Following other proposals for standing "seats" on airplanes (link and link), the Skyrider 2.0 saddle seat "is the new frontier of low-cost tickets," according to Italian company Aviointeriors. Rather than pitch the Skyrider as an inexpensive option for fliers, I think they'd do better positioning it as a healthy luxury like standing desks. From the Boston Globe:
For airlines that have been trying to shed weight and save on fuel costs by introducing thinner seats and eliminating seatback screens, the Skyrider 2.0 makes perfect sense. According to Aviointeriors, the design allows a 20 percent increase in passengers per flight. It also weighs 50 percent less than a standard economy seat, lowering the fuel cost per passenger…
The reduced legroom brings the seat pitch (the distance between one seat and the next in front) down to 23 inches. By way of comparison, the seats on low-cost, low-rated Spirit have a seat pitch of 28 inches.
