According to Sleep Country, customers can send back their products to the store for an exchange or return within the first 100 nights after purchase. But like the process by which you return a mattress to Amazon, customers can also contact Sleep Country to help ship it back to the store.
Also, for those who will be returning the products, refunds or balances that remain following an exchange will be refunded to the customer.
However, shipping fees (for the initial order) will be deducted from this refund. But if there is a balance due to you after products not similar in price or type are exchanged, customers will need to pay up.
