Thank you for your enquiry. The spring tension in our mattresses is soley determined by your body weight. This is what support you through out the night. If you are too heavy for the springs then they will be too compressed to offer any support. If you are too light for the springs then they would not move at all and the comfort layers will be crushed between you and the springs and not be able to offer any comfort. At your body weights we would recommend a medium tension in the springs.
The ‘feel’ of the mattress is determined by the upholstery layers. This is subjective to each person as what is comfortable to one person is not comfortable for another. If you want a soft feel mattress then take a look at our Origins Comfort 1000 or the Artisan Luxury which are both the softest in there ranges.
Hope this answers your question but if you require any further information please do not hesitate to contact us on 0161 945 3757.
