It well could be Roche Bobois.
I have a few of their case goods (but not this piece..or pieces), and the company doesn't put a makers mark on anything. Occasionally a faint ink stamp saying "Made in Italy" will appear...even the they are a French manufacturer. Now the upholstered pieces that I own have a Roche Bobois printed fabric on the decking and underside..
Best,
Aunt Mark
ps Highly under-rated pieces.
