You spend seven to eight hours lying on a mattress. That much time means that your choice of mattress plays a huge role in how your back is going to feel when you wake up, not to mention your overall health as well. A mattress has to do more than just be comfortable enough to sleep on—it also needs to ergonomically support your whole body structure.
If price and savings are your prime consideration when choosing a mattress, you might want to reconsider your options. Think of your mattress selection as an investment in your health, so you need to choose the best mattress available. Then again, “best” here is a subjective term, and in that case, you need to find a mattress that suits your physicality and personality perfectly.
