View full detailsWhat is a firm mattress?
A firm mattress holds you in an elevated sleeping position with minimal sinking. The robust surface prevents sagging under pressure points like hips and shoulders, creating the foundation many sleepers need for proper spinal alignment and reducing morning stiffness.
While softer mattresses conform around your body, firm designs actively support your weight from below. Look for reinforced lumbar zones that prevent dipping where weight concentrates. High-gauge steel springs provide lasting tension without premature softening.
Edge support becomes crucial in firmer designs since the reduced cushioning can make borders feel unstable. Foam encapsulation or double-row spring systems ensure you can use the entire sleeping surface without that "rolling off" sensation.
Different types of firm mattresses
Traditional bonded springs and dense wool layers create reliable firmness at entry-level prices. These classic designs distribute weight evenly while minimising motion transfer.
Zoned pocket springs use varying coil tensions - firmer under hips, gentler at shoulders - to maintain alignment while preventing pressure buildup. The individual spring wrapping reduces partner disturbance without compromising on support.
High-density memory foam layers progressively increase in firmness, transitioning from a breathable surface to an ultra-supportive core. The graduated design prevents the "trapped" feeling some foam mattresses can create.
How a firm mattress feels
You'll notice immediate pushback that keeps your body level, with just enough give to accommodate natural curves comfortably.
The stable surface maintains consistent resistance under pressure points, making changing positions easily throughout the night.
Back and stomach sleepers often prefer this firmness level since it prevents hip sinking and supports the lower back. Heavier sleepers also benefit from the enhanced stability and reduced risk of dipping.
Outstanding firm options
The Farnborough 1000 provides substantial back support with pocket springs and a taped edge. The tufted padding keeps the sleeping surface level, and you can flip the mattress to prolong its life.
The Dura Beds Everlast 1000 combines individually tensioned pocket springs with reinforced edges, preventing the gradual softening that can occur along mattress borders. The hand-tufted surface locks premium fillings in place for lasting performance.
Memory foam technology meets orthopaedic support in the Sareer Diamond 6+2. The high-density base layer provides unwavering stability while the cooling gel-infused surface prevents heat buildup - a common concern with firmer foam designs.
The Deluxe Beds Avon Ortho 2000 features multi-zoned spring tensions that adapt to different body weights. Advanced air channels maintain freshness, while the two-sided construction doubles the mattress lifespan through regular rotation.
