How we research

What we do

We compare products on the measurements that decide whether they suit a person and a room: seat depth and height ranges, published user height and weight limits, desk surface sizes and height ranges, weight capacity, screen size, resolution, mounting and ports. For each product we read the manufacturer’s own specification pages, manuals and spec sheets, and the product’s Amazon listing.

Every fit number on the site carries the source it was read from, and each guide lists those sources at the end. When a manufacturer does not publish a number, the page says “Not published”. We never estimate it.

What we do not do

• We have not tested the products in our guides ourselves, and we do not claim long-term use. A guide will say so explicitly if that ever changes.
• We do not quote users or invent reviews, and we do not show star ratings.
• We do not accept payment for placement. Rankings are our own editorial judgment from the published data.

Prices and availability

Prices, availability and sellers come from Amazon’s Creators API and are refreshed regularly. Each guide shows the date prices were last checked. Prices change often, and the price on Amazon at checkout is the one that counts. On deal pages we only show a reference price when Amazon itself reports one; otherwise a price is the current price, not a sale price.

Brands that sell direct

Some of the best-known names in home office furniture, such as Herman Miller and Humanscale, mostly sell direct rather than on Amazon. We lead with what Amazon stocks, because that is where we can verify price and availability, but we mention direct-sale products where they are genuinely the better choice and say plainly that we earn nothing on them.

How we calculate monitor viewing distance

Manufacturers rarely publish a viewing distance, so we calculate one from the screen’s diagonal and resolution and label it as calculated. The near limit is the distance at which the screen’s width fills a 60° horizontal field of view, and never closer than 20 inches, the lower end of OSHA’s 20 to 40 inch guidance for computer work. The far limit is the distance at which the width fills 40°. We also note the distance beyond which individual pixels blend for typical vision (one arc-minute per pixel). See what size monitor fits your desk depth for how this maps to desk depth.

Units

We show US units first with metric in brackets, converted from whichever unit the manufacturer published. Conversions are rounded to the nearest half inch or whole centimeter.

Corrections

If a number on the site does not match the manufacturer, tell us through the contact page and we will check and correct it.
