Buying Guide: Key Considerations For Patio Pillow Purchases
Shape and size alignment matters. An 18×18 inch insert typically fits standard covers, but ensure your inserts are slightly larger or the cover slightly smaller to achieve a full look without gaps.
Water resistance and filling
Choose waterproof or water-resistant fabrics for covers when possible. Inserts with high-quality 7D fiber fill help maintain shape and comfort after exposure to outdoor elements.
Coverage vs inserts
Decide between buying pillow covers, inserts, or a full pillow set. Covers offer styling flexibility; inserts provide shape and plumpness; full sets simplify matching and setup.
Durability and maintenance
Look for covers with hidden zippers for easy cleaning. Consider fabrics that resist fading and mildew, especially for sun-exposed patios and poolside seating.
Color and pattern coordination
Neutral tones pair with bold accents, while floral or patterned covers add focal interest. Ensure the colors complement your existing furniture and decor style.
Care and compatibility
Check washing instructions and confirm insert sizes. In outdoor spaces with wind or heavy use, choose heavier fills to reduce flattening and shifting.
