The Middle Seat

1. Seat width
2. Seat position
   • Position (backward)
   • Height
3. Wing passenger movement

1. Seat width – going by the video, actual seat width has not increased, but only the seat (stretching under the armrest) and backrest are wider. This would undoubtedly be more comfortable than the present seats. However, the armrests would still press into the stomach region of an obese passenger. Fixing this would need a seat redesign, as it would be tough to widen the gap between armrests without narrowing the passage area
2. Seat position
   • Position (backward) – Purely from a position perspective, the MLS design is an improvement. Ordinarily, middle-seat passengers perhaps have even less privacy than others (ever been in the middle seat looking into your phone, and realized your co-passengers were too? :P). With the centre seat slightly behind, its passenger would at least get some privacy for suffering the seat.
     My bigger concern: The back of any person, is not a flat plane. It curves slightly at the shoulders, more if the person hunches. In the current design, an obese person’s shoulders might extend into the backrests of seats on either side, whether they are all in upright or reclined position. With the new offset layout, it would be very restrictive (and for some, claustrophobic even) as it obstructs at arguably a person’s widest cross-section.
   • Height – If the obese passenger is short (maybe under 5’3″, the lower new seat position works fine. But for an average to tall passenger, it is a transition from uncomfortable, narrow seats; to uncomfortable, narrow and low seats – which means not only might their back hurt afterwards, but also their thighs and calves
3. Wing passenger movement – currently, the wing seat passenger moves straight in and out. With the MLS redesign, they would have to zigzag their way in and out (and for loo visits) – a partial inconvenience

1. Seat width – the new MLS wide seat design, which seems marginally more comfortable. However, only a complete redesign allowing for wider gaps between armrests would actually make it better for the passenger
2. Seat position
   1. Position (backward) – 3 seats slightly offset from the other, forming an “A” layout (if you consider all 6 seats, three on either side of the aisle in a given row, they would form an A pattern, with the aisle seats forward, and the wing seats further behind for the same row). Seemingly more uniform level of privacy irrespective of seat. And each passenger has zero obstruction of adjoining seat backrest or passenger on one side
   2. Height – all seats of same height to prevent added leg/thigh and lower back fatigue for middle-seat passengers
3. Wing passenger movement – currently, passengers need to turn 90° into or out of their row. In the suggested layout, while visits too the loo would involve a bigger angle of turn, but only boarding and disembarking would be at only a slight angle from the aisle.

Thoughts?
@MLS, like you, I am simply looking at it from trying to improve passenger experience. Hope you find this useful.

On the topic of airline seats, here’s an old thought I had.

The Middle Seat analysis was part of an initiative called RattL ’em.
What is RattL ’em?: We are constantly fascinated by companies, products and services.
So, every few days, we send out an email to, or share an idea online about a random company anywhere in the world that caught our fancy. The email either contains an idea for a new product or service, a concern area to focus on, or a new feature or improvement to their portfolio.
We do it for free. And for fun. And the company that receives it is free to use the idea, with no financial or other obligation toward us. We think of it as our way to be the best at what we do in the field of innovation and design strategy consulting.
