Quick answer: Dacron wrap is a layer of polyester batting wrapped around a cushion's foam before it goes into the cover. It softens the top of the seat, rounds the corners and edges, and helps the foam fill the cover so it looks plump rather than boxy. It adds about 1 inch to the cushion. Add it for sofa seats and backs, deep seats and anywhere you want a softer, fuller look; leave it off for thin dining pads and crisp, tailored cushions.

If you have ordered custom cushions, you have probably seen "Dacron wrap" as an option and wondered whether it is worth it. Here is what it is, what it changes, and when to choose it.

What is Dacron?

Dacron is a brand name for polyester fiber. In upholstery, "Dacron wrap" has become the everyday name for a sheet of polyester batting (a soft, fluffy fiber layer) wrapped around the foam inside a cushion. You may also see it called a fiber wrap or polyester wrap.

The wrap goes over the top, bottom and front of the foam, between the foam and the fabric cover. You don't see it once the cushion is zipped up, but you can feel and see what it does.

What Dacron wrap does

Foam only Foam with Dacron wrap
Look Crisp, squared edges Softer, rounder edges and a fuller "crown"
Feel The foam's own firmness right at the surface A softer first touch, with the same foam support underneath
Fit in the cover Can look boxy or slightly loose at the corners Fills the cover, so the fabric sits smoother
Thickness The foam thickness you order About 1 inch more

Dacron wrap does not change the foam itself. A firm foam is still firm underneath; the wrap only softens the top layer and the edges. If a cushion is too hard, choose a softer foam first, then add the wrap. Our cushion thickness and foam guide compares each foam.

When to add Dacron wrap

  • Sofa and loveseat seat cushions. Many original sofa cushions have a fiber wrap, so adding it helps replacements match the rest of the sofa. See replacement couch cushions.
  • Back cushions. The wrap gives backs a softer, more relaxed shape.
  • Deep seat outdoor cushions. A fuller, lounge-style look on deep patio sofas. See deep seat cushions.
  • Covers that feel slightly loose. When you keep an existing cover and order new foam, the wrap helps the foam fill it.

When to leave it off

  • Thin dining chair pads. On a 1–2 inch pad, an extra inch changes the seat height noticeably. See best dining chair cushions.
  • Crisp, tailored looks. Window seats, banquettes and benches often look best with sharp, square edges.
  • Cushions that get soaked. Polyester fiber doesn't absorb much water itself, but a batting layer can hold moisture between its fibers. On cushions left out in heavy rain, bare Dry Fast foam drains and dries fastest.

How Dacron wrap changes measuring

Because the wrap adds about 1 inch, it matters how you measure:

  1. Ordering a complete cushion: measure the seat or your old cushion as usual and add the wrap as an option. The cover is sewn to suit.
  2. Ordering foam for a cover you already have: measure the inside of the cover seam to seam. If you add Dacron wrap, we allow for the extra inch so the insert fills the cover without straining the zipper.
  3. Matching an old cushion: unzip it and check whether there is a fiber layer around the foam. If there is, add the wrap to your new one so it looks the same.
