What we typed
Herman Miller Aeron office chair, disassembled in original box
Naming the exact model is what tightens the numbers. Type only the word chair and the estimate leans on a category average; the Aeron's real carton is what you want priced.
An office chair disassembled — base, cylinder, and back separated — packs to about 28 × 26 × 24 inches at 35–55 lb. Shipped assembled it becomes an oversize parcel with a much worse quote, so disassembly is the cost lever. What you actually pay comes down to lane, speed, and the size of the finished carton, so price the real box rather than a guess.
This page's worked example: a 30 × 26 × 25 in carton at 45 lb, priced at $224.83 for UPS Ground on the Detroit to Las Vegas run below.
We fed “Herman Miller Aeron office chair, disassembled in original box” to the SMKlog calculator on 2026-07-24 and asked it to price Detroit, MI 48226 against Las Vegas, NV 89101. Every figure that follows came straight out of that session; we never weighed or measured anything ourselves.

Two genuine ZIP codes, priced live. The zone distance between them does more to this figure than any other input on the page.
The math worth noticing: 30 × 26 × 25 ÷ 139 comes to roughly 140.3 lb of dimensional weight, which beats the 45 lb the chair actually weighs. Every rate in this table is therefore priced off the carton, and shaving the carton is the cheapest fix available.
| Carrier | Service | Price | Estimated transit |
|---|---|---|---|
| UPS | Ground | $224.83 | 5-6 business days |
| UPS | 3Day Select | $379.21 | 4-5 business days |
| UPS | 2nd Day Air | $522.82 | 3-4 business days |
| FedEx | Ground | $590.48 | 5-6 business days |
Each figure is the checkout total: carrier label and SMKlog's portion together, with nothing tacked on afterwards. UPS Ground took this particular run at $224.83. A quote pulled next month, or between a different pair of ZIPs, will land somewhere else entirely, so read the table as a reference point and price your own lane for a current figure.
Around 28 × 26 × 24 in once the chair is apart. Base and casters come off the cylinder, the back comes off if its mechanism permits, each piece gets wrapped, and the dense parts ride low in the carton with the bolt bag taped to the seat mechanism.
Expect 35–55 lb broken down. Rates key off the larger of scale weight and box-math weight, which means a roomy carton quietly inflates the bill even when the contents are light. Seal it, then measure it.
Lane, speed, and carton. Detroit to Las Vegas crosses a lot of zones, which is most of why one box spans $224.83 to $590.48 in the table above; a short regional hop would sit far lower and an air upgrade far higher. A single flat number would be fiction, so the calculator quotes the route you actually have.
Budget roughly 28 × 26 × 24 in for the packed carton. Separate the base and casters from the cylinder, take the back off where the mechanism allows it, wrap every piece on its own, and load the heaviest parts at the bottom. Collect the bolts in one bag and tape that bag to the seat mechanism.
A broken-down chair usually lands between 35–55 lb. Whatever the scale reads, the carrier compares it with dimensional weight (length × width × height over the carrier divisor) and bills the larger figure, so measure the sealed carton before trusting any quote; a low guess simply gets corrected on the carrier's invoice after delivery.
Roughly half the carton volume disappears when the chair comes apart, dimensional weight falls with it, and the parcel can drop back out of oversize-surcharge territory. Those ten minutes with an Allen key pay better than anything else in the job; if you're torn, price both configurations and compare.
The approach is identical, the stakes higher: nothing hard may press into or puncture the mesh, so pad the frame edges and keep the bagged bolts well clear of it. Photograph the tilt mechanism settings before teardown and the buyer can restore the chair exactly.
Billed weight, mileage, and speed decide it. A 28x26x24 in carton holding 45 lb carries a dimensional weight of 126 lb (L x W x H / 139), and since carriers charge whichever figure is larger, you are rated at 126. Layer on the zone count and your ground-or-air choice and the number is set. The SMKlog calculator prices your actual lane and carton against live USPS, UPS, and FedEx rates without you touching a scale.
Ground with UPS or FedEx tends to win at this scale. USPS runs the same dimensional math on anything past one cubic foot, and a 126 lb billed figure plays to the big-box networks anyway. Any inch trimmed from the carton comes straight off the billed weight, and an online commercial-rate label usually lands 20-40% under what the same service costs at the counter.
