Confirm quality, safety and performance with our testing and certification solutions

We have worked directly with both manufacturers and global retailers to evaluate outdoor furniture products more effectively.

Our outdoor furniture testing delivers consistency and the rigor of science-based evaluations of safety and durability. Products can be certified to UL 4041, Outline of Investigation for Outdoor Furniture, enabling manufacturers and retailers to evaluate the safety and quality of their products, mitigate risk of injuries during use, and empower consumers to choose safer and higher quality products.

Our testing and certification solutions facilitate a comprehensive quality evaluation of an outdoor furniture product’s mechanical and performance-related aspects of system durability. Our scientific testing helps clients evaluate their products’ performance and reduce the potential for product failures that could result in warranty claims.

Per UL 4041 requirements, the type of product determines the specific tests we perform. For example: 

  • We evaluate tables for leg strength, as well as overall stability and load-bearing characteristics under varying conditions. 
  • We test all chairs for stability, back and armrest strength, and component durability, while we also test chairs with pedestal bases for the durability of the chair base. 

UL Mark Certification to UL 4041 uses the enhanced mark which allows for more detailed information embedded about the product, such as the product model, location and manufacture date. This is specifically helpful for retailers and manufacturers in the event of a furniture recall.

Manufacturers who have their products tested and certified to UL 4041 demonstrate their commitment to quality, performance safety and their focus on customer satisfaction.

UL 4041 certification also provides retailers with confidence in the quality of the patio furniture products they buy and sends a clear message to both manufacturers and consumers regarding the company’s commitment to product safety.
