself to safely braking the unit while it is in use...) Thoughts? (And no, we don't have access to welding equipment.)
