No. Birch mattresses purchased through a retail store do not necessarily include a 100 night sleep trial. Each individual retail partner maintains their own set of return policies. Retail locations are not required to provide a 100 night sleep trial and often offer return policies that differ from the trial period offered through the Birch website. To begin a return or to learn more about their specific return policy, please contact the retail location where you purchased your Birch mattress.
