The perimeters of the coils are connected to a wire which surrounds the mattress. At the edges, special springs are used for better support and top layer of mattress has insulation or tough padding for separation from the springs present below it. There could be around 300 to 800 coils inside the mattress which depends usually on its size.
The Air mattresses have flexibility for adjusting the level of comfort by altering the firmness. There are air mattresses with dividers so that air levels in both sides could be adjusted. They are portable and especially used for outdoor trips, camping and also in hospitals for patient beds.
These mattresses were manufactured initially for NASA astronauts during 1970, to relieve them from pressure due to gravitational force exerted during the time of takeoff of spaceships. They can get compressed when pressure is applied and return back to normal stage once pressure is removed.
