Mattress Shipping Cost from Oslo to Riga

To ship a mattress, first protect it with a waterproof mattress bag and bubble wrap, then vacuum seal to compress if possible, place it in a sturdy, correctly-sized cardboard box, secure tightly with tape, and compare courier/freight services like FedEx, UPS, or specialized movers ( uShip, Pak Mail ), considering options like pallet delivery or white-glove service for large items and comparing costs.

Very generally, your national postal service will be the cheapest way to ship internationally. The Universal Postal Union has been in place since 1874 reliably transferring documents and goods to over 190 nations. One interesting sidelight.
