Pressure Relief Mattresses vs Traditional Mattresses: What Research Actually Shows
Key Takeaways:
- Pressure relief mattresses use advanced foam layers and zoned support systems to distribute body weight evenly, reducing stress on joints and spine
- Traditional innerspring mattresses create pressure points at shoulders, hips, and lower back due to limited contouring ability
- Studies indicate pressure-relieving sleep surfaces may reduce tossing and turning by up to 80% compared to conventional mattresses
- Hybrid designs combining pocket springs with memory foam offer the benefits of both technologies
- People with chronic pain, arthritis, or circulation issues often experience measurable improvements with pressure relief technology
- The technology is no longer exclusive to medical-grade beds and has become accessible to everyday consumers
The mattress industry has undergone significant changes over the past decade, with pressure relief technology moving from hospital beds into homes across Australia. Yet many sleepers remain unclear about what differentiates these advanced sleep surfaces from the traditional mattresses they’ve used for years.
Understanding these differences goes beyond marketing claims. The distinction lies in fundamental engineering approaches to supporting the human body during sleep, with measurable effects on sleep quality, pain management, and overall wellbeing.
Understanding Traditional Mattress Construction
Traditional mattresses typically rely on continuous coil or Bonnell spring systems developed over a century ago. These designs feature interconnected metal springs covered by thin comfort layers, usually cotton or polyester batting. The springs compress uniformly under weight, providing general support without adapting to individual body contours.
This construction creates predictable pressure points. The shoulders and hips, which protrude furthest when lying on one’s side, bear disproportionate weight. Meanwhile, the natural curve of the lower back receives insufficient support, creating a gap between the spine and the mattress surface.
The lack of targeted support in traditional designs means the body must work to maintain alignment throughout the night. Muscles remain partially engaged rather than fully relaxing, contributing to the sensation of waking unrested despite adequate sleep hours.
How Pressure Relief Technology Works
Pressure relief mattresses employ multiple strategies to distribute body weight more evenly. The primary mechanism involves using materials that conform to body shape while maintaining supportive resistance.
Memory foam, developed by NASA in the 1970s for spacecraft cushioning, represents one approach. The material softens in response to body heat, allowing it to mold around contours. However, first-generation memory foam often trapped heat and felt overly soft for stomach or back sleepers.
Modern pressure relief systems address these limitations through layered construction. A typical design might feature cooling gel-infused memory foam for contouring, transition foam for support, and a base layer for stability. Some manufacturers incorporate zoned support, using firmer materials under heavier body sections and softer materials where less support is needed.
Advanced designs also integrate pocket springs, where each coil operates independently within its own fabric sleeve. This allows the mattress to respond precisely to pressure distribution across the entire sleep surface. When combined with pressure-relieving foam layers, these hybrid systems deliver both the contouring benefits of foam and the supportive responsiveness of springs.
The Science Behind Pressure Distribution
Research conducted by sleep science laboratories has quantified the differences between these technologies. Studies measuring interface pressure (the force between body and mattress) show traditional spring mattresses create pressure readings of 50-70 mmHg at the shoulders and hips. Pressure relief surfaces typically reduce these readings to 20-35 mmHg.
This matters because sustained pressure above 32 mmHg can restrict capillary blood flow. Reduced circulation triggers the body’s instinct to shift position, causing the micro-movements and position changes that fragment sleep cycles.
The Australian Sleep Health Foundation notes that adults change position approximately 40-60 times per night. Higher-quality sleep surfaces that minimize pressure points can reduce unnecessary movement, allowing deeper, more restorative sleep stages to persist longer.
Health Implications Beyond Comfort
The impact of sleep surface technology extends beyond subjective comfort into measurable health outcomes. Physiotherapists frequently recommend pressure-relieving mattresses for patients with chronic pain conditions, particularly those affecting the spine, hips, or shoulders.
Arthritis sufferers often find traditional mattresses exacerbate morning stiffness. The pressure concentration at affected joints can intensify inflammation and discomfort. Pressure relief technology distributes force across a larger surface area, potentially reducing strain on sensitive joints.
Circulation-related conditions also respond to improved pressure distribution. Pregnant women, who experience increased pressure on blood vessels, often report better sleep quality on pressure-relieving surfaces. Similarly, individuals with conditions affecting peripheral circulation may benefit from reduced pressure points.
Back pain, particularly lower back discomfort, represents another area where sleep surface technology makes a measurable difference. Traditional mattresses often allow the spine to curve unnaturally, with the lower back unsupported and the hips sinking too deeply. Proper pressure relief maintains spinal alignment through targeted support zones.
Material Technology Advancements
The evolution of foam technology has been substantial. Early memory foam suffered from heat retention and chemical odours. Contemporary materials incorporate open-cell structures that enhance airflow, gel infusions that draw heat away from the body, and plant-based components that reduce off-gassing.
Onebed utilises proprietary materials like Auralux foam, which combines memory foam’s pressure relief with latex-like breathability. These hybrid materials aim to eliminate the traditional trade-off between contouring comfort and temperature regulation.
The Australian company Onebed has also developed grid technology that creates air channels throughout the comfort layer, increasing breathability while maintaining pressure relief properties. This engineering approach addresses one of the primary complaints about pressure-relieving mattresses: the tendency to sleep hot.
Cost Considerations and Accessibility
Traditional mattresses have historically held a significant price advantage. Basic innerspring models remain available at budget-friendly price points, making them accessible to cost-conscious consumers. However, the mattress-in-a-box revolution has democratized access to pressure relief technology.
Direct-to-consumer brands have eliminated retail markup, reducing prices substantially. Models from companies like Onebed now compete directly with mid-range traditional mattresses while offering superior pressure relief technology. The queen-size Onebed Max, featuring five-zoned pocket springs and multiple foam layers, retails for considerably less than equivalent hybrid models from traditional manufacturers.
Extended trial periods have also reduced purchase risk. Many pressure relief mattress companies offer 100-120 night trials, allowing consumers to test the technology at home. Onebed provides a 125-night trial period, giving users ample time to adapt to the different feel of pressure-relieving materials.
Who Benefits Most From Pressure Relief Technology
While anyone can appreciate improved comfort, certain groups experience particularly significant benefits from pressure-relieving sleep surfaces.
Side sleepers constitute the largest beneficiary group. This position naturally creates the most pronounced pressure points, with shoulders and hips bearing concentrated weight. Traditional mattresses struggle to support side sleepers adequately, often forcing a choice between uncomfortable firmness or inadequate support.
People over 40 typically experience more joint sensitivity and reduced circulation, making pressure concentration more problematic. The body’s natural cushioning decreases with age, placing greater demands on the mattress to provide appropriate pressure distribution.
Couples with different body weights face challenges on traditional mattresses. Heavier partners often sink deeper, creating an uncomfortable slope. Pressure relief mattresses with zoned support and responsive materials can accommodate varying body types more effectively while minimizing motion transfer between sleep partners.
Athletes and physically active individuals require quality recovery sleep. Reducing pressure points allows muscles to relax more completely, potentially enhancing recovery processes. Several professional sports teams have invested in pressure-relieving mattresses for their facilities.
The Motion Transfer Factor
An often-overlooked advantage of pressure relief technology involves motion isolation. Traditional innerspring mattresses transfer movement across the entire sleep surface due to their interconnected spring systems. When one person moves or gets up, their partner feels the disturbance.
Pressure relief mattresses, particularly those using memory foam or pocket springs, absorb motion locally. Each movement affects only the immediate area, leaving the rest of the mattress undisturbed. For couples with different sleep schedules or restless sleepers, this feature can significantly improve sleep quality.
The Onebed Original and Max models utilize individually pocketed springs combined with foam layers specifically designed to minimize motion transfer. This engineering approach allows each sleeper to move independently without disturbing their partner.
Durability and Longevity Considerations
Traditional innerspring mattresses typically show wear after 5-7 years. The springs gradually lose tension, comfort layers compress, and sagging develops in high-pressure areas. Once sagging exceeds 3-4 centimetres, the mattress no longer provides adequate support.
Quality pressure relief mattresses often outlast traditional designs due to superior materials and construction. High-density foams resist compression better than conventional padding. Pocket spring systems, when properly manufactured, maintain tension longer than continuous coil designs.
However, durability varies significantly by manufacturer and price point. Low-quality memory foam can develop body impressions within months, while premium materials maintain their properties for a decade or longer. Warranties provide important protection, with reputable manufacturers offering 10-year coverage against defects and excessive sagging.
Environmental and Health Safety Concerns
Traditional mattresses often contain flame retardants, formaldehyde, and volatile organic compounds that off-gas into the bedroom environment. While regulatory standards have improved, concerns remain about long-term exposure to these chemicals.
Many pressure relief mattress manufacturers have adopted third-party certifications like CertiPUR-US and OEKO-TEX, which verify low chemical emissions and ban specific harmful substances. These certifications provide assurance that foams meet strict environmental and health standards.
Australian companies producing pressure relief mattresses must comply with stringent safety regulations. Products sold domestically undergo testing for chemical emissions and fire safety, providing consumers with additional protection.
Making an Informed Decision
Choosing between pressure relief and traditional mattress technology depends on individual needs, preferences, and circumstances. Traditional innerspring mattresses suit some sleepers perfectly, particularly those who prefer a firmer, more responsive feel or have a limited budget.
However, for individuals experiencing sleep disruption, chronic pain, or dissatisfaction with their current mattress, pressure relief technology offers measurable benefits. The key lies in understanding your specific needs and matching them to appropriate mattress characteristics.
Testing mattresses in person provides limited value since body adaptation to new sleep surfaces typically requires several weeks. This makes generous trial periods essential. The 125-night trial offered by Onebed and similar companies removes the guesswork from the purchase decision, allowing real-world testing in your own bedroom.
Consider your sleeping position, any existing pain or discomfort, partner motion concerns, and temperature preferences. These factors should guide your decision more than price alone, given the profound impact sleep quality has on daily functioning and long-term health.
The mattress industry continues evolving, with hybrid designs blurring traditional categories. Modern pressure relief mattresses address most historical drawbacks while delivering genuine improvements in sleep quality for many users. As technology advances and prices decrease, these sophisticated sleep surfaces have become a practical option for everyday Australians seeking better rest.
