Duh---NOW I finally get what you are asking to do..(I was sick last week and I will use that as an excuse!!)
The plywood is 3/4 inch and the leg looks like the same ones that is used on the larger dinette (bed) I presume Reace just cut it to size for where we want to use it...
I can see now what you want to do--make a bunk bed area in the front
?? 4 legs-- 1 for each corner and it would just sit on the two benches.... Would it stay "up" all the time....And would it have another way of "securing" it--to the wall or wardrobe??
