Summsun Outdoor Round Chair Cushions Set of 2 — 15" x 3" Cream, Waterproof Polyester & 28D High-Density Foam

These are a pair of 15" diameter, 3" thick round outdoor chair cushions from Summsun, made with waterproof, fade-resistant polyester covers, 28D high-density foam, and secure non-slip ties for patios and bistro seating.

Designed to update outdoor seating with simple comfort and weather-ready durability, these Summsun round cushions come as a set of two in a neutral cream color. Each cushion measures 15 inches across and 3 inches high, fitting common garden chairs, bistro sets, wicker seats, and porch furniture. The covers are made from 250gsm polyester engineered to resist moisture and fading, while the high-density 28D foam provides lasting support. Zippered, removable covers and attached ties make these cushions practical for season-to-season use and easy to keep clean.

How well do these cushions stand up to sun and rain?

The outer fabric is a weather-resistant 250gsm polyester with anti-fade treatment, designed to repel moisture and slow UV damage so the cushions retain color and resist light water exposure. They are not sealed waterproof shells for submersion, but they shed rain and dry quickly compared with untreated fabric.

• 250gsm polyester cover resists water and reduces staining.
• Anti-fading treatment helps maintain cream color outdoors.
• Quick-dry properties minimize mildew risk after light rain.
• Not intended for continuous immersion or winter storage outdoors.

How comfortable and supportive are the 3" cushions?

Each cushion is filled with 28D high-density sponge that offers firm, rebound support to reduce pressure on hips and lower back during extended sitting. The 3-inch thickness strikes a balance between slim profile and cushioning, suitable for dining chairs and bistro seating where space and posture matter.

• 28D high-density foam provides resilient, long-lasting support.
• 3" thickness offers comfort without raising seat height excessively.
• High-rebound foam helps cushions keep their shape over time.
• Works well on wooden, metal, and wicker chair frames.

Will these cushions stay in place and are they easy to clean?

Each round cushion includes two durable fabric ties to secure it to a chair and reduce slipping; these work well on rounded or straight chair backs. When it’s time to clean, the cover unzips and is machine washable, so you can remove dirt and freshen the cushions without replacing the foam core.

• Two sewn ties per cushion keep them anchored to seating.
• Zippered removable covers allow machine washing for simple care.
• Washing the cover preserves the foam interior and extends life.
• Shake or fluff the cushion after washing and drying to restore loft.

How will these cushions arrive and how do I prepare them for use?

To reduce shipping volume, cushions are compressed for transit; they may look thin or slightly misshapen on arrival but recover within 1–3 days. Gently shaking and fluffing speeds expansion, and allowing time helps the foam regain full thickness and comfort.

• Ship-compressed to save space—allow 1–3 days to expand fully.
• Gently shake and knead cushions to help the foam rebound.
• If needed, let cushions sit in a warm, dry area to accelerate recovery.
• Inspect zipper and ties before first use to confirm fit and function.

Who is this for: These Summsun round chair cushions are aimed at homeowners and renters who want an easy, attractive upgrade for patio, porch, or bistro seating. They suit people who need a compact, weather-ready cushion with removable covers for regular cleaning—ideal for café-style outdoor sets, small balconies, garden benches, wicker chairs, or any seating where a low-profile, durable pad is preferred.
