Furniture & fixtures/Density-rated

Mattress freight class and NMFC guide

Mattresses are bulky and light for their cube, so packed density usually lands in the low single digits. Compression, pallet height, and overhang move the result more than the mattress type.

What drives the class

The density story behind mattresses.

Packed density is mostly a function of compression and pallet height. A loose stack traps air, so the same weight occupies more cube and lands in a lighter, more expensive class. A compressed, tightly wrapped load removes that air and can move several tiers. Overhang and a tall pallet add cube without adding weight, which pushes the result back toward the lighter end. Measure the load you will actually tender, not the best-case stack.

Density-rated. Bedding is generally density-rated. The handling unit, not the mattress label, is what gets measured.

Measure it right

The handling unit is the shipment.

Carriers measure what is tendered, not the product inside the box. Use the pallet, crate, or bundle as the handling unit and include everything that travels with it.

  • Measure the full pallet: mattress stack, pallet deck, wrap, and the widest overhang.
  • Use gross weight, including the pallet, straps, and any protective wrap.
  • Measure each handling unit separately if the pallets are built differently.

The formula

cube = L × W × H ÷ 1,728
density = gross lb ÷ cube

Round for display only. Compare the unrounded density to the scale boundary.

Oversize / bulky

Long, tall, or irregular handling units can affect stowability and linear feet.

High value

Liability limits and securement matter as much as the class.

Moisture-sensitive

Needs wrap, desiccant, or a dry loading position to avoid a damage claim.

Pack it for the rating

Packaging changes the cube before it changes the class.

  • Compression and a tight wrap are the biggest density levers. A loose stack can double the cube for the same weight.
  • Bag or wrap the load so a dry van does not turn a clean mattress into a damage claim.

Don't confuse it with

Adjacent items, different answers.

The most expensive classification mistake is usually a description that sounds close but is not the item. Check these before you copy a description from another shipment.

Box springs and foundations

Bed frames and headboards

Mattress toppers and pads

Before you book

Make the rating defensible.

  • Confirm the current NMFC item for the specific mattress type and packaging.
  • Ask the carrier whether the shipment is rated on the pallet or on individual pieces.
  • Photograph the pallet, wrap, and overhang before pickup for a reclass dispute.

Common questions

Mattresses and the 2025 scale.

How are mattresses classified for LTL freight?

At an estimated packed density of 2–4 lb/ft³, the 2025 density scale spans Class 175–250. That is a planning span derived from the endpoints of the density estimate, not a promise that every shipment lands in every class. The NMFC item and the shipment as tendered control the final class.

What is the classification basis for mattresses?

Density-rated. Bedding is generally density-rated. The handling unit, not the mattress label, is what gets measured.

How do I confirm the NMFC item for mattresses?

Confirm the current NMFC item for the specific mattress type and packaging. Ask the carrier whether the shipment is rated on the pallet or on individual pieces. Photograph the pallet, wrap, and overhang before pickup for a reclass dispute. Confirm the current item in ClassIT+ or with the carrier before booking.

This is an independent planning reference, not the NMFC and not a carrier classification. The typical density is an estimate. The class span is derived from the 2025 density scale. The NMFC item, the carrier tariff, and the shipment as tendered control the final rating.
