Is the cushion foam wrapped in Dacron, or is it just a bare block?

Also asked as:Are your cushions Dacron wrapped?Do you wrap the foam with anything?

Buyers squint at a cushion photo and ask what's under the fabric. Fair question, partner. Here is the cross-section, layer by layer.

The quick answer

No, the cushion foam is not a bare block: it is wrapped in polyester fiber (Dacron) wadding before it goes into the cover. The wrap fills the cover out, softens the surface and rounds the edges, while the firm high-resilience core, about 2.0 lb/ft³ (32 kg/m³), does the supporting. Daybed set cushions and pillows are built the same way.

Key facts

  • The foam core is wrapped in polyester fiber (Dacron) wadding; it is not a bare block.
  • The wrap goes on before the foam enters the cover.
  • The wrap fills out the cover, softens the surface and rounds the edges.
  • The core is high-resilience foam at about 2.0 lb/ft³ (32 kg/m³), firm to medium-hard.
  • Daybed set cushions and pillows use the same wrapped foam.
  • A softer 28-density foam, about 1.75 lb/ft³ (28 kg/m³), can be asked for instead.

Dacron wrap and foam core: two layers, two jobs

A block of foam off the cutter has flat faces and hard 90° corners. Wrap it in Dacron before it goes into the cover and three things change: the cover fills out, the surface softens, the edge rounds over.

What the wrap doesn't do is hold you up. The wadding decides how the cushion feels at the surface; the foam decides how it feels an hour into a long dinner.

The same build goes into bench cushions and daybed sets, and the foam firmness finder compares the densities. The Pattern on why cushion foam is wrapped goes deeper.

A foam cushion with no wrap has hard square corners. Wrapped in polyester fiber first, the same 32-density core comes out full and rounded.

Buyer questions

  1. A common question

    Which foam do you use, how firm is it, and is it wrapped?

    The workshop's answer

    High-resilience foam at about 2.0 lb/ft³ (32 kg/m³), firm to medium-hard, so you don't sink in. It is wrapped in polyester fiber (Dacron) before going into the cover, which gives fuller, softer edges.

  2. A common question

    What's inside the daybed set cushions and the pillows?

    The workshop's answer

    Firm high-resilience foam wrapped in polyester wadding (Dacron). It supports well, holds its shape and gives a softer surface.

  3. A common question

    Could I have a plusher cushion instead of the firm one?

    The workshop's answer

    Yes. Ask for 28-density foam instead of the standard 32, or add a 3/4 in (2 cm) wadding layer. Feather-wrapped foam and soft draped pads aren't offered.

Questions buyers ask next

What is Dacron on a foam cushion?

Dacron is a polyester fiber wadding. Here it is wrapped around the foam core before the cover goes on, so the surface is a little softer and the edges come out rounded rather than sharp.

Does the Dacron wrap make a firm cushion soft?

Only at the surface. The wrap takes the hard edge off the top and corners, but support still comes from the firm core. For a genuinely softer seat, ask for 28-density foam instead.

Can a thick backrest or bolster use the same foam?

Thick backrests of about 12-14 in (30-35 cm) without tufting use foam, often cut as a wedge. Round arm bolsters suit silicone balls; neck rolls do well with shredded foam.
