The perfect combination of structure and sink-into-it comfort, Porto frames are craftsman-built from all-weather tube and cast aluminum, featuring precision welds and reinforced stress points. Frames feature a no-sag, recycled-steel, sinuous support system and a network of flexible webbing beneath seat cushions for evenly dispersed, firm yet flexible comfort. Outdoor cushions are padded with high-resiliency, antimicrobial foam covered in weather-resistant, solution-dyed olefin fabric. Dense foam padding enables high elasticity, providing ideal support and distributing pressure across cushion surfaces—helping seats bounce back from heavy use. Polyester fibers encase foam cushion cores to provide additional comfort. Cushion fill is completely sealed in a water-repellent covering to enhance cushion strength and longevity. Protect your outdoor furnishings with resilient Sur Last® covers—specifically tailored to fit Arhaus outdoor collections. Speak to a design consultant for details.
