I'm building a 30"x80" daybed with a simple rectangular structure for the frame. I plan to use 2x6 pine cut to length for the frame. Please do not try to talk me out of the pine, I already have it and know there are better wood options :) The boards on the frame will lay flat and be joined at the four intersections by glued and screwed half-laps. The slats between the boards will be Ikea slats cut to size.
Does my design seem sound? What's the best method for joining the slats to the frame? I plan to order steel legs online for the legs.
