Furniture and glass are among the most expensive freight categories per pound. Both share three problems: low density, fragility, and awkward stowability. Class typically lands at 65–200+.
This guide covers common items and how to ship them at the correct freight class.
| Item | Typical Class | Notes |
|---|---|---|
| Wood chairs (KD, boxed) | Class 65–85 | KD = knockdown (flat-packed) = denser = lower class. |
| Wood chairs (assembled) | Class 100–150 | Assembled wastes trailer space. |
| Wood tables / desks (KD) | Class 70–110 | Pallet count and packaging matter. |
| Wood furniture, NOI (assembled) | Class 100–175 | Dressers, armoires, large case goods. |
| Metal furniture (filing cabinets, racks) | Class 60–85 | Dense metal — low class. |
| Office chairs (boxed) | Class 92.5–125 | Plastic + foam = low density. |
| Sofas, loveseats (couches) | Class 150–250 | Foam + fabric = very low density. Common rebill source. |
| Mattresses, boxed | Class 110–175 | King/queen sizes lower density than twin. |
| Mattresses, in mattress bags | Class 175–250 | Bag adds bulk without weight. |
| Bookcases, shelving (assembled) | Class 100–150 | Hollow construction. |
| Beds, headboards (KD) | Class 70–110 | Flat-packed. |
| Item | Typical Class | Notes |
|---|---|---|
| Glass, plate or sheet (crated) | Class 70–110 | Crating is mandatory — uncrated glass is refused or rebilled. |
| Mirror, framed | Class 92.5–150 | Frame + glass = fragile + low density. |
| Glassware, bottles, jars (packed) | Class 70–150 | Master cartons + dividers required. |
| Glass tabletops, mirrors (boxed) | Class 100–175 | Often A-frame crated for safety. |
| Ceramic tile, palletized | Class 55–70 | Dense — among the cheapest to ship. |
| Porcelain / pottery (boxed) | Class 65–110 | Packaging quality drives class. |
| Aquariums, fish tanks (empty) | Class 100–250 | Large volume, fragile. |
| Bathroom fixtures (toilets, sinks) | Class 70–110 | Heavy porcelain. |
A 200lb sofa in a 90×40×40 inch box has density ~3 PCF — Class 250 territory. Even when palletized, density rarely climbs above 8 PCF (Class 110). Furniture pricing is dominated by cubic feet, not weight.
Carriers know glass and mirrors break. Even at the same density, fragile items get one class higher than non-fragile.
Tall headboards, wide tabletops, irregular shapes — they prevent stacking. Trailer space waste = class up.
Same chair, KD (knockdown / flat-packed) is Class 65-85 but assembled jumps to Class 100-150. Ship KD whenever possible.
Many shippers default to "furniture, Class 100" — carriers will reweigh, remeasure, and rebill at Class 200+. Declare correctly upfront.
Loose or boxed glass plates (not crated) often get refused at pickup. If accepted, carrier will charge crating fee + rebill at higher class.
Bagged mattress (single layer plastic) = Class 175-250. Boxed = Class 110-150. Use a real box or compress-roll packaging.
Prepare:
ShipOnlines auto-calculates class from density and flags fragile items for higher-grade carriers.
