What this product is
Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.
The most transparent entry in this ranking, and the one to buy if durability is your priority.
Ravensberger publishes its complete Stiftung Warentest sub-score table, which almost no manufacturer does. From the Matratzen 03/2025 programme, tested as 90×200 H4:
| Criterion | Grade | Weight |
|---|---|---|
| Liegeeigenschaften | 2.2 | 35% |
| Liegekomfort | 2.2 | 10% |
| Haltbarkeit | 2.0 | 25% |
| Bezug | 1.4 | 10% |
| Gesundheit und Umwelt | 1.6 | 10% |
| Handhabung | 3.0 | 5% |
| Deklaration | 3.0 | 5% |
Overall 2.2 "gut", one of the test winners among 14 mattresses up to €630, with the note that it achieved good lying properties for all tested body types in the back-sleeping position. Not both positions — that was the f.a.n. — but all body types in one.
The foam density is the headline specification: RG 50 kg/m³. That is the highest of any foam mattress here and comfortably above the recommended 40 kg/m³ minimum aligned with DIN 13014. Indicative service life at 50–60 kg/m³ is around ten years, against five to six at 35.
It has seven zones, about 18 cm total height with a 16 cm core, and comes in H2 (up to ~80 kg), H3 (from ~80 kg) and H4 (from ~110 kg) — the widest firmness range here, though remember these grades are not standardised. The RAVOTEX cover is 50% cotton and 50% polyester, washable at up to 60 °C.
Two soft spots visible in the sub-scores. Handhabung and Deklaration both scored 3.0 — handling and how well the product is declared. The first probably reflects weight and the difficulty of turning it; the second is a labelling matter rather than a performance one.
The trial period is 30 nights — the shortest here — with a 10-year guarantee.

FAQ
Frequently asked questions
How much difference does RG 50 make?
It is the difference between a mattress that lasts and one that softens. Indicative service life by density runs roughly: 30 kg/m³ two to three years, 35 kg/m³ five to six, 40 kg/m³ six to eight, 50-60 kg/m³ about ten. The recommended minimum is 40, aligned with DIN 13014, the hospital-mattress standard. At RG 50 this is the most durable foam mattress here — and note that its Stiftung Warentest durability sub-score of 2.0 is good but not exceptional, which is a useful reminder that density is a proxy rather than the whole story.
Which firmness should I choose?
Ravensberger's guidance is H2 up to about 80 kg, H3 from 80 and H4 from 110 — but remember Stiftung Warentest states that manufacturers' firmness grades often do not match, and there is no European standard defining them. Its measured test was on the H4. Firmness also does not determine lying quality: Stiftung Warentest says plainly that a soft mattress can support the spine just as well as a hard one. Use the 30-night trial.
