Siena 10" Signature Memory Foam review

Siena's 10-inch Signature mattress answers the cheapest-but-good question better than anything else we compared. A queen cost $329 on Siena's US store when we checked, and that price comes with terms that budget brands often skip: a 180-night home trial, free shipping and returns, and a 10-year warranty under which Siena says it will repair or replace any defect for free. The build is simple. Four layers include a breathable top fabric, 2 inches of contouring memory foam, a stability foam layer and a durable outer cover. The foams are CertiPUR-US certified and Siena says the construction is fiberglass free. Siena also offers a 30-day price match guarantee. The trade-off is depth: 2 inches of memory foam is a thin comfort layer, and the all-foam design gives less bounce and edge support than the hybrids further down this list. Buyers who want more cushioning can step up to the 12-inch Signature for $50 more.
