Good mattress for back pain

[carboy2017]

I suffer from back pain time to time and i suspect the mattress is not helping as its sagging a bit now and too soft in the middle, when i went off on hols and used a harder mattress it was fine

Can you folk suggest a good mattress that is firm and not too soft and good for the back?

Theres no substitute for getting down to a bed/mattress shop and lying on a few to see whats comfy.

You could spend a few hundred or several thousand to find the right one. Its all down to your back.
