A drop-in seat deck for furniture assemblies. Various embodiments reduce the complexity and bulk of the seating frame, and also reduce the labor associated with assembly. Unlike the conventional spring suspensions, which apply constant spring loaded forces on the frame rails to maintain the springs in tension, the spring load force of the disclosed drop-in seat deck is provided by solely by the structure of the drop-in seat deck. Thus, the frame can be designed to support only the weight of the seated person is transferred to the rails of the seating frame, without consideration for pre-loading the seat deck. In various embodiments, dimensional changes to the seat deck occur under load. In some embodiments, these changes are accommodated by enabling a free end of the seat deck to slide on a support surface; in other embodiments, the changes are accommodated by flexures that are integral to the seat deck.

1. A furniture assembly, comprising: a seating frame including a first support member and a second support member, said first support member and said second support member being substantially parallel and extending in a lateral direction; anda seat deck comprising a composite polymer material and including a first edge structure and a second edge structure, said first edge structure defining a channel dimensioned to capture an upper edge of said first support member, said first edge structure being fixedly attached to said first support member of said furniture assembly, said seat deck including an elongated slat member that is coupled to said first edge structure and said second edge structure, said elongated slat member extending between said first edge structure and said second edge structure in a fore-and-aft direction that is perpendicular to said lateral direction,wherein said elongate slat member defines a convex arcuate profile that is convex in an upward direction, said convex arcuate profile defining a local maxima of said elongate slat member,wherein said elongated slat member is one of a plurality of elongated slat members of said seat deck, said plurality of elongated slat members extending in said fore-and-aft direction, said seat deck including lateral tie members that tie said plurality of elongated slat members together in said lateral direction, said plurality of elongated slat members being unitary with said second edge structurewherein said second edge structure defines a channel dimensioned to capture an upper edge of said second support member, said second edge structure being fixedly attached to said second support member of said furniture assembly,wherein said seat deck includes flexures that bridge said elongated slat member to said first edge structure and said second edge structure, said flexures being configured to accommodate a change in a length of said elongated slat member of the seat deck in said fore-and-aft directions when said seat deck is under a weight load. 2. The furniture assembly of claim 1, wherein said composite polymer material comprises a 10% to 20% glass filled polypropylene. 3. The furniture assembly of claim 1, wherein the furniture assembly is a sofa. 4. The furniture assembly of claim 1, wherein said flexures are configured to accommodate a maximum change in said length of said elongated slat member of said seat deck in said fore-and-aft directions, thereby enabling said elongated slat member to transition from said convex arcuate profile to an inverted profile that defines a concavity. 5. The furniture assembly of claim 1, wherein at least one of said flexures defines a node and a flexure axis that passes through said node, said flexure being configured to flex about said node and said flexure axis when a force component is exerted on said at least one of said flexures in said fore-and-aft directions. 6. The furniture assembly of claim 5, wherein said flexure axis is orthogonal to said fore-and-aft directions. 7. The furniture assembly of claim 6, wherein said flexure axis is substantially parallel to said lateral direction. 8. The furniture assembly of claim 5, wherein said at least one of said flexures defines a second node and a second flexure axis that passes through said second node, said at least one of said flexures being configured to flex about said second node and said second flexure axis when said force component is exerted on said at least one of said flexures in said fore-and-aft directions. 9. The furniture assembly of claim 8, wherein said second flexure axis is parallel to said flexure axis. 10. The furniture assembly of claim 9, wherein said at least one of said flexures is an S-shaped flexure. 11. The furniture assembly of claim 5, wherein said at least one of said flexures is configured to provide a stop in the fore-and-aft directions to limit deflection of said elongated slat member in a downward direction. 12. The furniture assembly of claim 5, wherein said at least one of said flexures is a canted arm flexure configured to stop against said seating frame to limit deflection of said elongated slat member in a downward direction.
