Pillow Inserts: A Wholesale Guide to Fills, Loft & Firmness

Pillow Inserts: A Wholesale Guide to Fills, Loft & Firmness

Pillow feel is not 'soft' or 'firm' — it is fill type, loft, firmness and fill weight in grams. Here is how a wholesale buyer specs pillow inserts by sleeper and market, and writes a tech pack a factory can fill to.

The spec that actually controls how a pillow feels is not the word 'soft' or 'firm' — it is the fill type, the loft (height), the firmness, and the fill weight in grams that the factory fills to. Match those to the target sleeper and market and a pillow program becomes reproducible. The one insight to build a range around: as you move from stomach to back to side sleeping, the pillow needs more loft and more firmness, because the gap between head and mattress grows.

The fills, and how they behave

Each fill trades feel, support, breathability, washability, allergy performance, durability and cost differently. Solid memory foam contours firmly but sleeps warm; shredded memory foam adds airflow and adjustable loft; down is soft and lofty but low on support; feather is springier and cooler; microfiber and gel fiber are the washable, hypoallergenic down-alternatives; latex is firm, responsive and very durable.

Pillow fills compared — feel, care and best sleeper.

Loft and firmness by sleep position

This mapping is the buyer's most useful tool. Loft is commonly banded as low (under 3 in / 7.6 cm), medium (3–5 in / 7.6–12.7 cm) and high (over 5 in / 12.7 cm), with broad-shouldered side sleepers needing 6 in / 15 cm or more.

StomachLow (under 3 in)Soft to mediumSoft down, low-fill microfiber
BackMedium (3–5 in)Medium / medium-firmMemory foam, feather, gel fiber
SideHigh (over 5 in; 6 in+ broad shoulders)Medium-firm to firmFirm shredded foam, latex, high-fill
CombinationMedium, adjustable preferredMedium-firmAdjustable shredded foam or latex
Sleep position drives loft and firmness — the neck gap to fill grows stomach to side.

Firmness and loft are delivered by fill weight in grams, which is the enforceable order line. As a rough guide a Standard insert runs from a few hundred grams of down for a soft pillow up to about a kilogram for a firm microfiber or latex one — treat published grams as ranges and confirm against a physical sample, because the same grams behave differently by fill and size.

Bed styled with several sleeping pillows of different loft
A pillow program is specified by fill, loft band, firmness and fill weight per size — including Euro squares for European accounts.

Sizes — and why Euro squares matter

Cut to the destination market: Standard around 50 x 66 cm (20 x 26 in), Queen around 50 x 76 cm (20 x 30 in), King around 50 x 92 cm (20 x 36 in). European accounts also use Continental square pillows — 65 x 65 cm (26 x 26 in) and 80 x 80 cm — as actual sleeping pillows, not just decoration, and UK sizes differ slightly. Cut the insert 2–5 cm larger than any pillow sham so it fills the corners.

Shell and certifications

For down and feather, the shell must be a downproof cotton — a tightly woven, calendered cambric around 230–330 thread count with double-stitched seams and piping — or fine fill beards through. Require OEKO-TEX STANDARD 100 on fill and shell, CertiPUR-US on any foam, the Responsible Down Standard (RDS) on down and feather, and FTC-compliant fiber-content and down labeling for the US market, plus a fill-composition test and a market flammability check.

How to spec a pillow order

From sleeper to accepted bulk

  1. 01

    1 · Choose fill by target sleeper and price

    Map the SKU's intended buyer and price tier ($ microfiber to $$$$ down) to a fill from the comparison table.

  2. 02

    2 · Set loft, firmness and fill weight

    Pick the loft band and firmness from the position table, then convert to fill weight in grams per size — for down, also state fill power. This grams figure is what the factory fills to.

  3. 03

    3 · Pick sizes, incl. Euro for the EU

    Specify finished sizes and cut the insert 2–5 cm larger than the sham; include 65 x 65 cm and 80 x 80 cm squares for European accounts.

  4. 04

    4 · Choose the downproof shell and cover

    For down/feather, require downproof cotton around 230–330 TC with double-stitched seams and piping; select the cover fabric and add a gusset where stable loft is needed.

  5. 05

    5 · Require certifications and test, then sample

    Mandate OEKO-TEX, CertiPUR-US (foam), RDS (down) and FTC labeling, add a fill-composition test, and approve a pre-production sample — weigh the fill, measure loft, check for leakage — before bulk.

Never order a pillow on 'medium firm.' Order it on a fill, a loft band, and a fill weight in grams per size — those three make the feel reproducible batch to batch.

Frequently asked questions

What single spec controls how firm or high a pillow feels?
Fill weight in grams for that size (plus fill power for down). 'Soft' and 'firm' are subjective; grams is what the factory fills to. Always quote fill weight per size, because the same fill needs more grams in a King than a Standard for equal loft.
How do I stop feathers or fiber poking through?
Specify a downproof, calendered cotton shell around 230–330 thread count with double-stitched seams and piping. Match the weave to the fill — very fine down needs a tighter shell; pure feather benefits from a durable weave that resists quill punch-through — and require a leakage check on the pre-production sample.
Which loft and firmness suit each sleeper?
Stomach sleepers want low loft (under 3 in) and a soft-to-medium feel; back sleepers want medium loft (3–5 in) and medium-firm; side sleepers want high loft (over 5 in, or 6 in-plus for broad shoulders) and firm. The neck gap to fill grows from stomach to side, so loft and firmness rise with it.
What sizes should a European program carry?
Beyond Standard, Queen and King, European accounts use Continental square pillows — 65 x 65 cm (26 x 26 in) and 80 x 80 cm — as real sleeping pillows, and UK dimensions differ slightly. Confirm each account's finished sizes and cut inserts 2–5 cm larger than the shams.
Which pillows can we market as machine-washable?
Only the microfiber, gel fiber, polyester-cluster and cover-only shredded-foam lines. Down, feather, solid memory foam and latex should be labeled spot-clean or dry-clean; mislabeling washability is a returns and FTC care-labeling risk.
