passover seder hagada - Any practical tips for leaning when seated in an armless dining-room chair?

We are supposed to lean while drinking the 4 cups and eating the matza at the Seders, but I find it hard to do that while sitting in an armless dining room chair. Likewise, I have not been able to secure a pillow on such a chair. How do others deal with this little practical challenge? Any helpful tips would be appreciated. Note: there is another question Is there an ideal way to recline on Pesach? that asks what the ideal leaning posture is or might be. The current question just asks for practical approaches to leaning while seated around a dining room table.
