Size of cleats for bench?
I am building a window seat bench, dimensions 60"w x 18"d x 1.5"thick, using poplar (will be painted).
I want the space underneath the bench to be open, so there won't be any legs to support the bench. Instead, I want to use 3 "shelf" cleats, one on each of the three walls of the niche.
My questions are:
1. What size cleat should I use? 1x2? 2x2?
2. Do you think the cleats are sufficient to hold up the bench and any persons sitting on it?
3. Any suggestions on how to attach the cleats to the walls? Two of the walls are sheetrocked with regular framing behind them, studs spaced 16". But one of the "walls" of the niche is actually a built-in cabinet. The cabinet "wall" is approx. 1" thick.
4. Any suggestions on how to attach the bench to the cleats besides just placing it on top of the cleats?
Thanks in advance for any advice you can offer!
