10 Year Guarantee

10 year* Guarantee

The warranty covers physical defects and changes that cause visible, permanent depressions (of more than 2 cm (5cm for Sprung)) in the Memory Foam Material of the sleeping surface. The warranty does not cover ordinary changes in hardness or characteristics that do not affect the pressure-relieving properties of the product.

It is quite normal for the foam to discolour from the near white to a shade of yellow. The warranty is only valid if the HYPNIA product is used and handled as described in the instructions provided for the product.

In the event of a complaint, please show/send in your invoice or receipt as proof of purchase. Customers will also be expected to comply with the companys requests for evidence to support any such claim; whilst typically photographic via email, this may be needed as physical evidence.

This warranty does NOT apply to any covers provided with the product or the mattress base layer.

The Hypnia warranty covers the memory foam item only. It does not cover any Shipping / Carriage costs for either the return of failed goods or for the sending of replacement goods.


*Pro rata

0-5 years: full warranty (on memory foam layer).

6-10 years: warranty reduced by 20 per cent per annum


Warranty replacements are at the discretion of Hypnia and we reserve the right to withdraw or amend the warranty at any time. Warranty replacements may at our discretion be of only the memory layer not the entire product and will be made with the nearest possible specification, if the original is no longer in production. Only one warranty replacement is available per order. Note that a replacement item does not extend the original warranty period.

All items must be released from their compressed state within 2 weeks of delivery or the recovered size may vary from that advertised and will then be excluded from any warranty.

Our guarantee only applies to goods delivered to mainland UK. If the goods are removed from mainland UK and you wish to claim under the terms of the guarantee, you will be responsible for any additional shipping costs.

This does not affect your statutory rights.
