Memory foam mattresses are one of the more expensive types. This type of mattress has varying support and firmness across the entire surface, with softer points near the head of the user and firmer support along the lumbar region. Movement in one section of the memory foam does not cause disturbance to the other sections. Note that memory foams are highly combustible because they are made out of polyurethane. Other memory foam variants allow for better airflow through the mattress and to the user.
Spring-type mattresses are one of the more common types, made up of a spring core, the foundation and the layers of upholstery to serve as the main cushion of the mattress. Cheaper mattresses use Bonnel coils, which look like hourglasses stacked side by side. More expensive mattresses that provide fewer disturbances from one side of the mattress to the other make use of Marshal coils. These are individually wrapped coils, which dampen motion.
Air beds or air mattresses have a single chamber filled with air. This type of mattress is the most portable because you can deflate it and transport it easily. This makes it a good choice as a spare or guest mattress in your home. Air mattresses come with air compressor pumps to help you inflate the mattress. Some air mattresses have varying pressures depending on the location in the mattress to provide better support for the user.
The thickness of a mattress determines the level of comfort it gives to the user. But because not all users have the same requirements, different mattress thickness is still not a single factor to determine of a mattress is best for you. Thinner mattresses supported by solid wood bases, such as those from 6 to 8 thick, are good for those who need back support. Memory foam mattresses often come in 10- to 14-inch variants.
