Choosing the right mattress really depends on what you like. If you're looking for a large two person bed and you have an average body density, then you might want to try out the medium firm latex mattress. Perhaps you just want a bed for yourself that you can sink into and feel extremely relaxed. The full memory foam mattress might be a better choice here. By looking at the different varieties of mattresses, you can narrow down your list to the exact mattress that you want to buy.
