Pennsylvania Resin Manufacturing Since 1945
Adams Manufacturing was founded in 1945 in Portersville, Pennsylvania, entering the plastics industry as injection molding technology was making resin products practical for consumer markets. The company developed expertise in UV-stabilized polypropylene — the same polymer used in outdoor furniture across the industry — and built a product line around the outdoor living category: Adirondack chairs, rocking chairs, patio seating, and folding step stools.
Eight decades of resin manufacturing in Portersville have produced deep material science expertise. Adams' UV-stabilization process prevents the chalking, fading, and brittleness that untreated polypropylene develops under prolonged sun exposure. The result is outdoor furniture that holds its color and structural integrity through seasons of outdoor use in American climates.
The Quik-Fold Design
Adams' Quik-Fold chair line represents the company's most significant design contribution to the outdoor furniture category: a resin Adirondack chair that folds flat for storage in a fraction of the space a traditional Adirondack requires. The engineering challenge was maintaining the wide-seat, low-back comfort profile of the classic Adirondack design while adding a folding mechanism robust enough for repeated use.
The solution uses a hinged seat back and slotted rear legs that allow the chair to collapse to a flat profile approximately 4 inches thick. Folded, a Quik-Fold Adirondack stores upright against a wall or flat in a garage. For homeowners with seasonal outdoor furniture storage requirements, this design addresses a genuine practical problem — the standard Adirondack is comfortable but nearly impossible to store in quantity.
Durable Outdoor Furniture for American Climates
Adams Manufacturing tests its outdoor furniture against the full range of American climate conditions: sustained UV exposure in southern states, freeze-thaw cycling in northern climates, and the humidity extremes of coastal environments. The 350-pound weight ratings on the Quik-Fold chairs reflect actual structural testing rather than nominal specifications.
For buyers choosing outdoor seating, Adams' Pennsylvania production and 80-year track record provide a level of product history that newer brands cannot match. A Quik-Fold Adirondack purchased today is the product of eight decades of incremental refinement in resin formulation, hinge engineering, and UV resistance — improvements that show up in real-world longevity rather than marketing claims.
