Firm Mattress Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

EGOHOME is the best-performing firm mattress brand in July 2026, moving 30,000 units across 4 ASINs for 54.5% of Top 10 volume. Graco follows with 9,000 units (16.4%), ahead of Letmxiu on 5,000 units (9.1%).

With 6 brands splitting the Top 10 and 80.0% 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 $66.49 to $177.49, 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, 2 ASINs forced its way in: B09KP58856 booked 3K units at $109.00, with ▲ 50.0% MoM change. On the growth side, B0FVF5Q6J3 leads positive momentum with ▲ 600.0% MoM growth on 700 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
