Italian airline designs stand-up airplane seats

Who hasn't complained about leg room when they fly? Is it possible for a flight to be even more cramped with stand-up seats?

The seats are called Skyrider 3.0 and are designed by an Italian airline.

The seats look similar to a bicycle seat but with back support.

The manufacturer says the goal is to give passengers more options. They call it "ultra-basic economy."

So far, there isn't a lot of interest. The seats don't fit specifications for some common passenger jets.
