OfficeMellow specializes in home office and small business workspace products, including office desks, chairs, storage furniture, monitor and laptop stands, office electronics, cable management, task lighting, shredders, laminators, scanners, docking stations, and related accessories.

Please review the dimensions, weight capacity, mounting requirements, and available clearance listed on the product page. For desks, chairs, cabinets, and mounted accessories, we recommend measuring your room, doorway, desk surface, and installation area before ordering.

Check the product page for supported device models, port types, operating systems, voltage, plug type, monitor size, weight limits, or printer compatibility. Contact us before purchasing if you are uncertain about compatibility.

Many desks, chairs, cabinets, stands, and shelving products require some assembly. Assembly requirements and included hardware vary by product, so please review the individual product description and instructions before purchase and use.

OfficeMellow charges a flat standard shipping fee of $6.90 per eligible order, unless a different charge or delivery restriction is clearly shown during checkout.

Orders are generally processed within 1–3 business days. Estimated delivery within the United States is typically 5–10 business days after shipment. Oversized furniture, split shipments, carrier delays, or high-demand periods may require additional time.

Products may be stored in different warehouses or shipped in multiple boxes. As a result, items and furniture components may arrive separately with different tracking numbers. Please review all shipping confirmation emails before reporting an incomplete delivery.

Please contact us as soon as possible after placing your order. We will make a reasonable effort to update or cancel an order that has not entered processing or shipment, but changes and cancellations cannot be guaranteed once fulfillment has begun.

Eligible products may generally be returned within 30 calendar days of delivery, subject to our Return & Refund Policy. Items should be unused, unassembled, uninstalled, and returned with their original packaging, hardware, manuals, and accessories. Contact us for authorization before sending a return.

Contact us within 7 calendar days of delivery whenever reasonably possible. Include your order number, a description of the issue, and clear photographs of the product, packaging, shipping label, and affected components. Please retain all packaging until the claim has been reviewed.
