Hi Liz

Thanks for your question.

I would recommend that you take a look at the Origins Comfort 1000 mattress and also the Artisan Luxury. These 2 mattresses have the softest upholstery in their relative ranges, so these are the ones you sink into the most which is great for side sleepers, so it doesn't create any more pressure.

The Artisan Luxury will be the softest model out of the 2 and being made up of 100% natural fibres means it will be overall a cooler mattress, than the Origins Comfort which is entirely man made fibre fillings, these will be a little more heat retentive.

At your body weight we would recommend a medium tension spring in both models, the Origins range come as standard with medium springs, and the Artisan range you would choose a medium tension spring.

If you require any further assistance please call the office on 0161 437 4419.
