Quaderna side-table / stool  

mike45,
This is too easy.
Establish an intelligent retail price you are willing to pay. Contact one or more of the trusted sellers in the "buy & sell" area of this site and offer a "premium" (cash) for them to locate your piece. They like others may be motivated by money (promises and desires are worthless). You may know this as "money talks and bullshit walks"*.
I wish you the best with your search.
*this colloquialism is not a reflection upon you and should not be considered as such (in particular by those who worship items)

mike45,
I failed to look on-line and see all the Zanotta Quaderna products for sale prior to my original posting (no side tables). Having now done so, I would contact "all" the authorized sellers (no after market dealers) of the Zanotta Quaderna product line and inquire as to "remaining inventory" of the side table you desire.
Should you not get the desired outcome proceed to cash incentive to trusted after market dealers.
Patience and cash liquidity are both virtues. Best of luck.
