Memory foam is popular because it is supportive, comfortable and known to help those who struggle to get a restful night's sleep. Memory foam is usually made from visco elastic foams that contour to your body. The more dense the foam is, the firmer the mattress is. However having a dense mattress also means it will last longer, and some of the problems associated with low density memory foam is that they tend to stop working sooner and potentially cost you more money in the long term. Density also matters in relation to your body weight too, so when choosing a mattress make sure it can withstand your weight!
What is interesting is the SpiraLok Technology used in the Restonic mattress. Basically, it's a tight steel weave that locks the coils together. It's claimed that this reduces motion transference and thus decreases partner disturbance. In total contrast, the Simmons Beautyrest mattress uses pocketed coils - springs that are not joined together but are kept separate in their own fabric pocket. So, who's correct? In my view I can't see how a traditional innerspring mattress can claim to reduce motion transference; pocketed coils help but they have drawbacks. If you really want to eliminate motion disturbance, you need to opt for either latex of a memory foam mattress - which both Simmons and Restonic offer.
Air channels through the mattress so you never feel hot or overheated. Once you use a memory foam mattress, you'll never go back to an inner spring mattress again.
Memory foam, also often called temperature-responsive foam, reduces cross-motion without special engineering. This is because memory foam was originally designed by NASA scientists to absorb energy instead of transferring it. Because memory foam mattresses are very dense, yet viscous, movement on one side of the bed does not create a wave effect on the other side. For the same reason, memory foam mattresses are very difficult to bounce on-- they simply absorb the energy and do not transfer it by bouncing back in a springy fashion.
