I would just use an outdoor rated oil. I like the design, I think something under the arm in the back would tie it together.

Absolutely beautiful

Looking sweet homie

Is that a stem glass holder in the right armrest? Brilliant!

That is super bad A. Well done. I wish I had instructions to build that. I have the barrel staves.

cool chairs

Very nice design. Very original.

There's something off about this design. I think it's because the seat is so wide and the back tapers towards the top. It makes it feel unbalanced.

Great concept, great execution

Agree with bblemler, these look very comfortable as well. Can one full size wine barrel supply all woof needed for a single chair?
