Items are shipped "FOB Destination" to the 48 contiguous states.
Most items ship via FedEx, but larger pieces of furniture or mattress foundations must be shipped via common carrier. Common carriers are typically only responsible for getting the items off their truck, and do not have any requirement to help you carry the item inside. So if you are receiving a large item, have help on-hand. Or you may also purchase "white glove" service which will authorize the transportation company to help get the product into its desired location (within reason) and assemble it.
