Polysleep makes foam mattresses in Montreal, including its Origin, Luna, Sierra, Aura and Zephyr ranges, and also sells pillows and other sleep accessories.
Mattresses of cellular plastics are HTS 9404.21.00, which the White House added to the Section 338 list in the Annex II insert list of September 8, 2026, so from 12:01 a.m. eastern time on September 15, 2026 every Polysleep mattress crossing into the United States carries a 50% duty on top of the price. Polysleep sells into that market itself and ships the goods over the border rather than out of an American warehouse: its own FAQ says "We currently ship to all Canadian Provinces and Territories, but also to all the United States" and "Our mattresses are shipped from our facility in Montreal, Canada." Polysleep has published nothing about the measure.Source: whitehouse.gov, Sep 8, 2026
Made in Canada
Polysleep says its mattresses are made in Montreal and that it formulates and produces its foam in-house. Its US FAQ says mattresses ship from its Montreal facility.
On the tariff list
- HTS 9404.21.00 · Mattresses made of cellular rubber or plastics, whether or not covered · 50% since Sep 15, 2026
Every mattress in the catalogue is poured foam. The shop's own copy describes "a top layer of ventilated viscoelastic hybrid foam that promotes air circulation" over a "base layer—that also acts as a boxspring and is made of high-density foam", and the Made in Canada page says "every mattress we make is crafted right here in Canada at our facility in Montreal, Quebec". A mattress of cellular plastics is HTS 9404.21.00, one of the subheadings the White House Annex II of September 8, 2026 inserts into the Section 338 list effective September 15, 2026.
Rates are the additional US duty under Section 338. About the tariffs
