Terms and Conditions

Authenticity of King Koil Products

Matsushita Greatwall Corporation Pte Ltd is the exclusive manufacturer and distributor of King Koil mattresses, bedframes, sofas and bedding accessories in Singapore and Brunei. We can appoint retailers to authorised distributors to distribute our products in these territories.

It has come to our attention that there are King Koil products that are sold through retailers that have not appointed as King Koil’s authorised distributors. As such, we are unable to confirm the authenticity of these products and to provide after sales services.

We would encourage you to purchase King Koil products from the King Koil Flagship Galleries, Department Stores, Furniture Stores and Authorised Distributors. You may check the following link for further details.

If you do have any queries, our retail sales assistants or authorized distributors will be able to assist you. Alternatively, you may also contact us at (contact us page).

Terms and Conditions (for purchase made on our online store)

Payment Methods Payment for all orders sold on our website can be made online with a credit/debit card via a third-party website.

Cancellation, Refund and Exchange Policy

Strictly no cancellation and refund are allowed upon receipt of payment. Due to hygiene reasons, we will not accept any returns of toppers, bedsheets, quilt covers, quilts, mattresses and pillows that have found to be used, stained, torn, washed, and/or with traces of fragrance or odours. For items with defects upon receiving, we are unable to accept any exchange unless the product is returned in its original packaging and condition.

Delivery and Lifting Charges

Free delivery is applicable to the following order that occur in a single invoice, to a single address in one trip:

Purchases will be subjected to a S$6.00 delivery surcharge if the total cost amounts to below S$100.

In the event that a single order has to be split into various delivery dates/locations/timings due to special requests and/or selection of delivery dates within the stated delivery lead-time period, all additional logistics charges will apply according to the above-stated guidelines, with each timing per location considered as an individual order.

Free delivery is only applicable within Singapore mainland between 11am-8pm from Mondays to Saturdays, excluding public holidays. A surcharge of S$30 is applicable for delivery to Sentosa Island. We do not deliver to Jurong Island and Army Camps.

In the event that the goods cannot be delivered on your preferred delivery date and/or timeslot due to reasons such as lack of stock from suppliers or scheduling difficulties, you will be notified the soonest possible, we reserve the right to amend the delivery timings or to substitute the item model for a similar product of higher or equal value should such circumstances arise.

To qualify for free delivery, your delivery location must be accessible via elevator (i.e. on the same storey as lift landing) or must be on the same floor as the goods loading/unloading area.

If the delivery team is unable to send furniture to your location via the elevator at the point of delivery (eg. Furniture is unable to fit into elevator, elevator unserviceable upon delivery crew’s arrival, refusal of elevator access by building management etc) we will assess (at our own discretion) the feasibility of the furniture being carried up via the staircase in a non-hazardous manner. A lifting charge of $10 per level (after the 4th floor) will be applicable for such services. The lifting charge is to be made payable to our logistics team.

If the process is deemed hazardous, (e.g. furniture or infrastructure prone to damage on narrow stairway, obstruction of passageway), and delivery is deemed unfeasible, SleepWell.SG reserves the right to cancel the delivery. Upon cancellation, a refund of any of your prior payments for that delivery will be made by cheque within two weeks from the initial delivery date.

Delivery Dates and Timing

Upon confirmation of your order, we will be in contact you (via email or phone) to confirm the delivery date and time.

You’ll be contacted again an hour before delivery by the delivery team to confirm your presence at the delivery location and to notify you of our impending arrival. While the delivery team will try its utmost to deliver within the selected time frame, there are many external factors which can cause delays. Furniture is large and heavy and the delivery team may face difficulties in moving goods up narrow stairways. Traffic, vehicle and weather conditions will also affect the delivery time, as we want you to receive your order in the best condition possible. Customers who are not present upon our arrival also cause delays that can stretch for hours and hold up all the following deliveries.

We earnestly urge all to be present during the stipulated delivery time to be considerate to all other customers and seek your understanding when it comes to delivery timings.

We reserve the right to change the delivery date and time should any unforeseen circumstances arise in the midst of delivery. While we endeavour to adhere to scheduled delivery timings and warrant to act within our means to notify you the soonest possible of any delays or difficulties, you acknowledge that you will, at no point in time, hold us liable for any inconvenience, losses, damages, injury, charges, expenses and/or deaths that may arise from any delayed, postponed, incomplete or unfulfilled deliveries, to the extent permitted by Law.

Free Disposal of Old Mattress

Free disposal of your old mattress is available with the purchase of any mattress. This service is available if you have selected the option on the online order form and only if the location of the old mattress is identical to the delivery location of the new mattress. The delivery team will not be able to dispose off the old mattress due to scheduling constraints if prior arrangements have not been made. We do not dispose of other forms of furniture, as we do not have the resources to break down and dispose of old furniture in authorised locations as specified by local authorities. We advise you to contact your town council for free furniture disposal service (HDB or landed estates), or your condominium/office building’s building management. We reserve the right to refuse disposal of any old mattresses at its full discretion.

There will be strictly no disposal of old mattresses which are infested with bedbugs or other pests. This is not only to protect the health of our staff, but also to protect the other new mattresses and furniture that are still in the lorry from similar infestation.
