Less guesswork.
More room to rest.

Mattress Index is an independent comparison and purchase-planning project. We organize dated mattress specifications, compare published manufacturer policies and build simple tools to make practical trade-offs easier to understand.

What we contribute

The workbench lets you compare three models without a universal winner. The room-fit calculator visualizes the space around a bed. The cost calculator makes your usage assumptions visible. The buying checklist separates trial length from return fees and conditions. Our policy research records primary-source links and flags disagreements between official pages.

What we have actually checked

The model catalog is an April 19, 2026 historical snapshot. The five-brand trial-policy comparison was separately checked October 28, 2026. We have not laboratory-tested or slept on these models, and we do not present medical advice or verify marketing claims through independent testing.

How the project is funded

Display advertising supports the site. Current brand links lead to manufacturer websites. Advertisers do not buy comparison order or editorial conclusions. Any future tracked affiliate links will carry a clear disclosure.
