Then sand off the tips of the back brace things, like you said so they are as smooth as you can get it.

Then I would spray paint the chair, either the espresso or white, same as the table.

Now, I am not sure how much the back of the chair bows, so bear with me here.. I would go buy some 1/8″ (or less if available) thick press board, 1/2 thick foam and a little quilt batting and a really cool, funky fabric.

Then cut the wood to fit just inside the back of the chair, the foam to be the same size, wrap that with the batting and the awesome fabric front to back (just hot glue it in place). Then do a cover on the backJust flod over the edges and hot glue down and attach it to the back of the chair (you could sandwich two pieces together over the rails too…

Okay, well maybe that is good or bad idea, but you asked so hopefully it is something you haven’t heard yet.
