There are a number of different types of futon mattresses on the market. A futon mattress can be filled with several different materials and has a set level of firmness as well.

Probably the most important aspect of a futon mattress is its filling. The type of filling will determine the firmness and lifespan of the mattress. There are several different fillings to choose from. A futon mattress can be filled with cotton, foam and cotton, innerspring, or foam. Cotton is the most economical, but it also loses its firmness and is more absorbent than other fillings. Most futons are filled with a mixture of cotton and foam. This mixture lasts years longer than pure cotton. The innerspring system is a set of springs surrounded by either cotton or foam that is somewhat similar to a traditional mattress, but thinner. Many high-end futon mattresses are made of latex foam that can contour to the sleepers body.

Like conventional mattresses, futon mattresses come in soft, medium, and firm. The firmness depends in part on the filling. It is recommended to purchase a futon mattress that is more than six inches thick. The level of firmness does not reflect on the quality of the mattress, just the preference of the user.

Discount futon mattresses are available online and at many retailers. These futons can be as good as ones purchased at full price. When purchasing a discount futon mattress it is important to know what it is filled with, as some materials last longer than others. Often, high quality futon mattresses will be sold at discounts to make room for new merchandise.

Futon mattresses are a great alternative to conventional spring mattresses. They have comparable firmness and size at a fraction of the cost.
