A yoga or exercise stool may have a seat portion and a base portion; the base portion having window slot(s) formed in a front side, a rear side, or both; a handle slot formed at least in one side, such as the front side, at or near the top; horizontal gripping slot(s) formed in the left side, the right side, or both, at or near the top; and vertical gripping slot(s) formed in the left side, the right side, or both, at or near the bottom; advantageously four such slots being formed near the bottom corners of the left and right sides. A yoga stool also may have a base portion, and a seat portion on top of the base portion, wherein the seat portion has an internal firm support member such as a solid slat, and preferably softer material such as foam rubber surrounding the support member, at least on the left and right sides. The yoga stool may include opposed side elements joined by a rear element and front element with a removable top element that may be U-Shaped to allow for additional poses or exercises.

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. The apparatus includes a vertically movable armrest assembly. 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. The armrest assembly can be translated vertically to accommodate the user's body to achieve desired positioning.

The invention relates to a chair, having a chair base (1), a seat part (5, 6, 7, 8) connected thereto, a backrest (9, 16, 17) connected thereto, the seat part (5, 6, 7, 8) pivotable about at least one horizontal or inclined horizontal axis and the backrest (9, 16, 17) are spatially adjustable. The seat part (5, 6, 7, 8) has at least three seat elements (5, 6, 7) that can be adjusted in relation to one another and whose operating positions can be adjusted individually.

A seat cushion is provided. The seat cushion includes an upper pad, a lower pad, a support structure, a plurality of optical modules, and a processor. The upper pad includes a plurality of transparent areas. The lower pad is provided with a plurality of grooves to accommodate the optical modules. The support structure is connected between the upper pad and the lower pad. The optical modules are located below the upper pad and are disposed corresponding to the transparent areas. The optical modules respectively transmit sense signals and respectively receive feedback signals corresponding to the sense signals. The processor is coupled to the optical modules and is configured to collect optical signals.

To realize a noble, useful seat with a simple structure designed to follow a natural movement of a seated person in front-rear and left-right directions and to support appropriately a movement of the person continuously changing its posture while the person balances a load. The seat includes the elastic support layer 3 and upper and lower base units 4 and 5 arranged to sandwich the elastic support layer 3. The upper base unit 4 includes the rolling surface 42e bulging toward the lower base unit 5 thereabove via the elastic support layer 3, is rollable in a 360° direction from the tilt reference position IRP in receiving a load of the seated person, and has a moving distal end side tilting more downward as a distance from the position IRP increases, and is configured to move while compressing the elastic support layer 3 by the rolling surface.

A chair includes a movable part including a seat on which a user sits, a supporting part configured to support the movable part in such a way that the movable part can be moved to the right and to the left; and a restoration unit, which is a biasing member configured to bias the movable part toward the neutral position in the right and the left. The supporting part supports the movable part in such a way that the movable part descends as the movable part is away from the neutral position.
