About Felt & File

What this site is

Why these two subjects on one site

Because they are one problem with two halves, and anyone who has worked from a spare bedroom knows it.

A room stops working for two reasons. It sounds wrong - calls echo, you can hear the household and they can hear you, and the microphone makes you sound like you are in a bathroom. Or there is paper everywhere - on the desk, in piles, in boxes that were meant to be temporary two years ago.

Those are usually the same room and frequently the same week. The name is the strategy: felt is the acoustic material and file is the filing cabinet, which is the whole site in two words.

What this site deliberately does not cover: desks, task chairs, monitor arms, standing desks and walking pads. Those are covered better elsewhere and have nothing to do with either half of the problem above.

Who writes it

Scooter M. I am an enthusiast who is genuinely into this. I read the spec sheets and the installation manuals, compile the published figures, and do the arithmetic on the page so you can check it. No lab coat.

I have not handled these units and I say so every time. I own none of them, I have no sound meter, no treated room and no test rig. What I have is the patience to read 100 manufacturer specifications across six categories and the willingness to publish what is missing from them, which turned out to be more interesting than I expected.

I hold no credentials relevant to any of this - no acoustic engineering qualification, no trade certification, nothing. That is the honest answer rather than a gap, and where other sites in this niche display an implied credential, this one displays a method instead.

What we found by reading rather than testing

The approach produced findings a test would not have. Across roughly 100 products in six categories:

• Three acoustic panels out of eleven publish an NRC, and only one names the test standard behind it. The rest publish a percentage with nothing behind it.
• One file cabinet out of twenty-one publishes a drawer interior, which is the only way to know what a drawer holds without owning it.
• Not one office pod publishes a figure from ISO 23351-1, the standard written specifically for furniture-sized enclosures. They publish a building-element rating instead, and the difference matters.
• Not one acoustic partition publishes an absorption coefficient, so core material and thickness are the only evidence available in that whole category.
• Not one desk organizer publishes a load rating.

Those absences are the most useful thing on this site, and they came from documentation rather than from handling anything. The full method, including an explicit statement of what it cannot establish, is on how we pick.

What we publish, and what we will not

There are also no testimonials anywhere on this site, and there will not be until there are real ones with real attribution. This is a new brand and inventing a review would be the fastest way to be worth nothing.

How the site is funded

Amazon Associates. We earn a commission on qualifying purchases made through links here, at no extra cost to you. It never changes a ranking - several of our top picks are the cheapest products in their category, and the single best-value purchase on the whole site is a 17-dollar door sweep.

The full version is on affiliate disclosure, and the selection and correction policy is on editorial policy.

The publisher

Felt & File is published by Slate Mill Group. The brand is new - it launched in 2026 - and we would rather say that than invent a founding story. There is no company history here because there is not one yet.

Get in touch

Corrections are the most useful thing you can send. If a figure on this site does not match the manufacturer's own published specification, tell us which page and which figure and we will check it and fix it. Contact us.
