2.7. Klarna:
3.1. Delivery times will depend on the item and the manufacturer. If your item is out of stock, our delivery lead times will be clearly detailed on the product page.

3.4. MattressOnline.co.uk Ltd are only responsible for delivering goods to the customer's door.

4.1. MattressOnline.co.uk Ltd takes great care to faithfully reproduce all descriptions and specifications as provided by the manufacturers, however, errors may occur. If you are in any doubt, we recommend you contact our Customer Service team to discuss the item in more detail.
4.2. The illustrations and colours are representative only.
4.3. All sizes are correct according to the manufacturer's specifications.
4.4. All items are subject to availability.
4.5. All details, specifications and prices are accurate at time of publication, but may subsequently change. While we make every effort to ensure that the mattresses shown are as close as possible to the actual specification and size, there may be slight variations due to the nature of the medium.
4.6. We reserve the right to alter specifications as advised by the manufacturers.
4.7. Responsibility for checking the dimensions of your bed or mattress lies solely with the customer. MattressOnline.co.uk Ltd cannot be held responsible for customers ordering the incorrect size or not checking the dimensions before purchase.
5.1. There are no lawful guidelines for sizes of beds that have to be used. The size of the product used is for descriptive purposes and there is no assurance that these sizes will be exactly the same across different manufacturers.
5.2. For instance, a double mattress from one manufacturer may not exactly fit a double divan from a different manufacturer.
5.3. Additionally, please note that mattresses are hand made with many individual components. As such, it is not always possible for a manufacturer to produce an exact size. This is especially the case for pocket sprung mattresses, where the free movement of the springs can marginally alter the overall size of the mattress. For this reason, it is necessary to allow a +/- tolerance in the depth, width and length of your mattress. Although this tolerance depends on each individual manufacturer, as a guide we suggest an allowance of +/- 1 inch (2.54cm).
5.4. Please be aware that when converted, metric sizes are not exactly the same as imperial sizes. Below are all the sizes of mattresses we sell and beds that fit these sized mattresses:
| Size | Imperial | Metric |
|---|---|---|
| Small Single Short | 2'6" x 5'9" | 75cm x 175cm |
| Small Single | 2'6" x 6'3" | 75cm x 190cm |
| Single Short | 3' x 5'9" | 90cm x 175cm |
| Single | 3' x 6'3" | 90cm x 190cm |
| Small Double | 4' x 6'3" | 120cm x 190cm |
| Double | 4'6" x 6'3" | 135cm x 190cm |
| King | 5' x 6'6" | 150cm x 200cm |
| Superking | 6' x 6'6" | 180cm x 200cm |
| European Small Single | 2'6" x 6'6" | 75cm x 200cm |
| European Single | 3' x 6'6" | 90cm x 200cm |
| European Double | 4'7" x 6'6" | 140cm x 200cm |
| European King | 5'3" x 6'6" | 160cm x 200cm |
