Sciatic nerve pain is awful, it occurs when the sciatic nerve gets pinched by the lumbar disc. Generally, the symptoms include pain, difficulty sitting, weak legs, tingling and trouble sleeping. If your mattress is too soft or too hard, then it could be making your sciatic pain worse. The ideal mattress is one that is supportive yet supple, one that holds your body, but is not to rigid.
Most spring and foam mattresses are no good as they do not provide the right balance bet support and comfort. If they are too soft or hard, then your body will strain during the night because your spine is not in an optimal position. This will increase the pressure on your sciatic nerve, making it more painful.
Because memory foam shapes itself perfectly to your body, your spine will be in perfect alignment all night, no matter if you move, thus removing the pressure from your sciatic nerve. Memory foam reacts to body heat, shaping itself specifically to your unique contours.
If you suffer from sciatica then you should consider getting a memory foam mattress as it will make the world of difference. You will sleep better and you will wake feeling better.
