Mattresses are supposed to provide adequate weight support, specifically for the spine. To avoid sore muscles and cramps, find a mattress that supports the body’s curve in a neutral position. Make sure that the heels, buttocks, shoulders and head are properly aligned. This way, discomfort is eased by enough support on the body’s so-called pressure points. For the most part, however, selecting a mattress relies on personal preferences, which shouldn’t always be the case. Some people, indeed, prefer picking a firmer mattress because of the “back support” features, but somehow end up with muscle cramps in the morning.
In selecting your mattresses, keep these two things in mind: support and comfort. A mattress with enough inner springs or coils is your best bet as they provide adequate support for the spine, while also allowing for its natural curves. For comfort, take close note of the padding and the material used for it.
