A swatch answers most questions a full sample would
If your question is about colour, fabric, board finish or a hardware brand, you need a material sample and not a whole piece of furniture. Swatches ship in an envelope, cost very little and arrive in days rather than weeks.
Ask for swatches early and ask for them from every supplier you’re seriously considering. Comparing five fabric samples on your own desk in your own light is worth more than an hour of comparing them under showroom lighting.
A full sample is for construction questions, and for contracts
When the question is how it is built, how it holds up or whether it fits, you need the actual piece. That’s expensive by air and slow by sea, so be sure the question is worth it.
For a contract or hotel order, a full sample isn’t optional. It’s the reference that settles arguments about batch three, and it needs to be signed, photographed and kept.
Expect to pay, and expect it credited
Most suppliers charge for a sample and many will credit it against a production order. Ask about the credit up front and get it noted on the invoice.
Be wary of pushing hard for free samples on a first contact. It marks you as a buyer who may not be real, which is the opposite of the impression you want.
Make the sample binding
A sample only protects you if production is contractually held to it. Sign it, photograph it from every angle including the underside, and have the supplier keep a matching sealed sample.
Then write on the order that goods must match the sealed sample. Without that line, an approved sample is a nice piece of furniture in your office and nothing more.
Watch for the golden sample problem
A sample built by hand by the best person in the workshop isn’t the same thing as the fiftieth unit off a production run. This is a well known gap and it isn’t always deliberate.
The way to manage it’s to ask that the sample come from normal production where possible, and to inspect early production rather than only at the end.
