Most do, but the length varies. Newentor offers a 120-night risk-free trial with free returns, plus a 10-year warranty.

Yes. Newentor is designed for the Australian market, uses OEKO-TEX STANDARD 100 and CertiPUR-US certified foams, and is trusted by 500,000+ customers worldwide. Every mattress comes with a 120-night risk-free trial and a 10-year warranty.

The Newentor Hybrid Mattress Pro delivers premium 7-zone hybrid engineering at a fraction of the price of Emma, Ecosa or Koala, while still including a 120-night trial and 10-year warranty.

Look for a hybrid with zoned pocket springs. The Newentor Hybrid Mattress Pro uses 7-zone pocket springs that firm up under the lower back and hips to keep the spine aligned, which is why it's our top pick for back pain.

For most buyers the best value is the Newentor Hybrid Mattress Pro. It offers 7-zone dual-spring support, a medium-firm feel, a 120-night risk-free trial and a 10-year warranty, at a price well below premium rivals like Emma, Ecosa and Koala.

1. Identify Your Sleeping Position
Your primary sleeping position determines where you need support and where you need pressure relief.
Side Sleepers: You need a mattress with more "give" to cushion the shoulders and hips. Soft to Medium-Firm mattresses (often memory foam or plush hybrids) work best to keep the spine aligned.
Back Sleepers: You need a balance of support and comfort. A Medium-Firm mattress is usually ideal to prevent the lower back from sinking while still contouring to the spine’s natural curve.
Stomach Sleepers: You require a Firm mattress. If the bed is too soft, your hips will sink, arching your back and causing neck and shoulder pain.
Combination Sleepers: If you switch positions, look for a Medium-Firm Hybrid. The springs provide the "bounce" needed to move easily, while the foam layers adapt to different positions.

2. Understand the Materials
Memory Foam: Excellent for pressure relief and "hugging" the body. It absorbs motion well (great for couples), but can sometimes retain heat.
Innerspring/Pocket Spring: Offers a traditional bouncy feel and strong edge support. It is generally cooler due to the airflow between the coils.
Hybrid: Combines a spring base with foam or latex top layers. This is often considered the "best of both worlds," offering support, breathability, and comfort.
Latex: Known for being durable, eco-friendly, and naturally cooling. It feels more "responsive" than memory foam (you sit on it rather than in it).

3. Consider Key Performance Factors
Zoned Support: Look for mattresses with "3-zone," "5-zone," or "7-zone" support. These designs use different tensions to provide firmer support for the heavy parts of your body (hips/waist) and softer support for the lighter parts (head/legs).
Temperature Regulation: If you are a "hot sleeper," prioritize mattresses with cooling gel, breathable covers (like Tencel or Cotton), or hybrid designs that allow for airflow.
Edge Support: This is important if you sit on the edge of the bed or sleep near the side. Reinforced edges prevent that "sliding off" feeling.

4. Look for a Risk-Free Trial
The only way to truly know if a mattress works for you is to sleep on it.
Most "mattress-in-a-box" companies offer a 100-night to 120-night trial.
Ensure the brand offers a full refund and free returns if you decide it isn't the right fit.
Verify that the warranty is at least 10 years long, covering significant sagging or manufacturing defects.

Generally, yes. Hybrid models—particularly the Newentor Hybrid Pro or Origin—offer superior temperature regulation compared to traditional all-foam beds. This is because the internal spring systems (like Newentor's 7-zone pocket springs) create natural air corridors that allow heat to escape, whereas dense foam tends to trap body heat.

In the Australian climate, most mattresses from brands like Newentor or Koala expand to about 90% of their size within the first few hours. However, it typically takes 24 to 48 hours for the mattress to fully regain its structural integrity and for the comfort layers (especially hybrid spring systems) to settle into their intended firmness.
