Mattresses are often thought of in terms of comfort. The right amount of firmness or softness, the right amount of plush, and the right amount of support are the most common concerns that mattress shoppers have. But the amount of cross-motion that a mattress has is also an essential consideration.
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.
Serta is the second most recognised brand of mattress and has the industry's lowest return rate. And the Serta Perfect Sleeper mattress remains a best seller. This all sounds fantastic but Serta's Perfect Sleeper uses the same manufacturing principles, technology and materials that have been used in manufacture of mattresses for many years. There's a concern that other mattress manufacturers essentially make the same mattress but at a lower price, or make more technically advanced mattresses at prices to match the Perfect Sleeper mattress. So, let's take a closer look.
Foam technology was actually developed by NASA back in the 70's and after they discarded the concept the medical industry took an interest in it. The thought was the foam cushioning would help prevent pressure sores amongst hospital patients. Eventually as the foam technology improved and overcame obstacles with durability and cracking it led to the production of household mattresses with foam tops similar to that found on a king pillow top mattress in the 90's. Today you can buy a whole king foam mattress that utilizes the latest technology in foam.
