Freight Class for Packaged Mattresses

The Billion-Dollar Compression Shift

For bedding ecommerce brands, the "bed-in-a-box" revolution wasn't just a marketing win—it was a logistical miracle. Traditional inner-spring mattresses and box springs are the definition of "shipping air." They are bulky, fragile, and have extremely low density, often resulting in Freight Class 250 or 300. By contrast, modern memory foam mattresses are vacuum-sealed and mechanically compressed into compact cartons, dramatically increasing their Pounds per Cubic Foot (PCF) and lowering their freight class.

Mechanically Altering PCF for Profit

In the bedding industry, your "package engineering" is your pricing strategy. When you mechanically compress a mattress, you are fundamentally changing its **Pounds per Cubic Foot (PCF)** profile. Carriers reward this efficiency because compressed mattresses can be stacked and occupy far less linear feet of a trailer. However, you must still provide exact measurements. If a carton "bulges" due to poor compression, an automated dimensioner will recalculate the volume, potentially bumping you back into a higher class.

Bedding Shipping Standards

• Carton Footprint: Avoid oversized cartons. Any "movement space" inside the box is wasted volume the carrier will charge you for.
• Weight Accuracy: Memory foam is heavier than most expect. Use a certified scale and include the pallet weight in your LTL quotes.
• Density Verification: Use our calculator to see the exact PCF shift between your raw and packaged product states.
