A poorly designed bed can induce pains and aches in different parts of your body. If you are having such pains for a long time then probably it is time to take a look at air mattresses. These innovative beds can support your body weight perfectly and they do not put undue pressure on any part of your body.
As these beds use air, they can support the body evenly. At no point of time your back will be arched in an uncomfortable position. Some of the new air mattresses even come with sensor air pumps that automatically inflate the mattress if it starts to lose air during the night. Hence, as explained here, these are the best beds for good health.
If you want more information about air mattresses and their benefits, take a look at NIH and /or Sleep on Air . Once you sleep on one of these, you will never go back to traditional beds, ever.
