Europe's safety authority has certified to the 16g standard a new slimline seat design developed by UK manufacturer Pitch Aircraft Seating.
The certification for the PF3000 seat, and its compliance with head-injury criteria, enables it to be installed in high-density configurations.
Pitch Aircraft Seating says the installation is designed for single-aisle Airbus and Boeing jets.
It states that the PF3000 is a lightweight seat – below 25kg per triple-seat arrangement – which provides "the highest degree of comfort" at 28in pitch.
Developed from the PF2000, the seat has a fixed recline backrest with fewer parts than a standard reclining seat, it adds, offering "excellent serviceability".
