Outdoor Pillow Inserts 20x20 Pack of 2 - Waterproof, Supportive

Our review of these 20 x 20 outdoor pillow inserts finds them best suited for patios and seasonal outdoor seating where water resistance and washable covers matter. The boldest reason to buy is the waterproof cover combined with a supportive 100% polyester fill that keeps cushions comfortable for casual outdoor lounging. They arrive vacuum-packed and need a bit of hands-on reshaping, but for someone who wants inexpensive, durable pillow cores to tuck into decorative covers, these inserts deliver reliable performance.

Key Features

• Pack Size: Two 20 x 20 in inserts provide an immediate matching pair for a sofa, loveseat, or outdoor bench.
• Waterproof Cover: The outer cover resists moisture for better outdoor durability and reduces the risk of water damage to the fill.
• Polyester Fill: Filled with 100% polyester for a balance of softness and support that holds shape under normal outdoor use.
• Hidden Zipper: The concealed zipper allows adjusting the amount of fill to customize loft and comfort level.
• Multiuse Design: Sized and styled to work on patio furniture, garden chairs, sofas and beds, indoors or out.
• Vacuum Packed: Ships compressed and will fluff back up after pressing and squeezing to restore loft.

Who It's For

These inserts are a good match for homeowners who rotate seasonal covers on patios or who want a waterproof core that can handle occasional exposure to damp conditions. They work well for renters, people refreshing balcony furniture, or anyone needing a coordinated pair for outdoor seating.

They are less suitable for heavy-duty commercial outdoor seating or for users who expect permanent exposure to rain without removing the pillow core from wet covers; the manufacturer recommends keeping the core dry to prevent moisture-related damage.
