Freight Class for Furniture
Furniture is one of the bulkier freight types, commonly class 100 to 250. Flat-packed or dense pieces rate lower; assembled, upholstered furniture rates highest.
What is the freight class for furniture?
Upholstered and assembled furniture traps a lot of air, so density is low and class is high. Knock-down (flat-pack) furniture ships much denser and rates far lower. Because the spread is wide, always run the actual dimensions — a single sofa can differ by several classes from a boxed table.
Because freight class is density-driven, there isn’t a single fixed number for furniture — class 100–250 is the common range. Run your actual dimensions and weight below to pin it down.
The widest class range in general freight
Furniture spans more of the NMFC scale than almost anything else that moves LTL — from flat-packed case goods around class 100 to assembled upholstered pieces at 250 and beyond. The spread comes from two independent axes. Construction: a knock-down desk is boards in a slab-flat carton, while the assembled version is the same boards arranged around working-height air. Upholstery: foam and cushioning are engineered softness, which is to say engineered low density, and no packing decision changes what a finished sofa is.
Because the range is so wide, furniture is the commodity where quoting off the category instead of the piece hurts most. "Furniture, class 150" as a standing assumption overbills every flat-packed case-goods shipment and underbills every assembled sofa — the first wastes money quietly, the second gets rebilled loudly. Quote each configuration from its own measured density.
Furniture freight class: worked examples
Density is weight ÷ volume (cubic feet = L × W × H in inches ÷ 1,728). Here is how typical furniture shipments measure out:
Flat-packed desks, palletized — class 100
KD desk cartons stacked 36" high on a 48" × 40" pallet, 380 lb.
48 × 40 × 36 = 69,120 in³ ÷ 1,728 = 40.0 ft³. Density = 380 lb ÷ 40.0 ft³.
9.5 lb/ft³ → class 100 — the favorable end of the furniture range.
Boxed upholstered armchair — class 250
An assembled armchair in a carton, 36" × 34" × 36", 85 lb.
36 × 34 × 36 = 44,064 in³ ÷ 1,728 = 25.5 ft³. Density = 85 lb ÷ 25.5 ft³.
3.3 lb/ft³ → class 250. Upholstery is engineered air — packing can't change it.
One desk, two configurations — class 250 vs class 100
The same desk: assembled in a 62" × 32" × 32" crate at 140 lb, or knocked down in a 62" × 32" × 12" carton at 130 lb.
Assembled: 36.7 ft³ → 140 ÷ 36.7 = 3.8 lb/ft³. Knocked down: 13.8 ft³ → 130 ÷ 13.8 = 9.4 lb/ft³.
Assembled = class 250 · knocked down = class 100. Same product, six classes apart.
Flat-pack arbitrage, and what to do when you can't
For hard furniture the class decision is made at the packaging line, not the loading dock. The same desk ships as an assembled crate at class 250 or as a knock-down carton at class 100 (the worked example above is exactly this pair) — a spread big enough that many manufacturers' entire logistics model is built on never shipping assembled. If your product line allows KD packing at all, it is worth engineering for.
Upholstered and finished pieces that must ship assembled play a different game: protect without inflating. Blanket-wrap-plus-strapping on a skid measures the piece nearly at its own dimensions; a boxed sofa carries carton clearance on all six faces; a full crate adds more still. Each protection tier costs measured cube, so match it to the lane — a one-stop regional move may not justify the crate that a cross-country LTL journey does. Sectionals earn a special note: shipped as separate sections banded upright on one skid, they cube dramatically tighter than one assembled footprint.

How freight class is calculated (density scale)
Freight class is set by density = weight (lb) ÷ volume (ft³). Higher density → lower class → typically lower cost. Volume here is L × W × H × quantity.
| Density (lb/ft³) | Class |
|---|---|
| 50+ | 50 |
| 35 – 50 | 55 |
| 30 – 35 | 60 |
| 22.5 – 30 | 65 |
| 15 – 22.5 | 70 |
| 13.5 – 15 | 77.5 |

Frequently asked questions
What freight class is furniture?
Furniture typically ships at freight class 100–250. The exact class is set by density — weight divided by volume — so packaging and dimensions can move it within that range.
What affects the freight class of furniture?
The main factors are assembled vs. flat-pack, upholstered vs. hard furniture, packaging and crating, fragility. Denser, tightly packed loads rate a lower class and cost less to ship.
How do I find the exact freight class for furniture?
Measure your shipment and divide weight by volume to get density, then match it to the NMFC scale — the calculator above does this. Confirm the final class and NMFC item number with your carrier before booking.
What freight class is a sofa or couch?
Assembled upholstered sofas typically measure 3–5 lb/ft³ → class 200–250 boxed. Sections shipped separately, or frames shipped KD for local assembly, measure considerably denser. Measure the actual carton or crate at its extremes.
What freight class is flat-pack furniture?
Palletized knock-down furniture commonly measures 7–10 lb/ft³ → class 100–125. It's the single biggest class advantage in the furniture category — the same pieces assembled rate 200–300.
Should I crate or blanket-wrap assembled furniture?
Blanket-wrap on a skid measures closest to the piece's own dimensions and rates best; boxing adds clearance on every face; full crating adds the most protection and the most cube. Match the tier to the lane's handling risk — and price the difference with the calculator before deciding.
