The answer is yes if you're a preferred back sleeper or of a heavier stature. To be supported whilst sleeping on your back, it's important that your spine doesn't sink into the mattress. This would mean that the spine is aligned incorrectly and can cause aches and pains. For those who are heavier than the average person, the twice tempered springs in this mattress mean they are stronger, therefore fully supporting and evenly distributing your body weight. This ensures you wake up feeling supported and you can wake up without aches or pains. Front sleepers should opt for a firmer, maybe instead of an extra firm, mattress to ensure that the neck and spine are aligned correctly, even though more pressure is added to these areas of the body by sleeping in this position.

No, the foundation of support comes from the spring system. Anything added to this doesn't take away from the springs support, but adds to other qualities like comfort or durability. In this case, the memory foam layer contributes to the overall comfort of the mattress whilst you receive the ultimate support from the springs. Leaving you to wake up feeling fully supported and refreshed.
