happy etin turkey all,
q is how best to design/build a catilever type seat??
want to incorporate a fireplace mantel ~ 20″ off floor, and about 15″ away from wall.
Thickness ?? Suggestions from the pros. But I want a shelf appearance. Or room for feet to come under seat. Figure to be 5′ in length and seat about 2 people (max).
Please help!! I’m really looking for structual tips and framing tips to support 2 people.

angle iron brackets, welded in an "L", one leg through-bolted to the studs, other leg inside or under seat/shelf.
tortion box.
No supports needed and you can park a car on top of it.
I can explain briefly what it is but you may have to look it up to get full details.
Essentially it is a gridwork of 1x material glued to two skins and bolted through to a wall's studs. The way the webbing/gridwork is glued to the skin gives it extraordinary strength.

I did this one all out of framing material. The cantilevers are ripped from 1-3/4" LVL's sistered together, like a plywood 4x4. Extremely stiff. Each cantilever has a post under it behind the drywall so it can't sag. At the back end of the cantilevers, behind the firebox, they have a block above the tail, glued to the stud on that rear wall. Sub-deck is 3/4 ply under the wonderboard. Glue everything to everything else with urethane glue. I'm 230 disgusting pounds, and I can stand on this without the grout lines cracking.
Any bracket fastened solely to the single wall plane at the face of the firebox will not have the lever arm it needs to resist moving; I don't care if it's made of titanium and fastened with grade 8 bolts.
You might consider not going higher than standard chair height, like 16-17 inches, for you hearth. People are gonna sit on it at some time; make it a comfortable height.
