The NewsFeed recently released a picture of a proposed 23-inch pitch seat that resembles a saddle and which, so far, has driven interest from at least one U.S. airline, per the article.

I can already imagine the number of complaints this would generate…

But most importantly, is it safe? I mean… There already exist bracing positions for fore-facing and rear-facing seats, with or without shoulder straps… But what if you’re not even “sitting down” in the first place?

Any thoughts on this?
