DEX Collection by Seaside Casual — Contemporary Outdoor Living, Redefined

The DEX Collection by Seaside Casual at Addi’s Patio brings modern design and modular flexibility to your outdoor space. With clean lines, deep seating, and a versatile layout, DEX is designed to adapt to your lifestyle—whether you’re hosting guests, lounging solo, or creating a statement seating area for your patio or deck.

Crafted in the USA from EnviroWood®, Seaside Casual’s recycled HDPE lumber, the DEX Collection combines eco-friendly durability with sophisticated style. Its frames resist fading, moisture, and cracking, while marine-grade stainless steel hardware ensures lasting performance. Plush, weather-resistant cushions add unmatched comfort, making this collection a perfect balance of resilience and relaxation.

From sleek sofas and sectionals to coordinating tables and lounge seating, the DEX Collection makes it easy to create a personalized outdoor retreat with a distinctly contemporary edge.
