    Sleep Firm - Mattress in a Box

    Introducing the Sleep Firm Mattress with Exclusive S+ Pro 5 Zone Independent Spring System designed for sleepers looking for straight out firm support without feeling like they are sleeping on the floor.

    This Australian Made Mattress in a box is an Australian first and is designed specifically for those sleepers who prefer a firm support and comfort layer.

    The Sleep Firm has been designed and manufactured by the award-winning team at Chiropedic. With extensive knowledge within the mattress industry spanning over 100 years, you will sleep well, knowing you are sleeping on superior experience and quality.

    The core of this mattress is the exclusive S+ Pro 5 Zone Independent Spring System. Designed for advanced strength and spinal alignment, each Independent Spring is specifically placed within each of the 5 Zones to ensure it responds and supports the natural contour of the spine and body. For added strength, durability and longevity each spring is individually wrapped in N-100 Medical Grade Fabric which is 42% Stronger than any regular pocket spring.
    To achieve its advanced strength, the S+ Pro Spring has a super high spring count spread out across the 5 Zones. This ensures maximum support for the body and spine by breaking the spring into multiple levels. Firm Support is provided for the head, lower back/hips and the feet. Slight pressure relief is then provided for the shoulders and knees for comfort.

    Above the S+ Pro spring is the Sleep Firms exclusive Boomerang Foam which has been specifically designed and engineered for a compressed mattress. This premium density foam has an extremely high rebound level that does not lose its hardness, ensuring long-lasting firm support. The Boomerang Foam by Dunlop is Geca Certified and treated with Ultra-Fresh, which is anti-microbial. It is also a Dunlop Approved foam with the National Asthma Council Sensitive Choice.

    The top layer of the Sleep Firm Mattress is made using a high grade Adaptive knitted fabric combined with quilted foam which works to eliminate body impressions within the quilting. Made with a Variable Pressure Foaming process, its open cell structure provides excellent moisture dissipation through the top quilted layer of the mattress. The Adaptive fabric by Bekaert Deslee responds dynamically to temperature changes and keeps your sleep environment cool and dry, all night, every night.

    To ensure a firm supportive edge to encase the S+ Pro Spring and to prevent any roll-off, we also use the Boomerang Foam to create a foam box edge around the full perimeter of the mattress. A foam box technique is something you would find in a traditional retail store pocket spring mattress.

    For the sides of the mattress, the Sleep Firm uses a 3D Spacer fabric which is designed to ensure maximum air circulation around the sides of the mattress.

    For peace of mind, the Sleep Firm Mattress comes with one of the best warranties on the market for a mattress in a box. We know this is a quality Australian made mattress manufactured using only the best materials, and as such, it comes with a 15-year Warranty.

    Chiropedic specifically excludes from the warranty;

    •  Minor manufacturing anomalies that do not impact the performance of the products ie. mis-stitching or loose stitching on quilting.

    •  Mattress fabric (including soiling, stains, burns, pilling, or loose covers).

    •  Normal Body indentations (less than 40mm).

    •  Issues relating to comfort choice, ie the mattress is too soft or too firm.

    •  Issues relating to temperature of products

    •  Issues relating to new product smell/odour

    •  Handles (where fitted) – these should be used only to position the mattress and should not be used to support the full weight of the mattress.

    •  The fit of manchester items.

    •  Mattress damage due to an inappropriate foundation.

    •  Damage due to incorrect storage of products.

    All mattresses should be rotated on a regular basis. Single sided mattresses need just to be rotated around 180 degrees. Two-sided mattresses need to be flipped over and rotated around 180 degrees. We recommend that a mattress should be rotated every 2 weeks in the first month after the purchase and then done once a month for the duration of the warranty period. Failure to rotate your mattress will void the warranty.

    During the warranty period, if Chiropedic is satisfied that material or workmanship is faulty, it will repair or replace the product at its option. However, the warranty period will not be extended or changed as a result of repair or replacement under the terms of this warranty or otherwise. Chiropedic will cover transport costs arising from repair or replacement under the terms of this Warranty during the first 12 months of the Warranty period. After 12 months transportation costs are to be met by the purchaser.

    Chiropedic reserves the right to substitute material of equal quality on the particular items being repaired or replaced if identical material is not available at the time of repair or replacement.

    Body Impressions, (small indentations) are normal on the surface of any new mattress whilst the upholstery filling is leveling to a final position and getting used to your body contours. This does not constitute a manufacturing fault. On a pillowtop mattress, up to 40mm height loss is considered normal. On a non pillowtop mattress, up to 30mm height loss is considered normal.


    Chiropedic mattresses are suitable for slat bases. There are important tips to know when considering a slat base to compliment your mattress.

    Correct mattress support is an important element in providing long life for the mattress. Mattresses always follow the contour of whatever they rest on. If placed on any base that dips down, even under the load of one or two sleepers, the guarantee may be voided. Bases dipping or sagging allow the mattress to sag, causing the top cover to wrinkle.

    Sleepers may experience roll together through inadequate support. Some slat/mesh type bases may require a centre rail and a leg to the floor to prevent dipping or sagging, particularly in Double, Queen and King sizes. Timber slats must be a smooth finish to prevent splinter and scuffing damage and be securely fastened to the frame at each end. A breathable insulating pad or blanket over the slats is advisable. Slats over 14cm wide may cause mildew by not allowing moisture to evaporate sufficiently. Solid panel timber bases must have sufficient air holes drilled to permit dispersal of moisture and prevent mildew. Bases must always be firm, even and supportive. Gaps between uncovered slats must not exceed 10cm, anything exceeding this does not ably support the spring system and can void the warranty.

    A base that is too hard, too soft, not supportive, or restricts air circulation may damage your mattress and void this guarantee.

    We recommend a specially designed Chiropedic Bedding base.  See Below.

    Please Note: Curved / Posture / Euro Slat Systems will void your warranty.

    The company reserves the right not to handle items for repair if, in its opinion, they have been tampered with or misused by the purchaser beyond reasonable wear or if the product has been physically damaged intentionally or due to accident and/or neglect: including burns, cuts, water damage, mould, stains, soiled by blood or urine and if it is unsanitary. Use of a waterproof mattress protector is a requirement at all times.

    Mattress and base specifications, including appearance, may change without notice.

    This warranty is in addition to, and not in substitution for, the right of the purchaser conferred by the trade practices act and/or the legislation of any State or Territory.
