COM & COL Explained: Using Your Own Fabric or Leather

COM and COL let a designer keep full control of the textile while the manufacturer handles construction. Here’s how it works in practice.

What COM and COL mean

COM is Customer’s Own Material; COL is Customer’s Own Leather. You supply the fabric or hide from your preferred mill, and we build the piece with it. It’s the standard way designers keep exact control of the textile spec — pattern, colorway, performance rating — while the workshop handles frames, foam, and upholstery.

How the process works

  • Spec the material. Choose your fabric or leather; note the vendor, pattern, and width.
  • We confirm yardage. On your shop drawings, we calculate the yardage (or hides) each piece needs — including pattern repeat and railroading — before you order a single roll.
  • You route the goods. Ship the material to our Los Angeles factory at 16520 Avalon Blvd, Carson, CA 90746 — or have your vendor drop-ship it — referencing your project so we can match it to your order on arrival.
  • We build. Cut, sewn, and upholstered in-house on frames we build ourselves, so the whole piece is under one roof.

Planning your COM yardage

Use rules of thumb to budget, and shop drawings to buy. As typical contract planning figures on 54-inch plain goods: an upholstered chair seat pad takes roughly half a yard, a fully upholstered side chair 1.1–2 yards, a club chair 4–6 and more on a high or privacy back, a three-seat sofa 10.5–14, an ottoman 2–3, an upholstered headboard 5–13 depending on style rather than bed size, and a banquette 1–3 yards per linear foot depending on back height and whether the outside back is upholstered. Contract seating is built differently from residential — most yardage charts on the open web are residential slipcover charts and run several times high on a commercial chair. The full piece-by-piece chart is in the COM yardage chart.

Three things move those numbers: pattern repeat (large repeats can add 20% or more for matching), railroading (running fabric sideways changes cut efficiency, especially on long banquette runs), and leather, which is bought by the hide and estimated in usable square feet rather than yards. These are planning estimates for typical constructions — we confirm the exact yardage or hide count for every piece on your shop drawings before you place the mill order, so you neither over-buy nor come up short mid-production.

Why it matters for commercial projects

COM/COL keeps the textile budget and the performance spec (cleanability, TB 117-2013 compliance, wear rating) in your hands, with no showroom markup on the fabric. It also makes the piece reupholster-ready down the line. We accept COM and COL on every piece we build.

Frequently Asked Questions

What is the difference between COM and COL?

COM is Customer’s Own Material (fabric); COL is Customer’s Own Leather. In both, you supply the covering and the manufacturer builds with it.

How do I know how much fabric to order?

We confirm yardage on your shop drawings — accounting for pattern repeat and railroading — before you order, so you don’t over- or under-buy.

Do you accept COM/COL on every piece?

Yes. Customer’s Own Material and Customer’s Own Leather are welcome on any piece we build.

How much COM fabric do I need per piece?

As typical contract planning figures on 54-inch plain goods: about half a yard for an upholstered chair seat pad, 1.1–2 yards for a fully upholstered side chair, 4–6 for a club chair, 10.5–14 for a three-seat sofa, and 1–3 yards per linear foot of banquette depending on back height. Pattern repeat, fabric width, and leather all change the math, so we confirm the requirement on your shop drawings before you order.

Where do I ship my COM material?

Ship or have your mill drop-ship it directly to our Los Angeles factory at 16520 Avalon Blvd, Carson, CA 90746, referencing your project — and don’t order the fabric until we’ve confirmed yardage on your shop drawings.
