Several factors for comfort like seat design, seating posture, use of backrest, etc. This concept also adds privacy. The beds located along the aisle outside the main compartments (referred to as ‘side berths’) now offer more personal space, and are less claustrophobic. Middle berth passengers now do not have to depend on other passenger’s activity (e.g. If a passenger having food on the lower berth, the others will not have to wait till he/ she finishes).

The aisle is redesigned to reduce the impact of the obstruction to access caused by passengers standing against the draught screen. This also reduces the evacuation time during disaster.
