Your budget may also limit your options . The more money you spend , the more comfortable you will be , regardless of whether you ’ re on foam or springs . If you ’ re working with limited finances , you ’ re more likely to find a comfortable and durable spring mattress in your price range than a memory foam mattress . Of course , prices vary from place to place and time of the year , so be sure to do some extensive research before money changes hands . A good mattress will pay for itself many times over .
