Seaside Casual - MIA CORNER UNIT

Mia Corner Unit by Seaside Casual

The Mia Corner Unit is the key piece that transforms a straight Mia modular arrangement into an L-shaped or U-shaped sectional. It redirects the seating path by 90 degrees, creating intimate conversation corners and maximizing the use of patio corners and edges.

Every great sectional needs a corner, and the Mia Corner Unit delivers exactly that. It connects seamlessly to Armless, Left Arm Facing, and Right Arm Facing sections on both open sides, redirecting the arrangement to follow the shape of your outdoor space. The deep corner seat becomes a coveted spot — the person who claims the corner gets armrest-free sprawl in both directions.

EnviroWood Construction

This piece showcases EnviroWood, Seaside Casual’s recycled high-density polyethylene sourced from post-consumer milk jugs. Beyond its environmental credentials, EnviroWood is a genuinely superior outdoor material — it’s impervious to moisture, highly fade-resistant, and completely immune to insect damage and mildew. Concealed stainless steel hardware ensures lasting structural integrity. Manufactured in Rhode Island, USA, and available in multiple colors, it requires no painting, staining, or sealing.

Build Your Configuration

The Corner Unit is the pivot point of the Mia modular system. Place it where you want your arrangement to change direction — one Corner Unit creates an L-shape, two Corner Units (with Armless sections between) create a U-shape. Combine with Left Arm Facing (LAF) and Right Arm Facing (RAF) end sections to finish your custom layout.
