If you compare the pricing of memory foam mattresses to spring mattresses, memory foam mattresses are certainly the costlier lot. But, they also get top rated reviews.
Spring mattresses are cheaper for obvious reasons, their manufacturing techniques are very basic. Memory foam mattresses, however, make up for this handicap with longer warranty periods. Foam mattresses with 20 year warranty are pretty common. If you use them carefully, you can sleep on them for years to come.
Keeping The Body Cool While Sleeping
The first versions of memory foam mattresses sometimes heated up the body too much while sleeping. But the newer foam mattresses have started to use patented technology to maintain airflow while sleeping which takes care of the overheating problem quite efficiently.
Apart from all these benefits, memory foam mattresses are manufactured from non-hazardous bio elements which reduce their carbon footprints to a large extent. If you are worried about the environment, memory foam mattresses are the best bet.
