When shopping for a mattress, firmness can be surprisingly subjective. What feels “medium-firm” in one bed may feel much softer or firmer in another, largely because different materials change how firmness is experienced. Beyond the number on the label, the construction of a mattress plays a major role in how it supports your body, relieves pressure, and responds to movement. Understanding these material differences can help you choose a mattress that truly matches your comfort needs.
Memory Foam
· Feels softer due to contouring
· Excellent pressure relief
· Firmness may feel lower than advertised
Memory foam mattresses are known for their deep contouring and body-hugging feel. Because the material compresses closely around pressure points like the shoulders and hips, memory foam often feels softer than its advertised firmness level. This contouring provides excellent pressure relief, making it a popular option for people with joint or muscle pain. However, sleepers who prefer a more lifted or responsive feel may perceive memory foam as too soft, especially over time.
Latex
· Naturally responsive and supportive
· Feels firmer and more buoyant
· Maintains shape well over time
Latex mattresses offer a very different experience. Naturally responsive and supportive, latex gently contours without allowing the body to sink too deeply. This creates a firmer, more buoyant feel compared to memory foam, even at similar firmness ratings. Latex also maintains its shape well over time, making it a durable option for sleepers who want consistent support and a slightly springy surface.
Hybrid
· Combines foam comfort with coil support
· Balanced feel across firmness levels
· Suitable for a wide range of sleepers
Hybrid mattresses combine foam comfort layers with a coil support system, delivering a balanced feel across firmness levels. The foam provides cushioning and pressure relief, while the coils add structure, airflow, and responsiveness. Because of this combination, hybrids tend to suit a wide range of sleepers, including couples and those who want both comfort and support without extreme softness or rigidity.
Innerspring
· Feels firmer and more responsive
· Less contouring
· Better airflow and ease of movement
Innerspring mattresses, on the other hand, feel the firmest and most responsive of the traditional options. With minimal contouring and a strong coil system, they make it easier to move and sleep cooler due to better airflow. When choosing firmness, it’s also important to consider factors like pressure relief for pain-prone areas, temperature regulation, motion isolation for couples, and edge support for maximising usable sleep space. Balancing material type with these needs will help you find a mattress that feels just right night after night.
Additional Factors to Consider When Choosing Firmness
Pressure Relief
If you experience shoulder, hip, or joint pain, prioritise firmness levels that allow some contouring.
Temperature Regulation
Softer mattresses often retain more heat, while firmer or hybrid models tend to sleep cooler.
Motion Isolation
Couples may prefer slightly softer mattresses with foam layers to minimise motion transfer.
Edge Support
Firmer mattresses and hybrids usually provide stronger edge support, increasing usable sleep space.
