We do charge for shipping to Alaska, Hawaii, US Territories, and International Shipments, which is quoted on an order-by-order basis.

Please contact our Haiku Concierges at our toll-free number, and we’re happy to help. Check out our Shipping Made Simple blog post or our Shipping Information page.

Returns and Cancellations

Most of our customers love our products at first sight, but if you change your mind or don’t like a product, we can cancel most orders up to the point they ship. Products in new, unopened, resalable condition can also be sent back in original packaging materials, but the customer is responsible for the return shipping/freight charges, per our Return Policy. Lastly, Custom Made and Made-to-Order items must be cancelled within 72 hours or are charged in full to start the production, at which point, they can’t be cancelled or returned. Please contact our Haiku Concierges at our toll-free number if you have questions.

Warranties

Our catalog of furniture items is high quality and made to last. All furniture items are sold with a 1-year manufacturer’s warranty against defects in craftsmanship or functionality per our Return Policy.
