The Sonoro Kate is a 2-inch queen mattress pad with a bamboo cover and down-alternative fill, sold as a cooling, extra-thick topper. It weighs about 10 pounds and has a medium feel, so it adds softness without swallowing you like a deep memory-foam topper. The best new price is $13.99 at eBay as of November 6, 2026, far below what a 2-inch bamboo pad usually costs, so check that listing carefully before buying.

Owners are split: many like the softness and the cool bamboo surface for the money, while others say it flattens and does not stay cool through the night.
