Help in deciding on which bed type

Hi all,
I have tried to look through your questions but there are so many I figured it easier to email you for some more personal advice.
We currently have a Vi-Spring Devonshire which we have had for 4 years but due to our toddler and an accident we will be looking to replace this. My husband is 6ft and ranges from 15-16 stone and I am 5 foot 7 and currently 14 stone (although on a serious diet to reduce this) We would both fit into the medium tension. I love a soft cloud like bed but we went for medium on the Vi Spring due to weights (I'm not sure if having soft at my weight is asking for trouble)
What would you recommend from your range that would give this soft comfortable feeling? Would you recommend medium tension still? I'm assuming the Artisan range would be the best fit but wanted to get your expert advice first.
Thanks for your help
