There are advantages and disadvantages of packing inside furniture items
Advantages:
1) Reduced overall volume
2) Protection of fragile items i.e. crystal. (Rather than casing can pack and secure inside furniture)
Disadvantages:
1) Weight increases, making handling more difficult. Potential damage due to dropping.
2) Movement of items during transit. If items can move in recess area, drawer area etc - damage to internal packed item, and furniture can occur.
3) Displacement - if furniture item is stowed on it`s side, or upside down - internally packed items disperse. (Potential damage)
4) Customs inpection. - in the event of customs inspection, costs associated with unwrapping, re wrapping furniture items are more expensive.
Recommended tip: If packing inside furniture, ensure items cannot move in transit, and pack light items rather than heavy items.
