Our sources
The full register: who said it, when we read it, and which sentence of ours leans on it.
Every outside source cited anywhere on this site, with the organisation behind it, the date we read it, and the exact claim of ours it supports. If a sentence on this site leans on authority, the authority is on this list; if it is not on this list, the sentence stands on the catalogue's own numbers or plain arithmetic.
| Source | Organisation | Read on | What it supports here |
|---|---|---|---|
| Dust Mite Allergy: How to Identify and Treat | Asthma and Allergy Foundation of America | 2026-08-01 | Three claims on the care and protection pages: wash bedding weekly in water of at least 130°F because that temperature kills dust mites, use zippered covers with pores too small for mites on pillows and mattresses, and replace pillows about every two years. |
| CertiPUR-US Certification Program | Alliance for Flexible Polyurethane Foam, Inc. | 2026-08-01 | What the foam certification covers (polyurethane foam tested for formaldehyde, phthalates, heavy metals and low VOC emissions) and that the programme keeps a public directory of participating companies, so the memory foam guide tells you to check the directory yourself rather than take any catalogue's word for it. |
| Changing Your Sleep Habits | MedlinePlus, National Library of Medicine (NIH) | 2026-08-01 | The framing of the cooling guide: a bedroom should be quiet, dark and at a temperature you find comfortable. Fabric can help with the last of those, and the guide claims no more than that. |
Reading a source is a dated act, and pages change after we read them. If a link above now says something different from what we cite, that is exactly the correction mail we most want to receive.
