Do candle sticks, flower vases, and other ornaments positioned in the Sukkah to beautify it become prohibited in benefit?
Some Poskim[1] rule that that all items placed in the Sukkah for the sake of beautifying it are forbidden in benefit [unless a stipulation was made] even if they simply are resting on a table and are not actually hanging in the Sukkah. Other Poskim[2] however rule that it does not become prohibited in benefit unless it is attached to the walls or Sechach.

[2] Chelkas Yaakov 2:127; See Piskeiy Teshuvos 638 footnote 13; In Admur, no mention is ever made of the possibility of even items resting on a table becoming Noiy Sukkah, and in all areas mentioned, Admur refers to hanging decorations. [See Admur 638:6 and 11]
