A headrest for a seat assembly includes a central main body having a first side and a second side that is opposite from the first side. A first lateral stabilizer is moveably coupled to the first side of the central main body. The first lateral stabilizer is distinct from the central main body. A second lateral stabilizer is moveably coupled to the second side of the central main body. The second lateral stabilizer is distinct from the central main body. The first lateral stabilizer and the second lateral stabilizer are movable between retracted positions and stabilizing positions.

Described are headrest assemblies having at least one moveable member that is movable to reconfigure the headrest between: an opened arrangement in which a recess sized for receiving a ponytail or bun of hair is defined between portions of a head-receiving surface of the headrest; and a closed arrangement in which the recess is reduced or eliminated by edges of two members of the headrest being in abutment or adjacent to one another.

A removable privacy panel assembly (100) for a passenger seat includes a center panel (101) with a width approximately equal to a width of the passenger seat and at least one side panel (103, 104) with a connection to the center panel (101) where the at least one side panel extends approximately perpendicular to the center panel. The removable privacy panel assembly includes a deployed configuration where the removable privacy panel assembly is attached to the passenger seat and an uninstalled configuration where the removable privacy panel assembly is detached from the passenger seat. In the deployed configuration, the center panel is approximately aligned with a seatback (11) of the passenger seat and the at least one side panel (103, 104) extends forward from the center panel (101) beyond a seating surface of the passenger seat. In the deployed configuration, the at least one side panel (103, 104) is disposed adjacent to a headrest (15) of the passenger seat.

Sleep systems for aircraft are disclosed. An example sleep system includes a seat having a first headrest. A lateral sleep apparatus is positioned adjacent the seat. The lateral sleep apparatus includes a second headrest and a cradle coupled to the second headrest. The cradle includes a first attachment assembly and a second attachment assembly. The first attachment assembly is to couple the cradle to a support structure of a cabin of an aircraft and the second attachment assembly is to couple the cradle to the seat.

The technology described in this document can be embodied in a headrest of a seat, the headrest including an enclosure for housing one or more acoustic transducers, and an adjustable headrest wing disposed in front of the enclosure. The headrest wing is coupled to the enclosure by a pivot, and configured to be adjusted to one of multiple positions within an angle range around the pivot. The headrest wing is also configured to support the head of a seat-occupant. The headrest further includes a connector disposed between the enclosure and a rear portion of the headrest wing. The connector is configured to provide an acoustic channel between the enclosure and the headrest wing such that audio signals from the one or more acoustic transducers are radiated outward through the headrest wing.
