I completed this project today and took a nap on it before I even put my
tools away. :-)
It's built from cedar 2 x 4's and 1 x 4's and finished with Rubio Monocoat.
I used their Hybrid Wood Protector. 2 parts Pure and 1 part Royal. The Pure
has no UV protection, but they told me that 1/3 of any pigment is all that
you need.
I built it as 2 separate pieces for ease of movement. Once piece has 2
armrests and can function as a standalone sofa. The other is more a
day-bed type piece, although the open end legs can be removed and
replaced with an armrest. It would then be an exact match for the other
piece.

Now I have to refinish the deck. I better order more Monocoat. :-)
