A seat (1000) may include mounting components (1054a. 1054b) that may mate with corresponding components on other assemblies. The seat may include one or more features that may rotate or move to provide for coupling to the one or more assemblies. Assemblies include, but are not limited to, a stroller, a bicycle adapter, a wagon, a booster seat, a camping chair, a high chair, a stadium seat/picnic table, a hiking pack, an infant carrier, a car seat, a booster car seat, or an airline seat.

A stadium chair has a seat frame and a backrest frame pivotally coupled to the seat frame for rotation about an axis parallel to a rear portion of the seat frame. The backrest frame is capable of forward rotation about the axis toward the seat frame and rearward rotation about the axis away from the seat frame. A biasing element coupled to either the seat frame or the backrest frame causes forward biasing of the backrest frame toward a neutral position relative to the seat frame. The biasing element allows for limited rearward rotation of the backrest frame from the neutral position and allows for forward rotation of the backrest frame from the neutral position. The chair preferably is configured to receive optional rotatable armrests that may be installed or removed without the use of tools.

A foldable support base for a foldable furniture with a flexible user support platform, in which a support frame has two side frame members, each pivotally connected to a load pivot joint along a load member with a load section extending beyond the load pivot joint which is pivotable about the first load pivot joint towards a center of the support frame. The load sections of the load members are configured for removably attaching a flexible user support platform therebetween. A load on the flexible user support platform results in a force component pulling on the load sections of the load members to cause the load members to pivot about the respective load pivot joints in a direction towards the flexible user support platform, thereby biasing to keep the side frame members to be spaced apart to maintain the support base in an extended configuration.

An elevated bench seating support including a top panel, a first brace and a second brace. The first brace is operably attached to the top panel. The second brace is operably attached to the first brace to retain a bench back between the first brace and the second brace when the elevated bench seating support is used in conjunction with a bench.

A bleacher seat with retractable and foldable armrests comprises two hook assemblies, a cushion assembly, a backrest assembly, two cushion-backrest connecting assemblies and two armrest assemblies, wherein the two hook assemblies are symmetrically arranged at the front end of the bottom surface of the cushion assembly, the lower ends of the two symmetrical cushion-backrest connecting assemblies are fixedly mounted at the rear ends of left and right sides of the cushion assembly respectively, and the upper ends of the two cushion-backrest connecting assemblies are symmetrically arranged at and rotatably connected to the lower ends of two sides of the backrest assembly. The two armrest assemblies are arranged symmetrically, the upper end and lower end of each armrest assembly are rotatably connected to a corresponding side of the cushion assembly and a corresponding side of the backrest assembly respectively, and the armrest assemblies are retractable; and a detachable cushion cloth is arranged on the cushion assembly, and a detachable backrest cloth is arranged on the backrest assembly. Armrests of the bleacher seat are retractable and foldable, all components are rotatably connected, and the cushion cloth and backrest cloth are detachable, so that the bleacher can be folded to be stored.
