Leeward Deep Seat High Back Three-Seat Sofa

Details at a Glance

When you need deep cushioned comfort that won't rust or rot after a season under cover, Marine Grade Polymer delivers where aluminum and wood frames fail. The Leeward Deep Seat High Back Three-Seat Sofa, a 78-inch outdoor sofa with non-porous MGP construction and 38-inch high back support, is available at LOOMLAN Outdoor with free shipping. The sled base distributes weight evenly across uneven decking, and you can order it in over 20 frame colors with 100+ Sunbrella cushion fabrics to match your patio.

What Makes Marine Grade Polymer the Best Frame Material for Covered Patios?

Marine Grade Polymer won't rust, rot, crack, or absorb water the way aluminum oxidizes and wood swells. The material is non-porous, so moisture can't penetrate the frame -- rain beads off, humidity doesn't cause expansion, and salt air won't corrode the structure. MGP holds its color through years of UV exposure because the pigment runs through the entire thickness, not just a surface coating that chips or fades. You'll wipe the frame clean with mild soap and water, no annual sealing or rust treatment required.

Can This Sofa Stay on a Covered Porch Year-Round?

Yes, if your porch has a solid roof that keeps direct rain and snow off the frame. MGP itself can handle freeze-thaw cycles without cracking, but you should store the Sunbrella cushions indoors during heavy rain or winter -- they're water-resistant and quick-drying, not waterproof. If you're in a climate with hard winters, bring the cushions in and leave the frame outside under cover. The sled base sits flat against the deck, so wind won't catch and tip it.

How Do You Set Up a Deep Seat Sofa for Maximum Comfort?

Pair this three-seat sofa with a coffee table or side tables from our outdoor accessories collection to anchor a full conversation area. The 22-inch seat depth and 38-inch high back support adults up to 6'2", so you can layer throw pillows without crowding the seating space. If you're building out a larger covered porch, coordinate with modular units or add outdoor accent chairs on the sides, then browse outdoor sofas and loveseats to see matching deep seat loveseats.

Frequently Asked Questions

Will the MGP frame fade in direct sun?

The pigment runs through the entire material thickness, so the frame resists UV fading far better than surface-coated aluminum or stained wood. You won't see the color fade or chip after seasons under cover.

Is this suitable for a coastal or salt-air location?

Yes -- Marine Grade Polymer is non-corrosive and non-porous, so salt air won't oxidize or pit the frame the way it does with aluminum. Rinse the frame occasionally to remove salt residue.

Do the Sunbrella cushions need to come inside every night?

No. Sunbrella fabric is water-resistant and quick-drying, so it can handle overnight dew and light rain. Store cushions indoors during heavy downpours or winter, since they're not fully waterproof.

How much assembly is required when it arrives?

Minimal -- the frame ships fully assembled, and the cushions require no installation. Free curbside delivery is included to the continental USA.

Can you customize the frame and cushion colors?

Yes, the sofa is made to order with over 20 MGP frame colors and 100+ Sunbrella fabric options. Lead time is 6-8 weeks.

Does the sled base stay stable on uneven patio pavers?

Yes -- the continuous sled-style legs distribute weight across a wider footprint and won't rock on slightly uneven decking or pavers the way four individual legs can.
