The Sonoro Kate is a 2-inch queen mattress topper with a bamboo cover and down-alternative fill, rated medium firmness. It is meant to soften a too-firm mattress and add a cooler-feeling surface. The best new price is $13.99 at eBay as of November 6, 2026, far below what a queen topper of this type usually costs, so check that listing carefully.
