Exchanged items can not be exchanged again or refunded. The buyer has to ensure the good/s can be collected at the proposed collection date. The good/s has/have to be packed in their original or equivalent packing and has/have to reach us without any damage or dirt, in the same condition as it was received in. Therefore, we advise you to keep its original packaging. The cost of return or exchange has to be paid by the buyer and arranged by us. The cost of return or exchange of a mattress is GBP 90.00 The cost of return or exchange of the bed-systems, beds and any other furniture apart from mattresses is the stated delivery cost on the invoice.

17. The legal ownership of the goods will not pass to you until you have paid all of the money you owe us whether under this agreement or otherwise. You are responsible for the goods as soon as they are delivered to the site and we advise you to check your household insurance to ensure that you are covered.

18. We guarantee our Demko beds that we have supplied against defects in manufacturing for 5 years after the completion of the work. We guarantee our Demko mattresses and Demko bed-systems for 10 years, traditional bed bases for 2 years. This guarantee will only apply if:

I. you do not owe us any money under the contract.

II. you have properly cared for and used the goods and followed any instructions provided by us.

III. you write to us as soon as is reasonably practicable after discovering a problem that you wish to claim under the guarantee.

IV. you do not move the goods (excluding mattresses and beds) without our prior written consent.

This guarantee excludes electrical parts, zippers and glass.

V. The goods are placed/used on a completely straight, even and levelled floor/surface.

VI. The mattress is used on our slat bases or on straight, evenly supported slatted bed bases with around 2 inches gaps between their slats, which provides sufficient air flow for the mattress. In double and king size beds where 2 slat bases are used, there is no gap and/or a “V” shape between the bases. The mattress is used on an appropriate, strong, supportive base which is able to hold the mattress’ and its users’ weight without becoming hollow. The mattress is used in a bed frame which has frame around at a height of at least 10cm. Or if it is used on bases without frame around, we were told about it so we attach the layers by natural VOC-free resin.

VII. The mattress (and the Demko slat base if you have our bed-system) has been turned and rotated regularly. Whilst all mattresses will settle to some degree regular turning and rotating the mattress can reduce this. As you sleep in almost the same part of the mattress settlement  can occur quicker in that area than the rest of the mattress. Therefore, frequent turning/twisting and rotating of the mattress in the first years is important to even out the wear pattern to reduce and prevent settlement. Initial body impressions are not a fault of the mattress but an intrinsic part of the mattress bedding over time. Obviously, as you only sleep in an area the width of your body, the perimeter areas will be underused. Therefore, the sleeping areas are wearing quicker than the rest of the mattress but constant turning, rotating so using different parts of the sleeping area will eventually equal out this pattern. Mattresses that are full of natural fibres need more care and attention than cheaper cold foam or memory foam mattresses but they will last significantly longer.

VIII. Vacuum-sealed mattresses are opened within 4 weeks.

As a consumer you have statutory protection regarding faulty or misdescribed goods or inadequate services such as installation. These terms do not affect those rights.

19. Manufacturing tolerances on mattresses and their components’ sizes are +/- 3% on length and width, +/- 10mm on thickness from 0-15cm and +/- 20mm on thickness from 15cm-25cm. This variance in the size is perfectly normal depending on conditions and room temperature, and as such is not considered as a fault. All sizes quoted are for the finished mattresses. Variations in the density of the foams of +/- 5% are within manufacturing limits. Demko-UK Limited reserves the right to change the specifications of any product at any time. If your mattress fails within the specified guarantee period then we will either repair or replace the faulty component. We will repair or replace any product if it develops a fault within the guarantee period. Should that specific product no longer be available we will provide an alternative product of equivalent specification. What is not covered:

I. Wear and tear of fabric is not covered. However, we will use our discretion to see if any valid complaint is justified.

II. Wilful damage and neglect: Your mattress should be looked after and cared for. A mattress protector should be used at the very least. We will not entertain any claim if the mattress shows obvious signs of neglect.

III. Normal ageing or wear and tear including mattress settlement and “dipping” less than 3cm.

IV. Noises caused by the use of the product.

V. Repairs carried out by the persons not authorised by us or without prior approval.

VI. Shrinkage of mattress cover caused by washing or dry cleaning.

VII. The zip of the mattress cover and any other moving parts of the furniture eg manual head-lift.

VIII. Bespoke and items made to order with special requirements may have different features, appearances and may work differently than the standard items, therefor we do not offer guarantee on them.

IX. Natural ageing of the wood, which can lead to change in color.

X. Although organic latex is naturally anti-mould, anti-dust mite, anti-allergy, anti-microbial we can not guarantee they will not occur as it mostly depends on external factors for example: room temperature, dampness of the air, air-flow under the bed.

20. We can not be held responsible for any injuries, allergy and any other health related reactions/issues might be caused by our products. Our vegan mattresses contain Tencel and PES, our organic mattresses contain organic wool and organic cotton. It is the buyer’s responsibility to ensure they do not have any allergy or other health related symptoms to the components of our products.

21. All organic and natural wood and their natural finishing materials can smell. This smell is completely natural, harmless and will ease off in a couple of days or maximum few weeks.
