What Does an Ultra Firm Mattress Feel Like?
An ultra firm mattress feels solid and supportive, with very little padding on top. You lie on the surface rather than in it, and your hips and shoulders stay level. On a 1 to 10 firmness scale, ultra firm sits around 9 to 10.
| Feel | Firmness (1 to 10) | Who It Suits |
|---|---|---|
| Firm | 7 to 8 | Back and stomach sleepers |
| Ultra Firm | 9 to 10 | Maximum support preference |
| Medium Firm | 5 to 6 | Most sleepers |
Who Should Choose an Ultra Firm Mattress?
- Stomach sleepers: It keeps the hips from sinking and the lower back neutral.
- Back sleepers who like a hard surface: It gives a flat, stable base.
- Heavier sleepers: A strong core resists dipping and keeps support over time.
- People who prefer a firm floor-like feel: Some sleepers simply feel best on a very firm bed.
Side sleepers usually find ultra firm too hard at the shoulders and hips. A medium firm or plush mattress is likely to be more comfortable.
Ultra Firm Mattresses by Size
Our ultra firm mattresses are available in sizes from single and king single to double, queen, king and super king. Firm sleepers sharing a bed often choose a queen or king for extra room. Check each product page for the sizes currently in stock.
