Looking for a bed for person who is 13 stone and has a bad back?

I have been looking for a mattress for the past 12 months my older bed is 15 years old.

I am 13 stones with a bad back and i have tried and tried all sort of bed from £200 to £1200 and i am total confused with the choice i have.

My problem is all the beds i tried all seem wonderful but it is not until you get it home and sleep on it that you then decide if it suits.

this is the problem i have.

Any sugestion would be helpful..

I found the springs/" title="pocket spring">pocket spring ones seem to suit the best for me.
