Polyfill Stuffing Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Poly-Fil is the best-performing polyfill stuffing brand in July 2026, moving 26,000 units across 5 ASINs for 84.1% of Top 10 volume. Jecqbor follows with 2,000 units (6.5%), ahead of Welacer on 1,900 units (6.1%).

With 4 brands splitting the Top 10 and 96.8% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $20.49 to $28.21, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B07CBQ8ZJ3 booked 1K units at $61.44, with ▲ 25.0% MoM change. On the growth side, B0CFQTC771 leads positive momentum with ▲ 300.0% MoM growth on 200 units, with B0GWQ6YL5D close behind at ▲ 200.0% MoM on 300 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
