I am really disappointed with the service. I must say that national matress customer support staff are useless. They don't even know their own policies. Peter better learn more about your policies. Requested a return/exchange on a product and I received an email stating it's not possible. Then another member of the customer team sent a review request 2 weeks after the exchange eligible date and acknowledged the issue but clearly stating that they won't do anything about it. Even though we clearly initiated the process within the eligibility period. I simply can't trust the service.
