A saddle chair contains: a first seat and a second seat. The first seat includes a first connection sheet and an elongated orifice. The second seat includes a second connection sheet and a through orifice. A fixing member includes a slide slot having a slidable face, a receiving orifice, and a chute. A drive member is connected with a retainer via the receiving orifice, the elongated orifice, and the through orifice. The retainer includes a contacting face. Two screw bolts are screwed with the drive member via the retainer. A control bolt is screwed with a threaded orifice of the drive member and includes at least one recess on which at least one engagement block is fitted. Each engagement block has a screw and a forcing edge sliding between the slidable face and the chute, when the control bolt is rotated to move along the threaded orifice.

A collapsible stool entertainment system. The collapsible stool entertainment system includes an elongated rod having a first end opposite a second end. A seat portion is affixed to the first end and a base portion is affixed to the second end. A plurality of teeth extends from a lower surface of the base portion to engage a ground surface for additional stability. In some embodiments, the second end of the elongated rod is pivotally secured to an upper surface of the base portion via a ball-and-socket joint system, wherein the second end comprises a ball removably securable within a socket disposed on the base portion.

A device for moving the back and core muscles while sitting includes a rocking assembly that sits atop a base assembly, and optionally a height adjustment mechanism between the rocking assembly and the base assembly. The rocking assembly includes a rocking mechanism that sits between a base plate or platform and a seat. The rocking mechanism can be, for example, a hollow or solid hemispheric- or dome-shaped rocking mechanism, an eccentric bicylinder rocking mechanism, and/or a rocking mechanism based on an arrangement of halfpipe members. The rocking mechanisms of the exercise chair allow to the seat to rock, wobble, and/or swivel with a side-to-side rocking motion, a front-to-back rocking motion, or both a side-to-side rocking motion and a front-to-back rocking motion, and are attached to base plate and seat via a fastener that includes a solid strut that passes through the rocking mechanism and includes a plurality of Belleville washers.

The present invention is a moveable stool that includes a wheeled member having wheels, a stably support member and at least one flexible element. Stably support member is formed of a bottom cavity, a top flat surface for user to stand on and support element(s). When a user is not standing on top flat surface, then the wheels are free to move and stool is displaceable from one position to another. After the stool reaches at desired position and the user steps up on top flat surface, non-skid support element(s) connects with ground wheels of wheeled member are restricted from movement. Restricted movement of wheels prevents movement of stool on ground/floor. When user steps down from top flat surface, flexible element(s) retracts stably support member which raises support element(s) and disconnects contact between support element and ground. Wheels in contact with ground/floor are freed rendering stool again for portability.

A chair is provided having at least one leg with an upper end on which a seat component is supported and a backrest interconnected to and projecting from the seat component. The backrest comprises a lower backrest section, an upper backrest section, and a backrest hinge interconnecting the upper backrest section to an upper end of the lower backrest section. The lower backrest section is interconnected to and extends from a rear portion of the seat component and the backrest hinge is configured to permit the upper backrest section to be located in an upright position in which the upper backrest section projects above the lower backrest section and is configured to permit the upper backrest section to be pivoted to a forward position in which the upper backrest section extends laterally over and spaced above the seat component.

A torso supporting chair having a chair and front support. The chair has a seat support and at least one leg. The seat support having a top side and a bottom side, with the at least one leg attached to the bottom side. A front support is in functional combination the chair and may be integrally mounted with the at least one leg such that the front support is configured for seating of a user such that when the user is seated the chest of the user is adjacent and facing the front support. The torso support chair is configured to support the front torso of a user when seated.

Seat assemblies are provided. In some embodiments, a seat assembly includes a seat member having a first seat surface, a second seat surface, and a third seat surface opposite the second seat surface. The third seat surface is substantially parallel to the second seat surface and the first seat surface is substantially perpendicular to both the second seat surface and the third seat surface. The seat assembly also includes a first side panel affixed to the second seat surface and a second side panel affixed to the third seat surface. Each one of those panels is substantially perpendicular to the first seat surface. The seat assembly further includes a bin movably affixed to the first side panel and the second side panel. The bin includes an open compartment and can be moved between a dosed position that obstructs the compartment and an open position that permits access to the compartment.

The present disclosure provides a chair in which attachment strength of a holding member and the chair is enhanced and an attachment state can be stably maintained. A legged chair includes a leg member, a support post connected to the leg member, a metal frame integrated with the support post, the metal frame forming a seated portion, an awakening device configured to awaken a seated person, a battery configured to supply electric power to the awakening device, an ECU that controls the awakening device, and a holding cover configured to hold the battery and the ECU. The holding cover is attached to the highly rigid metal frame.
