Pillowflex Premium Polyester Pillow Insert 15x15 (Pack of 2) — Soft Lofty Support, Machine-Washable

Pillowflex 15x15 Premium Polyester Pillow Insert (pack of 2) is a soft, supportive square pillow insert designed to give decorative shams a full, plump look while staying machine-washable and made in the USA.

Refresh your sofa, bed, or favorite chair with these 15x15-inch pillow inserts from Pillowflex. Built with a polyester-cotton blend shell and sustainably sourced polyester fill, they balance softness and structure to keep covers looking tailored and comfortable. The inserts come as a pair, are easy to care for, and are sized to pair with shams for a full appearance when you choose an insert slightly larger than the cover.

How do these inserts help my throw pillows look fuller?

These inserts are intentionally lofted so decorative pillow covers sit taut and maintain a square shape instead of collapsing. Choosing a slightly larger insert than your cover results in a plump, tailored finish that elevates the entire room.

• 65/35 polyester-cotton blend shell for stable shape
• Plush polyester fill offers loft without flattening quickly
• Ideal to use slightly larger than the sham for a full look

Are they comfortable and supportive enough for everyday use?

Yes — these inserts are soft to the touch while providing enough internal support to cradle your head or back briefly. They balance cushiness and structure so they work well both as decorative pieces and for occasional lounging.

• Soft, cloud-like feel paired with resilient fill
• Maintain loft through normal daily use
• Good for back support during casual sitting

What care is required to keep them fresh and long-lasting?

Pillowflex inserts are machine washable and odorless, simplifying routine care. Washing on a gentle cycle and air-drying or tumble-drying on low will keep the inserts clean and help preserve loft and fabric integrity.

• Machine washable for easy cleaning
• Low-heat tumble dry or air-dry to retain loft
• Odorless fill and fabric for immediate use after washing

How do I choose the right size insert for my pillow cover?

For the most attractive result, select an insert slightly larger than your pillow cover so the fabric stretches smoothly across the surface. Refer to the sizing chart image to match your sham size; for example, pair a 15x15 insert with a 14x14 or similar cover for a plump finish.

• Use sizing chart to compare insert and cover dimensions
• Choose an insert larger than the cover for fuller appearance
• Pack of 2 offers easy matching for pairs of shams
