Independent testing
How much independent testing exists for each mattress
Of the 10 mattresses we track, 8 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| Saatva Classic | 2 | 7 | 2 |
| Helix Midnight | 2 | 4 | 2 |
| Brooklyn Bedding Signature Hybrid | 2 | 2 | 2 |
| Leesa Original | 2 | 2 | 2 |
| Avocado Green Mattress | 2 | 1 | 2 |
| DreamCloud Classic Hybrid | 1 | 7 | 1 |
| Nectar Premier | 1 | 3 | 1 |
| TEMPUR-Adapt | 1 | 1 | 1 |
| Purple Mattress (Original) | 0 | 0 | 2 |
| Tuft & Needle Original | 0 | 0 | 3 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Mattresses buying guide and the reviewers we cite.
