Oubonun 12 x 20 Waterproof Lumbar Pillow Inserts — Set of 4, Polyester Fill & Hidden Zipper

Oubonun 12 x 20 lumbar pillow inserts are waterproof, supportive cushions made for both outdoor and indoor use, sold as a set of four to refresh patio seating with weather-ready comfort.

Bring durable comfort to your outdoor seating with these Oubonun waterproof lumbar inserts. Each 12 x 20-inch pillow is filled with resilient polyester and sheathed in a water-resistant cover designed to stand up to splashes, light rain, and everyday patio use. The hidden-zipper design lets you fine-tune loft and firmness, while the practical vacuum-packed shipping keeps the set compact until you restore the fluff by hand. These inserts pair easily with decorative cushion covers or work alone to add back support to benches, chairs, and sofas.

How do these inserts hold up outdoors?

They use a water-resistant outer layer that helps shed moisture and makes cleaning easier than standard indoor fills. The polyester interior resists flattening and keeps lumbar support even after repeated use.

• Waterproof outer fabric for splash and spill protection
• Polyester fill that maintains loft and shape
• Machine-friendly surfaces for quick spot cleaning

Can I adjust the firmness to suit my cushions?

Yes — each insert has a concealed zipper so you can remove or add fill to reach preferred support levels. That flexibility makes these inserts versatile for different cushion covers and seating types.

• Hidden zipper for a clean look and simple access
• Removable filling allows custom loft and firmness
• Works with standard 12 x 20 decorative covers

What care steps should I follow to keep them looking their best?

These inserts arrive vacuum-compressed and need a little manual reshaping after unpacking. Avoid machine washing the insert itself; spot-clean the cover and hand-wash if necessary to preserve the waterproof finish and loft.

• Vacuum-packed for compact shipping—knead and shake to restore fullness
• Hand-wash only to protect the waterproof coating and fill
• Spot-clean stains promptly to prevent set-in marks

Where will these lumbar pillows work best?

They’re designed for flexible use across outdoor furniture and indoor accents. Use them on patio benches, garden chairs, sofas, and beds to add both style and lumbar support without worrying about brief exposure to damp conditions.

• Ideal for patio furniture, porch swings, and poolside seating
• Also suitable inside for accent cushions on sofas or beds
• Set of four lets you outfit multiple seats or create coordinated styling
