A submergible stool includes a body having a top, a bottom spaced from the top, and a sidewall extending between the top and the bottom and defining an enclosed interior cavity extending between the top, the bottom, and the sidewall. A first aperture is formed in the sidewall proximate the bottom and extends from the enclosed interior cavity to an exterior of the stool. A second aperture is formed in the sidewall proximate the top and extends from the enclosed interior cavity to an exterior of the stool. The apertures are positioned such that when the stool is placed in a body of water, water will flow into the interior cavity through the first aperture, air will be forced out of the second aperture, and the stool will sink to a bottom of the body of water in an upright position.

There is provided an ergonomic chair which is produced from flat components. The components may be made of paper. The components are designed using parametric equations which take the targeted user's proportions into account. The components are then folded, joined, and coated with strengthening material. The chair has a seat, a base, and three legs connecting the seat to the base. The base contains a counterweight mass for keeping the chair in a default upright position. The base contains an accelerometer which can transmit data to a computing device to track a user's posture and other health-related data.

The presently claimed subject matter is directed to furniture elements. Further, the presently claimed subject matter concerns a furniture covering element configured with a cushioning arrangement.

The present invention relates to ergonomic supports in medical environment. In order to provide improved ergonomic support while providing a minimum impact of the user's activities, an ergonomic support device (10) for users in medical environment is provided. The support device comprises a seating support arrangement (14), an X-ray shielding arrangement (18) and a base support structure (12). The base support structure provides mechanical support for the seating support arrangement and the X-ray shielding arrangement. The seating support arrangement comprises a seat support surface (16) that is configured for supporting a buttocks area of a user. The X-ray shielding arrangement comprises at least one X-ray shield (20) that is configured for shielding at least a part of an X-ray radiation to which a user is exposed to while supported by the support surface. The at least one X-ray shield is movably mounted to the base support structure to be adjustable in its position relative to a user at least partly resting on the seat support surface.

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.

A convertible seat including: a support frame; and a user support having a support surface on one side defining a rounded periphery, the user support being movable from a first configuration supported by the support frame with the rounded periphery presented upwardly, to a second configuration supported by the support frame such that a seat or seat base is presented upwardly, the seat or seat base being substantially flat or at least less rounded than the rounded periphery, with the support surface being stowed substantially below the seat or seat base in the second configuration. The seat allows the attainment in a single unit both the healthy balance/core-strengthening of a fitness chair and a conventional chair.

A tiltable stool includes a seat which is connected to a base by an elongated body structure. The base has an upper base element and a lower base element. The upper base element is resiliently deformable. The resiliently deformable upper base element allows the stool to pivot in any direction. The lower base element is a rotationally symmetrical outwardly convex and inwardly concave body. The upper base element may include one or more annular grooves.

A tiltable chair includes a fixing base having a tiltable housing. A gas cylinder inside the tiltable housing reciprocates in upward and downward directions. A seat plate is on top of the gas cylinder. And an elastic tiltable member is inside the fixing base accommodates a longitudinal lower part of the gas cylinder so the gas cylinder moves tiltably about a vertical axis to the bottom of the fixing base. A fixed frame is on the bottom of the fixing base, a coupling frame is inside the center portion of the fixed frame to accommodate the gas cylinder therein, and a rubber packing is between the fixed frame and the coupling frame and deformed elastically in every direction. The rubber packing has tilt concave grooves formed inward to a given depth from top and underside reduced in width toward the insides thereof to form inclined surfaces.
