Zonamat Outdoor Chair Cushions Set - Deep-Seat 24" x 24" + 25" x 22.5", Waterproof & UV-Resistant

Zonamat Outdoor Chair Cushions are a waterproof, UV-resistant deep-seat cushion set engineered to keep outdoor seating comfortable, supported, and color-fast through changing weather.

These cushions arrive as a coordinated pair: a 24" x 24" x 5.75" high-density seat pad and a 25" x 22.5" backrest pillow, sized to fit most deep-seat patio chairs and loveseats. Built with a water-resistant Oxford polyester outer shell and a TPU-laminated inner barrier, the covers help prevent moisture from reaching the interior foam. Yarn-dyed fabric and UV-protective treatment reduce fading from sun exposure, while upgraded fillings—firm high-density foam in the seat and a memory-foam blend in the back—balance support and plush comfort.

How do these cushions stand up to rain, spills, and outdoor moisture?

The cushions use double-sided waterproof construction: a durable Oxford polyester shell combined with a TPU laminated lining beneath the cover to block liquid. This design keeps the foam drier and slows mildew development compared with standard outdoor cushions.

• Oxford polyester outer fabric repels surface water.
• TPU-laminated inner layer creates a moisture barrier.
• Hidden zipper allows quick removal for spot cleaning.
• Reinforced seams and piping prevent water entry at stress points.

Will the cushions maintain their color and shape under sun exposure?

Zonamat cushions are made from yarn-dyed, UV-protective fabric for improved color retention and fade resistance versus printed materials. The seat uses resilient high-density foam that resists flattening, while the back pillow’s memory-blend filling preserves loft and lumbar support.

• Yarn-dyed construction increases long-term color stability.
• UV treatment reduces fading from regular sunlight.
• High-density foam keeps seat firmness over time.
• Memory-foam blend softens pressure points without collapsing.

Do these cushions fit most outdoor chairs and how are they secured?

The set is sized for deep-seat furniture—24" square for the seat cushion and a 25" x 22.5" back pillow—so they match many patio sofas, wicker chairs, and deep loungers. Built-in adjustable ties and discreet attachment points help keep the cushions in place during use and light breezes.

• Seat cushion: 24" W x 24" D x 5.75" T for deep-seated furniture.
• Back pillow: 25" W x 22.5" H for full back coverage.
• Adjustable ties prevent slipping and shifting.
• Hidden zipper offers a clean silhouette and easy cover removal.

How do I care for these cushions to maximize life and appearance?

Spot-clean spills promptly with mild soap and water to protect the waterproof laminates and fabric finish. For deeper cleaning, remove covers using the hidden zippers and follow the care instructions; store cushions indoors or under cover during extended wet or freezing periods to preserve the foam integrity.

• Spot clean with mild detergent and soft cloth.
• Remove covers via hidden zipper for deeper cleaning when allowed.
• Store in dry location during prolonged rain or snow seasons.
• Avoid machine-drying foam inserts to prevent damage.
