How to Choose the Best Throw Pillow Inserts

Choosing the Right Insert

Selecting the ideal throw pillow insert involves considering a few key factors to ensure both comfort and aesthetic appeal.
  • Size Matters

    The insert should be 1-2 inches larger than your pillow cover in both dimensions (width and height). This slight size difference allows the cover to fill out completely, creating a plump, luxurious look. For example, a 20x20 inch cover would best suit a 22x22 inch insert. Using an insert that is too small will result in a saggy, unappealing pillow.
  • Fill Material and Loft

    The type of fill significantly impacts the insert's feel and durability. Polyester fiberfill is a common, affordable option that offers good loft but can compress over time. Down or down-alternative fills provide a softer, more malleable feel and are excellent for achieving that coveted 'karate chop' look. Consider your preference for firmness and how you'll use the pillows when making this choice.
  • Durability and Maintenance

    Look for inserts with a durable casing, often made of cotton or a poly-cotton blend, to prevent fill from escaping. Some inserts are machine washable, which is a convenient feature for easy care. For long-lasting inserts, consider those with reinforced stitching and high-quality fill that resists clumping or flattening.

Frequently Asked Questions

What is the difference between down and down-alternative inserts?
Down inserts are made from the soft undercoating of waterfowl, offering a luxurious, compressible feel. Down-alternative inserts mimic this softness using synthetic materials like polyester fiberfill, making them a hypoallergenic and often more budget-friendly choice.
How do I choose the right size insert for my pillow cover?
It's generally recommended to choose an insert that is 1-2 inches larger than your pillow cover in both width and height. This ensures the cover is fully filled, providing a plump and well-shaped pillow that looks its best.
Can I wash pillow inserts?
Many pillow inserts, especially those made with polyester fiberfill, are machine washable. Always check the manufacturer's care instructions before washing to ensure proper cleaning and to avoid damaging the fill or casing.
What does 'loft' mean in relation to pillow inserts?
Loft refers to the thickness or height of the pillow insert when it's fully fluffed. Inserts with higher loft will create a plumper, more substantial-looking pillow, while lower loft inserts will result in a flatter appearance.
