Items in stock in the UK will normally take up to 14 days. Sometimes it can take longer depending on your postcode and your availibality to receive the furniture.
Items made to order and not in stock in the UK (this will be most items) will take around 16 weeks which includes production and shipping from Indonesia to the UK.
Although this is quite a long time it does mean you have a large choice of models and finishes. In addition there is the facility to alter sizes to suit. On some occasions this might even save you time when you consider the large amount of time and effort that can go into researching and sourcing the exact piece required.
