A removable and adjustable headrest capable of being manually installed without the assistance of a tool and which is adjustable about at least one axis is presented herein. The headrest includes a headrest frame, an adjustable clamping mechanism, an adjustable neck mechanism, a rocking arm assembly connected between the headrest frame and the adjustable neck mechanism, and at least one activation lever. The activation lever being connected to the headrest frame and being manually disposable between a normal position and an activated position. When the activation lever is held in the activated position, a gear assembly is disengaged, allowing the headrest to be manually tilted about an axis.

A pillow has a supporting structure and a cushion. The supporting structure is made of composite materials and is pre-stressed and resiliently bended. The cushion is resilient and covers the supporting structure. With the supporting structure and the cushion, the pillow provides two-stage resilient support. When a user rests his head on the pillow, the cushion is compressed easily at first, and then the supporting structure being resiliently bended provides sufficient support to the cervical spine of the user, making the cervical spine of the user rest in natural relaxation when the user rests on the pillow.

Generally, a face hammock, and a method of making and using a face hammock to support the head of an individual. Embodiments can include a first support member disposed in opposed spaced apart relation to a second support member and one or more flexible members connected by the respective flexible member ends to the first support member and the second support member can be positioned to supportingly engage the head of an individual.

A device for audio reproduction comprising a rest element for the head of a user, made of a deformable material; a right lateral support element and a left lateral support element located respectively at the two respective right and left of the rest element, the rest and left lateral support elements being connected to each other by the rest element, the right and left support elements defining between each other a listening space and a longitudinal direction parallel to the lateral support elements; a right loudspeaker and a left loudspeaker mounted respectively to the right and left lateral support elements have respective sound emission faces that face towards a listening space defined between the right and left support elements. The rest element provides a housing for a portion of the head configured to arrange the user with right and left ears oriented towards the right and left loudspeakers, the right and left ears creating a listening axis. The loudspeakers have each a woofer and a tweeter, the tweeters having an axis of symmetry oriented with a predetermined angle of elevation (α) with respect to the listening axis between a first elevation value (α) substantially equal to zero, where the tweeters have the axes of symmetry aligned to each other and parallel to the listening axis, and a second elevation value (α), substantially equal to 45°, where the tweeters have the axes of symmetry converging towards a point that is located higher than the listening axis. A system of binaural recording and a system for playing multi-dimensional effects are also included.

In one aspect, embodiments of the present disclosure relate to a convertible cushion system including a pillow portion configured to detachably couple with a retaining portion in an assembled state. The pillow portion generally includes a base pillow portion configured to releasably attach to a portion of the retaining portion; and the retaining portion includes a retaining cushion having first and second opposed ends and at least first and second opposed faces, at least one adjustable strap having first and second opposed ends, the at least one adjustable strap disposed on the first face of the retaining cushion and configured to secure the retaining cushion around a user, and a connecting mechanism for detachably connecting portions of the at least one adjustable strap to create a loop. Also provided herein are methods for making and using the disclosed devices and systems.

A fully adjustable privacy/protective headrest with foldable protective wings for use in connection with furniture and with passenger vehicles such as aircraft, trains, and buses.

A headrest device includes a headrest support and an adjusting seat. The headrest support is a flat rod and has a ditch and a bias rack beside the ditch. The adjusting seat is being inserted by the headrest support and has a pressing member and a buffer assembly. The pressing member is elastically pivotedly connected into a side of the adjusting seat. Part of the pressing member protrudes from the adjusting seat. The pressing member has hooking teeth corresponding to the bias rack in biasing direction and an elastic arm pressed by the adjusting seat so as to make the pressing member normally elastically outward pushed and swayable. The hooking teeth engages with the bias rack.
