Your Office Is a Performance Tool

What is Commercial Office Interiors (COI)?
Commercial Office Interiors, or COI, is an open-line commercial office furniture dealer based in Hooksett, New Hampshire, an hour north of Boston. COI plans, specifies, delivers and installs office furniture for companies across New Hampshire and Greater Boston, then supports the furniture after move-in through the RESEAT lifecycle program. COI is not tied to one manufacturer: the same brief is priced across 100+ brands.
What does "100+ brands bid side by side" mean?
A major-line dealer is contracted to one manufacturer and prices your project from that catalog. COI is open-line, so the same specification goes out to several manufacturers at once and the bids come back on one line-itemed proposal. Across five New England projects in 2026 the gap between a single-brand bid and the COI open-line bid on the same scope averaged 32 percent. You see the alternatives, the lead times and the prices next to each other and choose.
How much does an office fit-out cost in New England?
Budget per seat, then multiply by headcount. Functional runs $2,500 to $4,500 per seat, professional $4,500 to $8,000, premium $8,000 to $15,000 and up. That is furniture only, installed, and excludes construction, AV and IT cabling. Roughly 55 to 65 percent of the per-seat number is the individual workstation, chair and storage. The rest is the conference rooms, reception, lounge and break areas everyone shares.
How long does office furniture take to arrive?
It depends on the manufacturer and the configuration. Across 124 New England shipments COI tracked in 2025, actual lead times ran 1.4 to 1.8 times the quoted figure. Artopex ships standard configurations in 4 to 6 weeks. Systems furniture from the large brands is often quoted at 8 to 14 weeks and lands at 12 to 18. COI builds the schedule around the slowest line item and specifies a quick-ship backup on task seating.
How fast can COI turn around a space plan?
Under 3 business days from the point COI has a floor plan and a headcount. You get a 2D layout and a 3D rendering of every room. There is no charge and no obligation to buy.
Where does COI work?
The core market is Southern and Central New Hampshire and Greater Boston, including Cambridge, the Route 128 corridor, MetroWest and the Merrimack Valley, plus Worcester, Providence and Southern Maine. Qualified multi-location projects elsewhere in the continental U.S. are reviewed case by case.
