I don't know the reason why this person created these chairs. However, I have a feeling people may be looking at it too literally.

Yep, sexual politics. Since you brought it up, I'll wade right in.

Look at those 2 photos, showing the traditional male and female positions reversed.

Which person looks relaxed, comfortable, body held in a natural posture, and ready to interact with the world?

Which one looks tense, uptight, controlled, and drawn in on themselves, with the body held in an artificially closed-in posture? (Prim and proper, one might say.)

For those who will say, "darn right he's uncomfortable, his balls are getting smashed", do you think the body posture in that photo is a happy one for women because their bodies don't include testicles? That's pretty much the way women are taught to sit all the time. Legs together, posture prim and proper, always thinking about how we look.

Human beings have always made up a lot of odd rules for living, haven't they? And ostracized those who don't comply.

My mother wore a girdle during her entire adult life. That's the way her generation did things, in order to "keep things under control" and make themselves look attractive.

When I was a teenager, she tried to make me wear one. That lasted about a day. Good god, what a torture contraption.

Not as bad as the 15 pounds of undergarments, including bustles and tight corsets, that women in Victorian times had to wear, though. Try sitting in that get-up. Or walking. Or even just breathing.

on a Harrow-on-the-Hill to Amersham Metropolitan 'tube' train at 10 at night (i.e., few passengers; lots of space), but well nigh impossible going into London during rush hour/working hours (see, No Space).

Up until very recent days indeed, Cardinals entering into Conclave to elect a Pope would have to sit in a chair possessing an opening exposing the genitals, while a Cardinal from each of the three Orders (Cardinal Deacons, Cardinal Priests, Cardinal Bishops) would observe and proclaim: "testiculos habet et bene pendentes" (i.e., "he hath testicles and they hang well") before they would be permitted to enter Conclave. This was in response to the various "Pope Joan" scandals.

It is my understanding that this requirement wasn't finally removed from the books until the Conclave regulations promulgated by Pope Paul VI (reigned 1963 - 1978)!

And the chair? It was a birthing chair from Byzantine Greece!

to coexist. Right now all behavior is acceptable in the name of self expression. Confrontation breeds heroes and villains. Social media amplifies opposing points and builds flash movements. Legitimacy is gained through alliances of victims. So the same mentality that brought chastity belts into existence brings you specially designed chairs and is presented to us as a solution. Meanwhile it's us that fiddle as Rome burns.
