I call them sleeper seats. Agreed, unless you have deep pockets or a pal with an industrial machineDo you really want to build them from scratch?
You can buy lounge seats or back to back seats, what ever you want to call them.
That’s a sharp boat!These are the type of boat seats that I want to build from scratch. I have a 1960 something Star Craft boat.I want to fix what the idiot took out. I know that they were back to back seats, that folded out flat. To make a bench seat. Like these,(see pics).View attachment 339288
