Mattress Topper Buying Guide
Choosing the right mattress topper can dramatically improve your sleep quality without the expense of replacing your entire mattress. Here’s what to consider when shopping for a mattress topper in Australia:
Material Matters
Different materials offer distinct benefits:
- Memory Foam: Excellent for pressure relief and motion isolation, but can retain heat (unless gel-infused or open-cell like Onebed’s Davina Foam)
- Latex: Naturally cooling, responsive, and durable, but typically more expensive
- Microfibre/Down Alternative: Budget-friendly, soft, and lightweight, but less supportive and durable
- Bamboo Blends: Natural antibacterial properties with good breathability, ideal for Australia’s climate
- Wool: Natural temperature regulation (warm in winter, cool in summer) but can be expensive
Thickness Considerations
The ideal thickness depends on your current mattress condition and sleep needs:
- 2-3cm: Minimal softness addition, best for slightly enhancing a newer mattress
- 5cm: The sweet spot for most toppers (like the Onebed Topper), offering substantial comfort without being too thick
- 7-8cm+: Maximum transformation (like the Emma Diamond Topper), best for significantly worn mattresses
Sleeping Position Compatibility
Your preferred sleep position should influence your topper choice:
- Side Sleepers: Need softer, pressure-relieving toppers (5-8cm) to cushion shoulders and hips
- Back Sleepers: Benefit from medium-firm toppers with good support (like Onebed’s 5-zoned design)
- Stomach Sleepers: Require firmer, thinner toppers to prevent spinal misalignment
- Combination Sleepers: Do best with responsive materials that allow easy movement
Temperature Regulation
For Australia’s climate, consider:
- Cooling Technologies: Graphite-infused foam (Emma Diamond), open-cell foam (Onebed), or gel-infused options
- Natural Materials: Bamboo blends (Bamboo Haus, Dreamaker) offer natural breathability
- Airflow Design: Look for ventilation channels or breathable covers
- Antimicrobial Treatments: Prevent bacteria and mould growth (like Bianca’s Ultra-fresh treatment)
- Motion Isolation: Important for couples (Onebed’s “Do Not Disturb” effect)
- Secure Fit: Deep elastic skirts prevent shifting (most toppers on our list feature 45-50cm skirts)
- Washable Covers: Make maintenance easier (Emma Diamond offers this)
- Trial Periods: Risk-free testing periods (Onebed and Emma offer generous trials)
Budget Considerations
Mattress toppers range dramatically in price, but remember:
- Under $100: Basic comfort enhancement (Giselle Bedding offers exceptional value)
- $100-$200: Good quality with specific benefits (Dreamaker Bamboo topper offers excellent mid-range value)
- $200-$300: Premium materials and technologies (Onebed and Emma offer top-tier performance)
- $300+: Luxury materials or specialized therapeutic benefits
While budget options can provide immediate comfort, investing in higher-quality toppers typically means better durability and performance over time—often working out cheaper per year of use.
Selection Criteria
When compiling this list of Australia’s best mattress toppers for 2025, we applied a rigorous selection process to ensure we’re recommending only the most worthwhile products:
Value for Money
We carefully analyzed the price-to-performance ratio of each topper. While the Giselle Bedding topper offers exceptional budget value at just $39.05, premium options like the Onebed Topper ($210-$273) and Emma Diamond Topper ($300) justify their higher prices through advanced materials and technologies that significantly enhance sleep quality.
Customer Satisfaction
We prioritized products with strong, verified customer feedback. All toppers on our list maintain ratings above 4.4/5 stars.
Material Quality & Construction
We assessed material quality, construction techniques, and durability. Onebed’s specialized Davina Foam with 5-zoned support represents cutting-edge technology, while the 300 thread count Cotton Japara cover on the Bianca Relax Right demonstrates premium construction. We also valued thoughtful design elements like Dreamaker’s box-stitching that prevents filling migration.
Sleep Enhancement Features
We evaluated each topper’s ability to address common sleep issues:
- Pressure relief (Onebed’s 5-zoned support)
- Temperature regulation (Emma’s graphite-infused cooling technology)
- Allergy protection (Dreamaker’s bamboo antibacterial properties)
- Motion isolation (Onebed’s zero transfer technology)
Australian Climate Suitability
Living in Australia means dealing with hot summers and variable temperatures. We prioritized toppers with cooling properties and breathable materials suitable for our climate, such as Onebed’s breathable open-cell structure and the natural temperature regulation of bamboo-infused options like the Bamboo Haus and Dreamaker toppers.
Frequently Asked Questions
How long do mattress toppers typically last?
The lifespan of a mattress topper depends primarily on its material quality and construction. High-density foam toppers like the Onebed Topper typically last 3-5 years with proper care. Microfibre toppers generally last 2-3 years before compression affects their comfort. Premium options with quality materials and construction (like those with 5-year warranties) will naturally outlast budget alternatives. To maximize lifespan, rotate your topper every 3-6 months and use a mattress protector.
Can a mattress topper fix a sagging mattress?
A mattress topper can improve comfort on a slightly sagging mattress but won’t fix structural issues. For minor dips (1-2cm), a thick, firm topper like the 8cm Emma Diamond or 5cm Onebed can help bridge the gap and provide more even support. However, for significant sagging (3cm+), you’re better off replacing the mattress entirely. Think of toppers as comfort enhancers rather than structural repairs.
Are foam mattress toppers hot to sleep on in Australian summers?
Traditional memory foam can retain heat, but modern foam toppers use advanced cooling technologies. The Onebed Topper features highly breathable open-cell Davina Foam that allows airflow, while the Emma Diamond Topper uses graphite-infused foam specifically designed to draw heat away from your body. For maximum cooling in Australian summers, consider bamboo-blend toppers like the Bamboo Haus or Dreamaker, which offer natural temperature regulation.
How do I clean a mattress topper?
Cleaning methods vary by material:
- Foam toppers (Onebed, Emma): Spot clean with mild detergent and water; some have removable, machine-washable covers
- Fibre toppers (Giselle, Dreamaker): Many are machine washable on gentle cycles; follow manufacturer instructions
- Premium toppers (Bianca): May require professional cleaning or gentle hand washing
Always check the care label, as improper cleaning can void warranties. For all toppers, using a washable mattress protector will significantly reduce cleaning needs.
Apart from keeping your mattress topper clean, it’s important to maintain your mattress as well. Check out our guide on how to clean a mattress for practical tips to keep your entire sleep system fresh and in optimal condition.
How thick should a mattress topper be?
The ideal thickness depends on your needs:
- 2-3cm: Minimal softness addition
- 5cm: Standard thickness (like Onebed and Bianca) for significant comfort improvement
- 7-8cm: Maximum transformation (like Emma Diamond) for very firm or worn mattresses
Side sleepers typically benefit from thicker toppers (5-8cm) to cushion shoulders and hips, while stomach sleepers should choose thinner options (2-5cm) to prevent spinal misalignment.
Conclusion
The beauty of mattress toppers is their ability to dramatically improve your sleep quality without the expense of a new mattress. Whether you’re dealing with a too-firm mattress, seeking pressure relief, or simply wanting to extend the life of your current bed, the right topper can transform your sleep experience.
