I cannot recommend what type of mattress is best for you, although many people like the comfort layer for its relative softness in comparison with the rest of the mattress. There are pros and cons for this: your mattress will certainly feel more comfortable, but that is only because the comfort layer has more ‘give’ and less proper support. If your back pain is not serious you may find a comfort layer suits you fine, but a firmer base definitely helps. You could try a thin topper first, and if that works for you then you don’t have to change the entire mattress.
