In Deep Sleep Modes the strap attaches to a frame which is insideof the pillows. When the user leans into the pillows they connect with their chest and face/head. If the user is pushed forward quickly (for any reason), they are retained by their plane's seatbelt primarily but the pillows act as a protective device to support the head and body.
If extreme force is applied to the straps, they are designed to separate from the frame. The straps do not connect around a person’s neck and are considered no more dangerous than a carry-on bag with shoulder straps. FaceCradle has been used on many flights to date with no issues from airlines.
FaceCradle was shortlisted for an airline industry passenger comfort award.
It is important to note that your seatbelt is your primary safety device that will hold you in your seat during any turbulence or sudden movement so it should be worn at all times when using FaceCradle.
