16x26 lumbar pillow insert

These lumbar inserts are rectangular and listed at 26 inches by 16 inches (commonly written as 16×26). The listings present the measurement as 26" (length) by 16" (width).

The listings show two fill options: 100% down alternative and a down/feather blend composed of 95% duck feather and 5% duck down.

Care instructions vary by listing. Examples include machine wash and tumble dry, or spot/wipe clean with line dry or lay flat to dry. Check the specific product listing or care label for the exact instructions.

The listed thickness (loft) ranges from about 5.0 inches up to 8 inches across the results.

Cover fabrics shown include woven or plain-weave textiles in either a 65% polyester / 35% cotton blend or 100% cotton.

Both listings specify these lumbar inserts are intended for indoor use.

One listing notes the insert is vacuum-packed. Once removed it will begin to expand — gently fluff it to help restore shape. The insert is also described as double-stitched to reduce seam ripping.
