Systems, devices, and methods are provided for furniture with integrated internal storage chambers that are sealable and operable to contain items.

A sun lounger cover has a main body portion configured to in use rest substantially flat against and at least partly cover the upper surface of a sun lounger, and an occupancy status indicator configured to indicate the occupancy status of the lounger.

An outdoor chaise lounge including a lock-box integrated therein. The chaise lounge may have a photovoltaic device mounted to a portion of a seat member where a user rests his or her head, and the lock-box may be positioned below a foot portion of the seat member. The foot portion of the seat member may be configured to be rotated upwards to enable a user to access the lock-box. In an embodiment, electronic devices may be integrated into a member of the chaise lounge, such as a leg member, frame member, or armrest, and be configured to enable a user to order food, beverages, attendants, or perform other communications with a billing or other system of a venue (e.g., hotel, cruise ship, etc.) via a wireless communication.

A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.

A solar-powered umbrella has a cap structure that is connected by hinges to struts. The struts are relatively rigid and positioned above the umbrella shade and house solar panels. When the umbrella is opened and closed, the struts rotate via the hinges from an open to closed position. When the solar panels are exposed to the sun, light is converted to electrical energy to charge a rechargeable battery. The battery supplies power to one or more USB ports. A user can recharge an electronic device (e.g., smartphone or tablet computer) by connecting to a port of the umbrella using a cable.

An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.

A multifunctional chair apparatus that may be configured into the following separately definable and useful structures: (1) a flat-bed assembly; (2) a reclining lounger assembly; (3) a beach chair assembly having a first seat height; (4) a beach chair assembly having a second seat height; (5) a cart assembly; and (6) a compact folded assembly. The multifunctional chair apparatus may include a frame having a primary frame assembly and a secondary frame assembly being foldably connected by a central hinge assembly at a central portion of the frame. The primary frame assembly may be comprised of two or more smaller frames separated and rotatably connected by a primary hinge assembly. The secondary frame assembly may be comprised of two or more smaller frames separated and rotatably connected by a secondary hinge assembly. The hinge assemblies include lockable hinges that selectively lock at angles of 0, 100, 140, and 180.

A multifunctional folding chair and wheeled cart system and kit includes a multifunctional folding chair that easily convert into a fully unfolded configuration of a flat bed, a partially folded configuration of a reclining lounger, an upright lounger, a short beach chair, and a regular chair, and a fully folded configuration. The system also includes at least one multifunctional wheeled chair that includes, in addition to the configurations of the multifunctional folding chairs, a partially folded configuration of a wheeled cart. The multifunctional wheeled chair, in the wheeled cart configuration, is configured to hold and transport the plurality of multifunctional folding chairs in the folded configuration.

A collapsible/foldable and portable chair that can be transformed or converted between a chair and a cart for carrying items, and can be collapsed to a compact form for stowing. The chair cart includes a foldable chair having a seat base, a seat back pivotally attached to the seat base, and a leg rest pivotally attached to the seat base. In the collapsed configuration, the seat base, the seat back and the leg rest are folded to collapse the chair into a compact form. In the chair configuration, the seat base, seat back and the leg rest are unfolded to extend the chair to provide support surfaces for the person's back, buttock and legs. In the cart configuration, the leg rest is folded upwards with respect to the seat base to define a storage space above the seat base and between the foot rest and the seat back.

An expandable and collapsible support device for multiple use enables attaining an expanded open state for use or return to a compact closed state in mere seconds. The device includes an accordion-style frame that expands laterally from a compact closed state to an expanded open state for use, and a material support cover forming the top of the device and attachable to the frame to provide a support surface above ground level for the device.
