We have two ranges of Pocket Sprung Mattresses, our Origins Range which have man made fillings and our Artisan Range which have natural fillings. However as you are a hot sleeper, you would be better with a mattress that does have natural fillings as you should not overheat on this type of mattress.
In the Artisan Range, if you prefer a firm mattress you would be looking at the Artisan Bespoke as this is the firmest mattress that we make in the upholstery layers. At your body weight however, I would recommend a medium spring tension as this will give you the correct support.
With a Pocket Sprung mattress, the springs are there to give you the support and your body needs to move with those springs in order to give you that support. At your weight and height, I would recommend a medium spring tension which will give you that correct support.
If you require any further assistance, please do not hesitate to telephone our office on 0161 437 4419.
