A seating unit includes a chair with a backrest and a hook assembly. The backrest includes a rear surface having an outwardly protruding rim. The hook assembly comprises a cover plate and a weldment, and the cover plate may include a hook being integrally formed on an exterior face. The hook assembly is configured to be securely coupled on or within the outwardly protruding rim of the backrest, and a secure coupling between the hook assembly and the backrest is formed via insertion of a fastening member, which is inserted through an apertures on a bottom surface of the cover plate, such that the fastener is aligned substantially parallel to the rear surface.

A seating arrangement for interactive learning is disclosed herein. The arrangement comprises a chair for supporting a child thereon; a tray removably supported on the chair; and at least one interactive media configured on the tray for facilitating interactive learning to the child supported on the chair. In an embodiment, the interactive media may include an electronic interactive device such as a tablet. In another embodiment, the interactive learning media may include a writing pad and a stylo for allowing the child to practice the usage of the stylo on the writing pad. In an embodiment, the writing pad may be an electronic writing pad.

The convertible hand truck and chair device may combine the advantages of a wheeled hand truck with the advantages of a folding chair. Such a design may allow a user to transport large or heavy items from one location to another using the hand truck, and to then utilize the hand truck as a chair device for sitting. By way of example, a user going to the beach or a camp site may carry most or all of their needed items, such as coolers, foodstuffs, and other goods, to the beach or camp site location, and then convert the hand truck to a seat where they may sit or rest without the need to bring an additional chair. The device may further collapse down into a compact form factor for ease of transportation.

The present invention relates to stabilization of RNA, in particular mRNA, and an increase in mRNA translation. The present invention particularly relates to a modification of RNA, in particular in vitro-transcribed RNA, resulting in increased transcript stability and/or translation efficiency. According to the invention, it was demonstrated that certain sequences in the 3′-untranslated region (UTR) of an RNA molecule improve stability and translation efficiency.

The present application relates to a shop chair with a seat cushion supported by a strong, light-weight base assembly with an elevated central hub that threadably receives a central column to adjust the height of the seat cushion. The base includes several vertically oriented thin plate legs that extend radially outward and downward from a central hub. The outer ends of the legs are joined by a stabilizing ring with a diameter larger than the seat cushion. Oversized caster wheels and the large footprint of the base provide a stable work platform. The seat cushion can be selectively lowered until the bottom of the central post is proximal to or contacts the ground. The chair and its base are particularly suited for work done closer to the ground.

A tilting seat for operators in a controlled environment, particularly for surgeons and the like, comprising a saddle, a chest support, a forehead support and a leg support connected to a base standing on the ground, such that the saddle, the chest support, the forehead support and the leg support are integrally movable with rotation about a horizontal-axis joint placed below the saddle, keeping the space over the joint free from movable elements while in use, guaranteeing the substantial lack of contamination in such space.

The invention relates generally to a lightweight, collapsible, and portable wheeled seat, e.g., a wheeled office chair or stool, for travel, storage, and mobility. The seat includes a seat base member and a seat surface member collapsible between an open, extended position, which is configured to provide a seating surface, and a collapsed, closed position. The seat surface member includes a central seating surface member fixed to the seat base member that has an outer perimeter, and a pair of oppositely disposed and generally u-shaped seating surface members pivotally secured to the seat base member. Each of the generally u-shaped seating surface members include a pair of leg portions that extend from a base portion thereof, or an inward directed perimeter and a portion of each inward directed perimeter has a shape that substantially complementarily corresponds to a shape of a portion of the outer perimeter of the central seating surface member.

A reclining chair or the like provides a set of base-mounted extendable arms that extend outward as the chair reclines to brace the chair against tipping. A force-limiting coupler allows the reclining mechanism and the extendable arms to be linked while maintaining different force regimes.

Disclosed are a chair device and a star-shaped base (3) thereof, in particular capable of being used for office chairs, work chairs, stools or standing auxiliary devices, the star-shaped base comprising a center seat (4) and a plurality of extending arms (5) mounted on the center seat (4), wherein the extending arms (5) are used for the star-shaped base (3) to be placed on the ground, and at least one of the extending arms (5) is hinged to the center seat (4) and can rotate relative to the center seat (4). A chair seat of the chair device can rotate or swing, while parts mounted at an upper end of a chair column do not need to be modified, and particularly, a supporting structure, a chair support for the chair seat to be placed, and the chair seat itself do not need to be modified.

Exemplary aspects of the present invention are directed to a reconfigurable dolly that may include a base, one or more base plates, that may be removable from the base and nest within the base, and one or more caster wheels connected to the base to allow for movement of the reconfigurable dolly relative to the surface on which the reconfigurable dolly may be positioned. The base of the reconfigurable dolly may be configured to be coupled to a base receiving tube. The base receiving tube may be configured for telescoping receipt of a seat receiving tube. The seat receiving tube may be telescopically positionable within the base receiving tube. The seat receiving tube may be configured for receipt and retention of an adjustable seat.
