Buying Guide: Navy Outdoor Pillows
- Size and fit: Choose pillow covers that fit your inserts snugly. Most 18×18 or 20×20 inch covers pair with standard inserts; note that some listings specify slightly smaller covers to ensure a tight fit.
- Waterproof vs. water-resistant: For damp climates or poolside use, prioritize waterproof fabrics with coatings to prevent moisture absorption. If placement is under a covered area, water resistance may suffice.
- Inserts included or not: Some products include inserts, which affects overall cost and time to decorate. If inserts are not included, plan for separate purchases.
- Color longevity: Navy hues can fade with prolonged sun exposure. Look for UV protection or fade-resistant materials when possible.
- Care and maintenance: Machine-washable covers simplify cleaning. Check zipper quality and ease of removal for replacing inserts or washing.
- Pattern and texture: Solid navy offers versatility and compatibility; patterned backs or fronts can alter how the set reads visually in a space with varied furniture.
- Durability vs. cost: More durable fabrics (polyester with protective coatings) generally cost more but last longer in outdoor environments. Balance budget with expected exposure and usage.
- Coordinate with existing decor: Consider furniture tones (tan, white, wood, rattan) and other textiles like outdoor rugs and throws to create a cohesive look.
