We provide standardized, customer-centric return and exchange services for all bed sheet, duvet insert and blanket household bedding products, offering a 30-calendar-day return and exchange window calculated from the official order delivery date. To qualify for return or exchange, all submitted items must remain completely unused, unwashed, unstained, unfolded and undamaged, retaining original brand-new condition with no body contact traces, washing marks, dust contamination, artificial damage or extrusion deformation. All original factory packaging, including dust-proof films, moisture-proof outer bags, compression packaging bags, product labels and instructional manuals, must be fully intact without loss, damage or disassembly traces. Custom personalized sized bedding, privately dyed or modified products and final sale clearance items are strictly non-returnable and non-exchangeable due to customized attributes and special promotional sales regulations. As close-fitting household textile products with strict hygiene standards and secondary sales restrictions, any bedding that has been laid for use, cleaned, washed, stained by sweat and dust, artificially cut and modified or improperly stored is ineligible for return and exchange. Bed sheets with permanent wrinkles and dirt stains, duvet inserts with flattened fluffiness and filling displacement, and blankets with fiber shedding, extrusion deformation and usage traces will be rejected for return applications to uphold unified product hygiene standards, quality performance and fair shopping experiences for all customers. To initiate a return or exchange request, users must submit an application via the official website portal with a valid order number and detailed problem description. After professional team review and approval, customers will receive an official return authorization number and standardized return shipping guidelines. Customers bear full responsibility for all return shipping fees and transportation risks unless the product has manufacturing defects, confirmed transit damage, warehouse shipping errors or missing factory accessories attributable to our team. We strongly recommend using trackable logistics services and fully restoring original dust-proof, moisture-proof and compression-resistant packaging during return shipment to prevent secondary contamination, crease deformation and fluffiness loss that invalidate return eligibility. After receiving and inspecting returned products to confirm full compliance with official return standards, we will process refunds or store credit exchanges within three to five business days. All refunds are issued via the original payment channel, with final arrival time dependent on the corresponding financial institution’s processing efficiency. Direct exchanges for different sizes, colors or styles are not available; qualified returned items can only be converted to store credits for subsequent purchases. For unresolved return and exchange inquiries, users may refer to the official FAQ page for detailed professional guidance and after-sales support.
