Arguably one of the best types of mattress is the memory foam mattress. These mattresses feature memory foam which was originally developed to relieve the pressure that astronauts experienced when travelling into space. Due to the benefits this material possessed it soon became apparent that they would be ideal as household mattresses.
The main benefit of memory foam is the ability to adapt to body temperature. This allows the spine to remain aligned correctly during sleep and relieve pressure points that are often found when using other types of mattress. Memory foam is available in a variety of thicknesses, which effects how comfortable the mattress might be. A thickness of around 3 to 4 inches is recommended for most individuals, but be wary of cheap mattresses advertising 8 or 10 inch thicknesses. You may find that they are including other materials in this measurement rather than just the memory foam.
