While individual preference is probably the most important factor in determining the best 
mattress for each person, there are some general rules of thumb in what constitutes a good mattress.- In general, most people prefer a firmer mattress that gives the spine more support. While there is no definitive literature thatabsolutely supports this claim, it makes sense that it is beneficial to have support for the spine while sleeping. It is thought that a mattress should provide support for the spine at all points (along the spine’s natural curves), and keep the spine in the same body position as good standing posture.
