Online mattress buyers in Australia report higher satisfaction than in-store buyers — because a 100-night home trial tells you more than a 2-minute showroom test ever could. Here’s exactly what to check before clicking “buy”.

Your Pre-Purchase Checklist

Before adding any mattress to cart, verify these five things:

1. Trial period: minimum 100 nights. This is non-negotiable for online purchasing. Brands offering shorter trials (or none) are a red flag. Koala offers 120 nights; Sleep Republic leads with 150 nights.
2. Free return pickup. Some brands advertise free trials but charge $100–$200 for return shipping. Confirm the return is genuinely free before purchasing.
3. Materials disclosure. The listing should specify foam type and density, spring count, and layer construction. “Premium materials” without specifics means the brand is hiding cheap construction.
4. Warranty: minimum 10 years. Read the fine print — most warranties cover structural defects and sagging over 3cm but exclude comfort preference changes.
5. Certifications: CertiPUR-US or OEKO-TEX for foam safety. Australian Made certification if local manufacturing matters to you.

How to Compare Without Lying On Them

Cross-reference firmness ratings between brands — one brand’s “medium” may be another’s “firm.” Your sleep position is a more reliable guide than subjective comfort terms: side sleepers need softer (4–6/10), back sleepers need medium-firm (6–7/10), stomach sleepers need firm (7–8/10).

Factor in your weight: if you’re over 85kg, add one firmness level to standard recommendations. Under 60kg, subtract one. This single adjustment prevents most online firmness mismatches.

Calculate Price Per Year, Not Sticker Price

A $2,000 mattress lasting 10 years costs $200/year. A $800 mattress lasting 4 years costs $200/year — same annual cost, different experience. Always divide by expected lifespan.
