Frequently Asked Questions

How do I know if a mattress is right for me?▾
The best indicator is how you feel after sleeping on it for 3–4 weeks. Most reputable Australian brands offer 100–120 night trials specifically so you can assess this at home. Your body typically takes 2–3 weeks to adjust to a new mattress.
What mattress trial period should I look for?▾
Look for at least 100 nights — this gives your body enough time to adjust and you enough time to assess the mattress across different conditions. All of our recommended Australian brands offer 100 nights minimum.
Are mattress-in-a-box brands good quality?▾
Yes — brands like Koala, Emma, and Ecosa offer genuine quality comparable to traditional retail mattresses at better prices, because they sell direct without retail markup. The free trial period means you can test at home with no risk.
