A chair includes a first fabric panel having a first end and a second end opposite the first end, a second fabric panel coupled to the first panel between the first end and the second end such that the second fabric panel divides the first fabric panel into a seat section between the second fabric panel and the first end and a rear section between the second fabric panel and the second end. Back support poles are received within sleeves extending along sides of the second fabric panel. The chair further includes cross support poles having ends coupled to the back support poles and opposite ends coupled to the second end of the second fabric panel. The cross support poles cross one another. The chair has an overall weight less than 12 ounces.

A dynamic furniture system includes a first frame portion; a set of rollers mounted to the first frame portion; a second frame portion including one or more rockers having a roller-interface surface having a curved profile; wherein the set of rollers interface with the roller-interface surface of the rockers such that the second frame portion is moveable relative to the first frame portion; a set of one or more electromagnets mounted to or integrated with the first frame portion or the second frame portion; a set of one or more magnetically-interactive elements mounted to or integrated with a different one of the first frame portion or the second frame portion; and an electronic control system configured to vary a parameter of electrical energy supplied to the set of electromagnets over time to induce back and forth motion of one of the first frame portion or the second frame portion.

The present invention relates to a collapsible chair. The chair includes a backrest for engaging with a sitter's back. A seat extends from the backrest and is where the sitter can sit. A retractable leg support may extend from the seat and can be extended to support the sitter's legs with feet off the ground. Advantageously, the sitter's feet may be safely off the ground away from ants and sand.

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.
