MIULEE 24x24 Outdoor Seat Cushion Black — Waterproof, Anti-Slip Patio Cushion with 4" Foam

MIULEE’s 24 x 24-inch waterproof outdoor seat cushion delivers durable, slip-resistant comfort for patio chairs with fast-drying protection and long-lasting color.

Built to handle sun, spray and everyday outdoor use, this MIULEE cushion combines a dual-layer waterproof system with anti-slip detailing and resilient foams so your seating stays comfortable and secure. The design balances weather resistance and supportive padding while remaining easy to move, clean and install on most outdoor furniture.

How does this cushion keep water and stains out?

The cushion uses a two-step barrier: an outer Durable Water Repellent (DWR) coating sheds light rain and spills, while an inner TPU layer blocks water migration into the fill. A wide zipper with a double-overlap flap further reduces seepage along seams.

• Outer DWR finish repels surface moisture and stains
• Inner TPU membrane prevents liquid penetration to the foam
• Zipper with overlap flap for added seam protection
• Removable cover for quick spot-cleaning or full washing

Will the cushion stay in place on my outdoor chairs?

Yes—MIULEE added anti-slip silicone dots across the entire bottom plus adjustable straps to anchor the cushion to most chair frames. These features minimize slipping and shifting, even when the furniture is used frequently.

• Anti-slip silicone pattern for stable seating
• Adjustable straps secure the cushion to a variety of chair styles
• Built-in handle makes repositioning simple and fast

What kind of comfort and support can I expect?

This set pairs a 28D high-resilience foam seat that holds its shape with a firmer 15D fiber back for upright support. The combination delivers balanced cushioning—soft enough for relaxation but supportive enough for longer sitting periods.

• Seat: 24" W x 24" D x 4" H with 28D resilient foam
• Back: 25.5" W x 19.5" H with firmer 15D fiber fill
• Designed to resist flattening while preserving comfort

How long will the color last outdoors?

Made from solution-dyed, high-density Oxford polyester, this cushion resists fading under prolonged sun exposure. It has been tested for colorfastness up to 1500 hours, providing up to three years of maintained vibrancy under typical outdoor conditions.

• Solution-dyed fabric for deep, long-lasting color
• High-density weave improves UV resistance
• Tested to withstand extended sun exposure without rapid fading
