We do not offer Free Shipping as a standard policy. However, we do offer Free Shipping on the First Exchange exclusively for small items (apparel and accessories).

🔄 2. Returns & Exchanges
Do mattresses have a Sleep Trial?
No. We do not offer a Sleep Trial period. We accept mattress returns only if they are sealed in their original packaging. Once opened or unrolled, mattresses are considered personal-use items and are Final Sale (non-returnable).
Important: Please ensure you verify comfort levels and other details with your Independent Consultant before purchasing.
Is there a fee to return a mattress?
Yes. If you return a mattress (which must be sealed/unopened), a 10% Restocking Fee will be deducted from your refund amount to cover handling and operational costs.
How do I initiate a return?
It is simple and automated. Please visit our Returns Center at
https://eenergybynipponflex.aftership.com/returns. Enter your order number and email to follow the instructions.
Can I return Custom items?
No. Products made to order, including items with special sizes or specific energy/comfort adjustments requested by the customer, cannot be returned or exchanged.
I bought from a Distributor. Can I return it here?
No. If you purchased your product through an Independent Distributor, you must contact them directly. Nipponflex USA only processes returns for orders placed directly on our official website, e-energyusa.com.
