Engineering firm ADSE has introduced the Economy Sky Dream, a new long-haul economy class sleeping solution.

The innovative cabin design from ADSE creates a new economy comfort class that is aimed at wide-body aircraft such as the Airbus A350 and Boeing 787 and 777 and which focus on elements such as passenger comfort, airline operations, cost of ownership and airworthiness.

Passenger comfort is increased by delivering an improved sleeping experience and extra-wide seats. A full-lie flat experience is created through a bunk-bed concept. The design makes optimal use of the height in the middle of the aircraft; the central overhead luggage bins are taken away to create vertical space for a three-person full lie-flat bunk bed.

During taxi, take-off, cabin service and landing passengers of two rows will be seated opposite to each other in club seating configuration, with their hand luggage stowed under the extra-wide seats. The middle bed will easily move down during the long cruise to make room for three equally spaced beds in bunk bed configuration.

The beds are 76-80-inch-long beds, depending on the aircraft, and have a width of 23.6 inches,  20 per cent wider than a regular economy seat, giving enough space for a comfortable sleep.

Moreover, airlines will not have to compromise on revenues as the Economy Sky Dream has a passenger density similar to a regular economy comfort class. Additionally, the increased passenger comfort provides an increased revenue potential. The current operational and evacuation procedures fit within the design space, meaning that the impact on these procedures is minimised.

The only additional operational support that may be required is when converting to bed configuration or vice-versa. Based on an operational procedure set by the airline, or a joint arrangement by the passengers that sit on the same bunk bed, the moment of seat-to-bed conversion can be determined.

The business case for the new product is based on a technically acceptable investment risk, by opting for a modular concept that allows for easy installation and retrofit into wide-body aircraft. It can be built into the existing seat tracks and luggage rack suspension, which makes the system relatively quick to build in and out using existing installation techniques. The residual value of the aircraft will also remain unaffected.

Although novel in nature, ADSE says the concept can “meet the latest airworthiness requirements to fit the broadest range of new aircraft and will have a non-significant effect on the certification base of the aircraft.”
