Remember, the "bench" needs to be rigid/stable. This means heavy or deep or bolted to the wall (or floor).
Being in the bedroom (not sure if that is GOOD or BAD with the wife...
) but I am assuming space is limited. I have a design where you use your body weight as dead weight to stablize the bench. I built and use one when I had to reload on the back concrete porch, and continued to use it when I moved into my own house. Long retired since I built a custom bench that is bolted to the wall.
If you want, I can sketch the plans and post them here.......
