We are not pleased with this chair.  It is a 40" wide chair on a base that is 1 2" wide.  When you go to stand up the chair tips to the side.  The other day my Aunt fell while trying to get up out of it. We asked for help & you took over 30 days sending wedges that do not stabilize it. Now what do we do?  We still have the same problem and no solution.  Please advise.
