We aim to deliver your order within 2–5 business days for most Melbourne metro areas, including Melbourne CBD, western suburbs and surrounding regions, and 4–7 business days for rural or regional locations across Victoria from the date it’s shipped. Please allow up to 14 business days in case of minor freight delays.
Shipping timelines depend on product availability. Items stocked in our Laverton North warehouse can often be dispatched sooner, while custom-made furniture in Australia may require 3–4 weeks for production before dispatch.
Delivery times may be affected by peak holiday periods, extreme weather, flooding, bushfires, or other external factors. For regional Victoria and interstate areas, local couriers complete the final delivery, which may add additional time.
If you require urgent delivery within Melbourne, please call us or use our Contact Us form. Our team can confirm stock availability and provide a more accurate delivery estimate before you place your order.
These timeframes are based on average estimates from our trusted carriers, and we’ll always aim to deliver your order as quickly as possible.
