Multifunctional Use: The spacious pergola either has enough space to place 10 piece sofa sets, patio conversation sets, hot tub, dining sets, and even be as a parking shed. Protection Plan: 1 year for frame construction. Easy to assemble. Disclaimer: Furniture NOT INCLUDED. PURPLE LEAF doesn't offer installation service.

The outdoor louvered pergola features an adjustable hardtop louvered roof, providing shade customization based on your preferences. Its sturdy galvanized steel louvered roof and powder-coated aluminum frame ensure durability for all seasons, and reduce upkeep costs and enjoy more worry-free time. Moreover, the rainwater flows through the grooves between the leaves to the hidden drainage grooves on both sides when the top of the louver is closed. This louvered pergola is perfect for decorating your outdoor, backyard, garden, and poolside.
