About Adams Manufacturing
Adams Manufacturing has injection-molded resin outdoor furniture, step stools, and patio accessories in Portersville, Pennsylvania since 1945, making durable, weather-resistant products that American families have trusted for outdoor living for eight decades.
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.
