Not too many years ago, there were few options for consumers to choose from when it came to mattresses.  There were inner-spring and box spring mattress sets and in the 70's came a hip alternative; "water beds". It seems that the old water bed started a revolution in sleep that has continued for decades. Technology has brought many new options besides just water, and metal springs. The latest trends are all about air, no not your old blow up vinyl mattress mind you, but various types of foam ranging from vinyl to "memory foam". Open cell "memory foam" allows air to enter and escape tiny chambers from within the foam. Memory foam was developed in the NASA space age, and has created a new revolution in mattress technology.  By itself or integrated with other technologies to create hybrids or combinations of various types of foams and air chambers, memory foam has many advantages to consider.

So what does all this mean to you?  Greater comfort and relief from pain for starters.
