Abstract: A furniture assembly is provided that allows to independently adjust height of furniture legs and thus adjust the angle at which the user-interfacing surface of the furniture, such as seat or tabletop, are positioned. This feature allows to set up the furniture for office-type use even in the outdoors and to compensate for sloped or otherwise uneven terrain. The furniture assembly can take form a chair, a sofa, or a table, with all of these furniture items being easily and conveniently foldable and unfoldable to allow for easy transport. Multiple safety features promote the furniture in staying in folded or unfolded configuration, as desired by the user, and prevent accidental change of configuration.
