Double-Decker Airplane Seat Prototype Draws Mixed Passenger Reactions

A prototype for double-decker airplane seats aims to increase legroom for economy passengers without requiring additional aircraft space. The concept, known as Chaise Longue, was developed by a Spanish designer in 2020 during postgraduate studies. It features a two-tiered layout that removes overhead bins to allow stacking of rows, providing more space for lower-level passengers.

The design offers approximately six feet of pitch and 12 inches of recline on the upper level, which is 50% more than typical premium economy cabins. The lower level includes a similar pitch, recline, and a sliding footrest for leg extension. Footwells in the seats provide storage space, compensating for the lack of overhead bins.

Updates at Recent Expo The latest version of the prototype was presented at the Aircraft Interiors Expo in Hamburg.

Improvements include enhanced privacy barriers between seats, greater separation between levels, and modifications to the front row for passengers with reduced mobility. Access to the upper deck is via stairs with a 25 cm tread depth to facilitate entry, exit, and emergency evacuations. Passenger reactions to the concept have been mixed.

Some travelers expressed concerns about the enclosed feel of the seats, comparing them to coffins and worrying about emergency egress, particularly for older individuals. Others noted potential issues with odors from the upper level affecting those below. One passenger highlighted the appeal of extra legroom for taller people but discomfort with someone seated directly above.

Another supported the design if integrated into economy class, viewing it as a benefit despite not being available for the lowest fares.

Airline Interest and Challenges The concept has attracted interest from major global airlines.

Airbus has been mentioned among those showing preliminary engagement. No commitments have been made due to the time and cost of retrofitting aircraft, along with the need for safety approvals. Implementation of such designs requires extensive testing and regulatory clearance, which could delay widespread adoption.

The designer has indicated plans for a more budget-friendly version in the future. This prototype represents ongoing efforts in the aviation industry to optimize cabin space amid rising demand for affordable comfort.
