Spring mattresses are constructed with a foam or fiber layer on top and coiled springs underneath, providing a bouncy feel. These traditional mattresses were in common use for decades, and many still prefer them over the newer memory foam or latex options.  However, due to these springs, this type of mattress cannot adapt to the shape and weight of the body very effectively. These springs can also bend over time and lose shape, reducing your comfort levels.  On the other hand, a memory foam mattress generally does not contain springs, except for hybrid options. These mattresses adjust to the shape of your body more effectively, providing better support and comfort. Also, such mattresses can isolate motion and provide excellent pressure relief more efficiently than spring ones.  Latex mattresses are among the most eco-friendly of these three options since they are made from rubber instead of harsh chemicals. They are also highly breathable and can regulate temperature easily to keep you cool during the night. Additionally, unlike foam mattresses, they do not have off-gassing or odor issues.
