Why The Hills District chooses the Sleep Firm range

If you live in Castle Hill, Baulkham Hills, Kellyville, Bella Vista, Norwest, Rouse Hill, West Pennant Hills, Cherrybrook or anywhere across the Hills 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.

Compare all three side-by-side at our Prospect showroom

Our Prospect showroom at 27 Rowood Road - just off the M4, about 20 minutes from Castle Hill - has the full Sleep Firm range on display so you can lie down on the Standard, Luxe and Ultra back-to-back and feel the difference yourself. Our sleep specialists will help you choose the right model for your body type, sleeping position and budget.

What's the difference between the three Sleep Firm models? +

All three are rated Firm 8/10 and Australian-made in Melbourne by Chiropedic. The Sleep Firm (Standard) is the original pocket-spring core with a quilted cotton cover — from $824 and backed by a 150 Night Sleep Trial (refund or exchange). The Sleep Firm Luxe adds a gel-infused memory foam comfort layer and quilted pillow top — from $1,424 and backed by a 100 Night Comfort Guarantee (exchange only). The Sleep Firm Ultra is the tallest profile with extra-deep premium comfort layers, best for heavier sleepers and couples — from $1,124 and also backed by a 100 Night Comfort Guarantee (exchange only).

Is the Sleep Firm firm enough for back pain and stomach sleepers? +

Yes — all three Sleep Firm models are a true Firm 8/10. They're specifically designed for stomach sleepers, heavier back sleepers, and people with chronic lower-back pain who need to keep the spine in neutral alignment. The pocket-spring core resists sagging far better than the foam-based mattresses sold by most chains, and the firmness has been independently rated by BedBuyer as Australia's Best Firm Mattress for three years running (2024, 2025 & 2026).

What's the warranty and trial on the Sleep Firm range? +

Every Sleep Firm model carries a 15-year warranty. The Sleep Firm (Standard) is backed by Best in Beds' 150 Night Sleep Trial — if it's not right after 30+ nights, we'll refund or exchange. The Sleep Firm Luxe and Ultra are backed by the 100 Night Comfort Guarantee — exchange only, not refund — because they're premium-build models. All three are GECA-certified, Sensitive Choice approved and ASRF endorsed.

What sizes does the Sleep Firm come in? +

Sleep Firm is available in Single, King Single, Double, Queen and King. Queen is the most popular size (152 × 203 cm) and Double is great for guest rooms (138 × 188 cm). The Luxe and Ultra are taller-profile mattresses, so make sure your bed base has adequate clearance — pop into our Prospect showroom near Castle Hill, or call 02 8676 7321 before you order.
