The Mainstay Sectional 3-Piece Sofa is a modular outdoor seating set made for large patios, decks, or outdoor living spaces. It comes with three pieces: a middle section and two armchair end pieces, allowing you to arrange them as one long sofa or separate as needed.

The frames are crafted from high-density UV-stable resin that resists fading, warping, splintering, and cracking in direct sunlight or harsh weather. The cushions use marine-grade outdoor fabrics and quick-dry foam for comfort and durability. Straps or buckles secure the cushions to the frame to keep them in place.

Seat height is about 16.5 inches, with overall dimensions approximately 105 inches long, 35 inches deep, and 29 inches tall. It is designed for full outdoor exposure but not for being submerged in water. This set includes cushioning and throw pillows in coordinated colors, which can be customized from a selection of fabric tones.
