How we compare

What we include

• Published facts only. Price, plan options, free-trial length, platforms, class formats, dimensions, thickness, materials, rated capacity and warranty, as stated by the brand.
• Every fact has a source. Each card links to the official page we used and the date we checked it (currently Oct 15, 2026).
• Gaps stay gaps. If we can’t confirm a detail on an official page, we show “See site” rather than guess.

What we don’t do

• We don’t make health, fitness, weight, sleep or mood claims, and we don’t repeat brands’ marketing claims.
• We don’t publish star ratings, “best overall” awards or invented reviews. We haven’t hands-on tested these products, so we don’t say we have.
• Commissions don’t change what we list or the order we list it in. Items appear in a fixed editorial order, and brands without affiliate programs (for example, Calm) are included too.

Keeping it current

Prices and plans change often. We recheck listings regularly and update the “checked” date. If you spot something out of date, tell us and we’ll correct it.
