You can choose a perfect match to your requirements from the numerous options of bedroom mattresses available today. One of them is foam bedroom mattresses which were originally devised for NASA astronauts in 1970 as a solution to the gravitational pull experienced while spaceship take-offs. A decade later these mattresses were launched in the market for masses as well. The foam bedroom mattresses can be found in three different kinds of materials, i.e. Viscoelastic, latex or polyurethane. Viscoelastic bedroom mattresses also popularly known as memory foam bedroom mattresses are durable, albeit a little expensive. Latex bedroom mattresses are more popular owing to their quality of creating warm conditions for the sleeper in winters and cool conditions in summers. Also, latex bedroom mattresses are highly recommended for asthma patients as they have the ability to repel dust.
