Why Sutherland Shire locals choose the Sleep Firm range

If you live in Cronulla, Miranda, Sutherland, Caringbah, Gymea, Engadine, Menai or anywhere across the Sutherland Shire and you've been searching for a genuinely firm mattress, the Sleep Firm range is what you've come in for. It's Australian-made in Melbourne by Chiropedic, rated a consistent Firm 8/10 across all three models, and has just been named Australia's Best Firm Mattress for the third year running by BedBuyer (2024, 2025 & 2026).

Most "firm" mattresses sold by the big national chains use cheap convoluted foams that compress and sag within twelve months. The Sleep Firm range uses a high-density pocket-spring core, hand-quilted comfort layers, and only GECA-certified, Sensitive Choice approved, ASRF endorsed materials - the firm feel you buy is the firm feel you'll still have ten years from now. Every model carries a 15-year warranty.
