However, the isolation of your sleeping partners movements can be minimized by utilizing innersprings in a unit that is wrapped with layers of foam, particularly memory foam that conforms to your body shape. This not only offers you maximum comfort while sleeping, but also helps to reduce night sweating that can be very uncomfortable. You can also lay the mattress on a box sprung unit that offers a secondary source of comfort.
There are several memory foam products available on today’s retail markets and each of these mattresses includes a denser than standard foam composition. These mattresses can be sold at higher prices than traditional mattress products and each foam mattress is measured by the foam’s indentation force deflection. Each mattress can have a soft or firm feel and each has its own indentation force deflection rating. A higher deflection rating will feel firmer when compressed.
