Best Room Darkening Curtains Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
NICETOWN is the best-performing room darkening curtains brand in July 2026, moving 24,000 units across 2 ASINs for 29.6% of Top 10 volume. MIULEE follows with 23,000 units (28.4%), ahead of ChrisDowa on 10,000 units (12.3%).
With 7 brands splitting the Top 10 and 70.4% 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 $10.98 to $16.50, which frames the price band a competing listing has to justify.

Trending Room Darkening Curtains Products — Growth Leaders & New Top 10 Entrants
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: B0BY26JWX7 booked 5K units at $19.99, with ▲ 66.7% MoM change. On the growth side, B07C9HL1G1 leads positive momentum with ▲ 100.0% MoM growth on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
