Origins King size mattress dimensions in cm

Hi Ed,

Thank you for your question.

Please visit this link for details of the mattress sizes and weights .https://johnryanbydesign.co.uk/understanding-beds/mattress-sizes/

If we can assist you with regard to this mattress, please do not hesitate to contact our office on 0161 437 4419.  We would need to know body weights, heights and preferred feel as the springs in a mattress are for the support and the top layers are for the comfort.  The Origins 1500 has a medium spring tension which covers a large range of body weights together with an overall medium comfort layer meaning the mattress is neither too soft nor too firm.

I hope this assists.

Kind regards Julie
