Most people are unaware that their mattress is old and doesn't provide enough support, doing you more harm than good. If your mattress disturbs your sleep, so that you feel some firm details or even springs under the fabric and cushioning, then it's definitely the time to it and shop around using mattress ratings and reviews as a guide.

A good mattress does more than providing you a soft comfortable place to rest after the long day or a place to cuddle with your loved one. The right mattress may actually improve your sleep and posture keeping your spine in the right position for seven to nine hours.

If your sleep is worse than it used to be a few months ago, check for signs of mattress deterioration. To determine whether you need a new mattress, take note of any stiffness or sore muscles or joints when you wake up in the morning. Any friction of the fabrics, unusual sounds and if there is a noticeable dip formed by one or two sleeping bodies on the mattress will tell you that the mattress needs to be replaced.

Most mattress ratings consider such attributes of a mattress as thickness, the material the mattress is made of, a warranty, price point and special features such as hypoallergenic qualities, stress-relieving design, and the fabric of the covering. After carefully studying the customer reviews and mattress ratings, this is what most people look for in a mattress:

1. The material.

Organic cotton and soft wool have become very popular among health-conscious buyers. However, cotton and wool mattresses are not treated with fire-retarding chemicals required by law. The mattress should not contain any polyester fillings and should be made of pure wool, preferably lamb or alpaca wool or at least latex foam. The perfect mattress should be dye-free, dust mite repellent, hypo-allergenic and anti-bacterial. Ideally, the mattress should be moisture repellent and flame resistant, too. The mattress should be encased in unbleached organic cotton. Memory foam mattresses are highly rated as the most suitable mattresses for allergy sufferers, but some people suggested that these mattresses become stiffer in a hot climate.

2. The shape.

Firm mattresses provide more support and the most upscale models are doctor-prescribed. In general most reviewers prefer soft and thick mattresses which provide more comfort. The most common wish is that the mattress should regain its shape and should not flatten over time. People highly rated mattresses that are durable and are likely to last many years.

3. The size.

Most mattresses reviewed in mattress ratings are available in twin (single), double, queen, king and Californian king sizes. In general, people prefer to buy a mattress from a manufacturer that offers all imaginable sizes.

Your mattress foundation is also important. Ideally, you should get it from the same manufacturer because it will prolong the life of the mattress. When properly chosen, mattress and foundation will keep your spine healthy and naturally curved, ensuring you have a good sleep and pain-free morning. After a good night sleep on an orthopedic mattress your sleep will become deeper, and you will have much more energy during the day.
