I photograph Custom made pool cues .
Reflection is the main issue, trying to get past the finish and see the wood grain is a challenge.
I use either a TSE 17mm or TSE 24mm lens, I assume you have a hard time getting all of the furniture in one frame and still be able to see the wood grain or figure
I would like to suggest reading a book called Light Science and Magic.
there is a section of this book that covers photographing furniture with a glossy finish.
I want you to key in on page 65 and up, it covers a technic called
( cross polarization ) which I think will help you improve your product photography.
Problem with Cross polarization is the size of your soft box, Linear polarized film is only 17 inches wide so either you tape the film together and stretch it over your larger soft boxes or you buy the narrow 10 x 36 in soft boxes.
You use the linear polarized film over the soft boxes and a CPL on your lens.
Please note if you try to defuse the light after it passes through the linear filter you once again create polarized reflection.
