In short, it's a bed without legs. This makes you feel like sleeping on the floor with an air filled sleeping bag. True, it does serve its awesome purpose of an extra sleeping unit for guests and you can take it along with you when you go camping or traveling. It is much more comfortable than sleeping on the couch and a curling up in a sleeping bag on the floor or the ground. However, air bed manufacturers have come up with a better design with the raised air mattress. For ease and comfort, it is made with stands or legs that props up the bed making it look like your typical raised bed. The evolution of the mattress started thousands of years ago. One thing to note is around 3000 B.C., cavemen were smarter than the stereotypical Geico commercials we see today. Back then they would lay stones on the ground and cover them with animal skin to use as a bed. However, we want to start the evolution around the 1800s when mattresses were nothing more than sheets packed with feathers. Memory foam mattresses, on the other hand, are different from the traditional spring type and the air mattress because of the material used to make it. This is so because it utilizes foam although it isn't exactly the regular foam used for other purposes. It actually utilizes a 70's foam innovation given that memory foam mattresses are generally visco-elastic, i.e. almost like airbeds, the foams appropriate body shape and weight yet, comes back to its original shape when body pressure is removed. In this mattress review, one finds out that the said mattress actually provides for comfort, support, durability and a lot more.
