Quince Premium Down Alternative Duvet Insert review

Quince's Premium Down Alternative Duvet Insert is the cheapest product in this list at $99.90, and it is the one to buy if price comes first or if down is not an option. Quince encases ultra-fine hypoallergenic microfibers in a smooth cotton shell, and offers the insert in Lightweight, All-Season and Ultra-Warm versions across Twin, Full/Queen and King/Cal King sizes. Shipping is free and returns are accepted for 365 days, which is the longest window here alongside Brooklinen and the Quince down insert. The product page lists 6,181 reviews. What Quince does not publish is a fill weight or fill power equivalent, so it is harder to compare with the Buffy Cloud, which states 300 gsm and a 700 fill power equivalent. A synthetic fill also tends to need more bulk than down for the same warmth. For a guest bed, a dorm or a first apartment, the price and return terms make it an easy low-risk pick. We compared documented features and published prices and did not run sleep tests.
