US buyer tip

Mattress sales peak on Presidents Day, Memorial Day, Labor Day and Black Friday; check whether the trial and returns apply when you buy on Amazon.

Prices on Amazon.com move in a pattern. The deepest cuts land on Prime Day in July, Prime Big Deal Days in October and the Black Friday to Cyber Monday week, with smaller drops around Presidents Day, Memorial Day, the Fourth of July and back-to-school. Judge a deal against the usual price we show, never against the crossed-out list price.
