Our main interest on this forum seems to be Domestic Discipline, especially WHASS (wholesome home and school spanking) applied to minors. To that extent, the furniture which most of us use, imagine, or write about probably tends to be limited to those things found around a home or school - straight backed, armless chairs for a parent to sit in, while taking a boy across their lap; a bed (especially a child's bed); a footstool; a couch; easy chair; a kitchen table and chair; or a student's school desk or a more regular desk.
HOWEVER, other options are available. While I find it hard to imagine most parents having furniture specifically used to spank (unless they have a kink of their own, I suppose), there are things you can find around the house. I know sawhorses can be used for various standing/bent over positions, especially with just a bit of added padding, but then I see something like this...

While this is made as one object, it's basically just a stool and table next to each other. Without the hooks for restraints, it's easy to imagine having these items in the home... and it wouldn't be hard to use them with restraints, if it was called for.
If you've ever watched a video from Spanking Central (RIP, Cliff) or Spanking Straight Boys (amongst many others) you know there are a variety of spanking benches, stocks, and hoists available specifically.
So, what I'm wondering is pretty much threefold (or even fourfold) - can you think of other furniture that's used for spanking on a quotidian basis, what else that's common in a home could be adapted for specific spanking use, can you see situations (outside of very strict schools) to use more specific furniture for spanking minors, and what is your favorite furniture for spanking (as a top or bottom)?
