A knee-rest economic chair is provided. The knee-rest economic chair is formed from a unitary construction, fastener-less assembly, wherein the chair provides an elevated posterior condition as an elevated knee rest for seated users. The chair may be assembled from a plurality of components all of which are formed from a planar blank of one material. The components have tabs and slots for joined adjacent components that results in a seat component spaced apart and elevated above a knee support component, positioned relative to each other in an elevated posterior position, wherein gravity secures the resulting tab-slot and slot-slot joints, making separate fasteners unnecessary.

The present disclosure discloses a multifunctional balance chair comprising a support portion, a seat portion, and a kneeling cushion portion. The seat portion is movably connected to the support portion, and an angle between the seat portion and the horizontal plane is controlled by relative movement between the seat portion and the support portion. The kneeling cushion portion is movably connected to the seat portion and connected to the support portion by a connecting mechanism. The kneeling cushion portion is movable between a first position aligned with the seat portion and a second position in which the kneeling cushion portion constitutes a balance chair cushion. The movement of the seat portion is linked to movement of the kneeling cushion portion.

A foldable massage chair, including a face pillow assembly for supporting a user's head, a chest pillow assembly for supporting the chest, a handrail assembly for supporting wrists, a front support piece, a seat cushion assembly, a main supporting frame, a kneeboard assembly, and back and a front supporting leg assemblies. When using this chair, it is placed in an expanded or use position, so a user may sit on the seat cushion and lean on the massage chair, completely exposing his back, waist, and hips for a masseur to massage. When the chair needs to be put away, it is possible to fold the chair into a collapsed position by folding the seat cushion assembly, front support piece, chest pillow assembly, and handrail assembly. Also, the front and back supporting leg assemblies are folded underneath and towards the main supporting frame. Consequently, the size of the entire chair decreases.

When a user needs to use this chair, it is placed in an expanded or use position, so the user may sit on the seat cushion and lean on the massage chair, completely exposing his back, waist, and hips for a masseur to massage. When the chair needs to be put away, it is possible to fold down the chair into a collapsed position by folding the seat cushion assembly, front support piece, chest pillow assembly, and handrail assembly. Also, the front supporting frame is folded towards the back supporting frame. Consequently, the size of the entire chair decreases.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.

A chair for supporting a body of a user in a substantially upright position relative to a vertical-axis; the chair includes a frame, a chest-support, a seat and at least one knee-support. In a preferred embodiment, the chair includes a tray configured to hold items/tools such as dentist equipment. The chair is useful for supporting the body of the user who needs to be seated for a prolonged period of time, to prevent un-comfort associated with the same.

A convertible chair adapted for conversion between a sitting configuration and a kneeling configuration includes_a base support, a knee-back rest movably coupled to the base support by a pivot arm, a seat movably coupled to the base support by a coupling mechanism, and a connecting arm linking the pivot arm and the seat. The seat is arranged to move relative to the base support between a first seat position corresponding to the sitting configuration and a second seat position corresponding to the kneeling configuration. The pivot arm is arranged to pivot relative to the base support between a first pivot arm position in which the knee-back rest is in a first knee-back rest position for use as a back rest and a second pivot arm position in which the knee-back rest is in a second knee-back rest position for use as a knee rest.

The invention relates to the field of ergonomic furniture. The device (1) comprises an upper support element (8) for supporting the thighs and a lower support element (9) for supporting the legs or tibias, that can be separated by an open space (11) or recess for the knees. An assembly (7) formed by the two support elements (8, 9) is mounted so that it pivots around a horizontal axis (A) on a bearing structure (2, 6), wherein rotation of the assembly (7) enables the support elements (8, 9) to accompany the lower limbs of a user during a transition from one use position to another. The device (1) is incorporated into an apparatus for maintaining a standing or sitting-standing position, having at least one footrest (4, 5). The device is applicable to the arrangement of a workstation, such as a computer workstation or an industrial workstation.

An assistive device for standing tasks allows for a reduction of effort on the part of a user while engaged in tasks or activities that are stationary or nearly stationary that lessens the strain on the bones, joints, and muscles normally used for standing while ensuring a proper alignment of the pelvis and spine.
