An orthopedic mattress is a mattress typically made from memory foam or latex foam that helps people to sleep better at night. Having a worn out mattress is a threat to a supportive and comfortable night's sleep, as is having a mattress that simply is not capable of providing the best support for people that may have current orthopaedic needs.
Memory foam mattresses or orthopedic mattresses are very popular nowadays. Due to their ability to support the body while at the same time comfortably molding around it, they have fast become sought after not only by people that have orthopaedic complaints, but also by people that do not have any such condition but who wish to have a higher quality sleeping experience. Some people liken the experience of sleeping on a memory foam mattress as so comfortable that they feel as if they were sleeping on air.
