All mattresses sold at yinahla.com.au come with a 100 Night Trial period.  

If you are not happy with the mattress for any reason within the mattresses qualifying trial period, you can swap it over for another mattress in our range or return it and get a full refund. However, we do suggest to our customers, to sleep on the new mattress for a minimum of 14 nights before deciding on an exchange. This ensures the body has had some time to adjust to the new mattress.

All returned mattresses are donated to our charity partner the Salvos to help those in need. Return shipping is free in all Metro location (Melbourne, Sydney, Canberra, Brisbane, Gold Coast, Adelaide, Hobart & Perth). If you are outside these metro locations, we will try to locate a charity in your area who can pick up your mattress. If we are unable to locate a charity that services your area, then you will need to arrange at your cost, to get the mattress to them or to a nominated depot in your closest metro location. 

As all 100 Night Trial returned mattresses go to charity, to live another life, they must be in an as-new condition with no damage, stains, marks or rips. All the customers should retain the original packaging of the mattress at least for 100 nights to use it during the return process.  We highly recommend using a mattress protector with your mattress. 

If you choose to swap over the mattress, then you will need to pay the difference in price if it is more expensive alternatively we will refund you the difference in price if it is cheaper.

Please note the trial is limited to one mattress swap or return per household, delivery address or order. If you need to purchase multiple mattresses, we recommend buying one first to make sure you are happy then placing another order.  

If you would like to swap or return your mattress, please email [email protected] 

Our entire Yinahla Mattress range is backed up by 20 Years Warranty. 

We offers a warranty against faulty workmanship and /or faulty materials commencing on the date the mattress and/or base was originally delivered to, or collected by the purchaser and is valid only to the original purchaser of the product as indicated on the original sales invoice. This warranty does not extend to normal wear and tear, or damage caused by abuse, misuse or negligence. Failure to comply with manufacturer's care and maintenance instructions will void your warranty.

Mattress Warranty Information

In addition to the other exclusions stated on this page, Chiropedic specifically excludes from the warranty;

• Small manufacturing irregularities that do not affect the performance of the bed.
• Comfort issues relating to the customers preferences.
• Fit of manchester items.
• Handles, as handles are not intended to be used to lift, turn or transport the product.

All mattresses should be rotated on a regular basis. Single sided mattresses need just to be rotated around 180 degrees. 2 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.

Base Warranty Information

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.

General Information

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 mattress protector is advisable 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.

• All Yinahla mattresses must be rotated on a regular basis. Single-sided mattresses need to be spun around 180 degrees (head to toe). Double-sided mattresses (where the sleep surface is identical on both the top and the bottom, ie. pillow top on the top on both sides of the mattress) need to be flipped over and spun around 180 degrees.
• All Yinahla mattresses must be rotated once per month for the duration of the warranty period. We recommend that you rotate your mattress twice in the first month after the purchase and then monthly thereafter as outlined above.
• All Yinahla mattresses MUST have a waterproof mattress protector on them at all times. This will help keep the mattress in a sanitary condition and prevent stains and moisture from bodily fluids reaching the mattress. Should moisture reach the mattress, it will likely result in the warranty being voided due to the unsanitary state of the mattress.
• All Yinahla mattresses MUST be placed on suitable supportive bases which are not too hard or too soft. Bases need to provide consistent support with un-covered gaps not exceeding 10cm and covered gaps not exceeding 14cm. They must also not restrict air circulation in any way. Failure to comply with this may damage your mattress and void your warranty. We recommend a specially designed Chiropedic Bedding base. For further information on a suitable base, please refer to our website.
