When deciding on a product to buy, it helps to know your options so you will have an idea on what to look for. If you are on your way to buying a new bed set, you should know what choices are there. There are different types of mattresses to select from. These are: innerspring which uses coil springs for support; memory foam that has a delayed form-fitting responsiveness, which in turn forms itself to your body shape; latex which is similar to memory foam in terms of support and durability but is less conforming and returns back to its regular feel; air beds which are associated with innerspring but use air instead of coils; waterbeds that make use of liquid instead of coil to support the structure; adjustable which as the name suggests can be flexible, can be bent and elevated; and dual purpose beds such as sofa beds and futons.
