What we typed
Upholstered dining chair, flat-packed
Saying “flat-packed” mattered here. A single word like “chair” gets a category-average guess; describing the actual shipment gets a box that matches it.
A single dining chair packs to about 26 × 22 × 38 inches at 16–35 lb. Its awkward shape makes dimensional weight matter as much as actual weight; upholstered and solid-wood chairs sit at the heavier end. Lane, service speed, and the box you end up taping decide the price, so feed the quote real measurements.
The numbers here come from a live rate: 37 × 22 × 6 in at 26 lb, UPS Ground $52.60 on the route below.
One entry, “Upholstered dining chair, flat-packed”, went into the SMKlog calculator on 2026-07-24 with a lane of Berkeley Heights, NJ 07922 to Los Angeles, CA 90001. The output is reproduced below untouched; no one weighed or measured a thing.

A genuine coast-to-coast lane, rated live. Zone distance is the single biggest lever on this price.
Flat-packing keeps this close, but the box still wins: 37 × 22 × 6 ÷ 139 is about 35.1 lb dimensional versus 26 lb actual, and the higher figure is the one the rates below charge for. Every trimmed inch is money back.

The amount at checkout already contains the label and SMKlog's charge; nothing else follows. UPS Ground came in lowest on this run at $52.60. Since carriers reprice all the time and no lane copies another, use this as a worked example only and put your own ZIP codes in for a current quote.
Assembled, expect roughly 26 × 22 × 38 in of box. Legs and backrest top get wrapped first since they catch and snap; if the legs unbolt, take them off and the carton shrinks a lot. Keep paper between cardboard and upholstery.
16–35 lb in the box. Actual weight or dimensional, whichever runs higher, is the billed figure, so measure what you actually taped; a chair-sized carton bills big even though the chair is not heavy.
Distance, deadline, dimensions. Berkeley Heights, NJ to Los Angeles, CA is about as long as a domestic lane gets; the same flat-pack to a nearby state would rate well under this, while anything expedited rates over it. Even within this one run the four services ranged $52.60 to $86.58. That spread is the argument for quoting your own route instead of trusting a flat figure.
Plan around 26 × 22 × 38 in packed. The legs and the top of the backrest are the parts that catch and snap, so wrap those first, and unbolt the legs if they come off to bring the box down. Put paper against any upholstery so the cardboard can't mark it.
Typically 16–35 lb packed. The rate is set by actual weight or dimensional weight (length × width × height divided by the carrier divisor), whichever is greater, so quote from the sealed box's real numbers. Guess low and the carrier corrects you after delivery, with a fee.
If they bolt on, yes. Legs off means a smaller box, less dimensional weight, and the most break-prone parts safely padded flat. Bag and label the hardware and pack it with the seat.
Paper and foam over wood keeps edges from scuffing; on fabric or leather, put paper down before any bubble wrap so nothing prints into the surface. The backrest top and leg tips take the hits, so pad them hardest.
Box size, almost entirely. A chair carton around 26x22x38 inches weighs about 25 lb, yet it computes to a striking 156 lb dimensional at UPS or FedEx, and the greater of the two figures is what gets billed. That gap, not the chair itself, is why quotes look high; zone and speed then multiply it. The SMKlog calculator prices your route and packed size with live USPS, UPS, and FedEx rates, and you never need a scale.
Get the box smaller before you compare carriers at all. Taking the legs off (covered above) can cut the 38-inch dimension dramatically, and each inch trimmed lowers the 156 lb dimensional weight you'd otherwise be billed for. At this size the realistic options are UPS and FedEx ground; their networks are the ones built for large boxes. An online label at commercial rates typically costs 20-40% less than the counter for the same service.
Not fully assembled, usually. USPS caps parcels at 130 inches of length plus girth, and a 26x22x38 chair box measures 134, past the limit. UPS and FedEx will take it, though a box this size sits in their large-package surcharge territory, which your quote already reflects. Shrink the box enough by removing the legs and USPS comes back into play.
