Mattress Warranty

i-Mattress by King Koil are a perfect example of advanced mattress technology carefully engineered to give you the best night’s sleep. However, to give you further peace of mind, we are so confident that you will be satisfied with your mattress that we will replace any faulty mattress which falls within the scope of our 10 year guarantee as set out below.


1.1 This guarantee explains all options for resolution of a warranty claim.

1.2 This guarantee is effective from the date of delivery and expires 10 years from that date, save any invalidity which may arise by virtue of clause 4.

1.3 This guarantee relates to i-Mattress by King Koil only and not to any other goods sold by King Koil or its authorized retailers.

1.4 This guarantee is for your benefit, as the original purchaser, only and is not transferable to any other person. If you sell or otherwise relinquish ownership of the mattress, the subsequent owner accepts the product ‘as is’, including all faults, and will not be able to benefit from this guarantee.

Scope of guarantee

2. This guarantee may be invoked where your King Koil mattress exhibits one or more of the following material defects due to faulty workmanship or materials:

4. This guarantee is automatically invalidated in the following circumstances:

4.1 where the mattress is not used for its intended purpose as a mattress for sleeping on or is used in a manner contrary to our instructions regarding use.

4.2 where the mattress is used without reasonable care. A user will be considered to have lacked reasonable care in circumstances which include but are not limited to the following:
(i) use without bed linen;
(ii) use with an old or unsuitable bed base;
(iii) the mattress being, handled or otherwise dealt with improperly; and/or
(iv) any other treatment which could be considered to lack the requisite degree of reasonable care;

5.1 Any claim under this guarantee must be received within 30 days of actual discovery by you, or when you ought reasonably to have discovered the defect.

5.2 Claims should be made to Furnishings Warehouse by email.

5.3 Upon seeking to claim under this guarantee King Koil will ask you to supply photographs of the entire sleeping surface of the mattress and any visible fault. These photographs will be used to determine whether a replacement is necessary. King Koil is the sole arbiter of whether a mattress is faulty and qualifies under this guarantee. Failure to send sufficient quality or quantity of photographs of the fault may result in a replacement being delayed or the mattress not being replaced. We may also use our independent inspection agent to guide our decision to replace.

5.4 If King Koil decides that you are owed a replacement mattress the replacement will be delivered to you by our standard delivery method at no cost to you.

5.5 King Koil will either collect the faulty mattress upon delivery of the replacement, provided the collection address is in the country of purchase, or if agreed, arrange for you to return the mattress to us.
