Latex is used to make a wide variety of products due to its unique elastic properties. It can recover its original shape after being compressed or pulled. Latex is used in the manufacturing of mattresses. For more information check the Top Ten Latex Mattresses from the web.

Tips for buying the best latex mattress
Comfort
As a sleeping surface, latex can be one of the most 
supportive and luxurious choices available. In addition to the comfort factor, many people choose a natural latex mattress due to ecological concerns, or because they prefer sleeping on a natural surface which does not use chemicals or synthetics. Latex mattresses are made in the natural form, in fully synthetic form, or using both natural and synthetic forms.
Firmness
For good rest, we want a bed that is firm enough, but not excessively so. Since our bodies are not flat surfaces, we need a sleep surface which conforms to the body shape to enjoy the best comfort during the night. If the bed is too hard or too soft, pressure points can build up, and we end up tossing and turning and being uncomfortable. A high-quality latex bed for many people is a great help in improving the quality of sleep.
Fair price
For many years latex mattresses tend to be expensive and also very heavy. However, in recent years advancements in foam technology have led to both lower weight and fortunately, lower cost.
Type of latex
A wide range of latex mattress sets is available. Excellent results are experienced with the 100% natural latex mattresses, or one can choose a combination type, such as those which contain a layer of latex and a layer of memory foam within the mattress. Memory foam also has excellent comfort properties, and in combo with a latex layer, one can have a very luxurious mattress.
Density
It should be mentioned that memory foam, although quite popular, is not suited well for heavier people. The person will tend to feel that he is sinking into the mattress. A latex bed averts this problem due to its having more elastic, springy, and resilient properties. Latex will tend to have a slightly firmer feel than a memory foam mattress, making it an excellent choice for those who prefer a firm bed.
Conclusion
Another good approach, for those on a tight budget, is to keep your existing mattress, but purchase a latex foam mattress topper and place this on top. This is not likely to be nearly as luxurious as a full latex mattress, but can still make the old mattress you have much more comfortable than it was.
