The Development of Memory Foam


Memory foam is a material that was developed by NASA. These days this material can be found in many homes. It is used in a variety of products, from sports equipment to mattresses. Originally this material was developed because researchers and NASA’s Ames Research Center were looking for a way to make the seats on rockets more comfortable and safe. In 1966 the result of their efforts was memory foam. It is a type of polyurethane. The material is mixed with other chemicals to increase its viscosity and density. NASA initially commercialized the material and then in the 80’s memory foam was released to the public domain.


At that time not a lot of manufacturers were willing to work with this material because the process used to make it was very complicated and unreliable. Thanks to the developments of technology and additional research over the years the process of making memory foam has developed greatly. Today the material is used to make memory foam mattresses, pillows, cushions and pillows for hospital beds. The mattresses and cushions that are made using this material are extremely comfortable and are very popular.There are two main types of memory foam: Low density and high density. Low density memory foam reacts to pressure. When an object applies pressure to the foam it moulds itself to the shape of that object. Once the pressure is removed the material regains its original shape. High density foam reacts to heat. If you are lying down on a high density memory foam mattress then it will mould itself to your body because of your body heat. Because the mattress moulds itself to your body it is very comfortable. It will give you proper support and is very comfortable to use

Initially because the process of making memory foam was so challenging, memory foam mattresses were too expensive for people to use. These days they cost less but they will still cost you a pretty penny. A brand new memory foam mattress may not fit everyone’s budget, fortunately there are mattress toppers available. A memory foam mattress topper is a cover made from memory foam that you can put on top of your existing mattress. The mattress topper is less expensive and will add a lot of comfort to your bed. If you are not ready for a memory foam mattress then you should consider investing in a memory foam mattress topper.

Katadyn For Filtering


When traveling and going on camping treks or visiting the forest or any such environment, it is essential to carry the basics  to make sure your trip goes well and that you are not left without a vital item. There are camping bags with the essentials  that come in the kit but most people make their own kits. One important thing to carry on such travels is water or then a  camping water filter. Water is no longer safe and clean for us to drink straight from the lake or stream, also we have become  used to to drinking treated water, and therefore any other type of water can have an effect on our stomachs. The camping  water filter will take out the bacteria and make sure the water is clear. Foggy water or dirty water too can be cleaned in  this way.


The filter is usually the size of a micron or smaller but is very efficient in filtering out bacteria that is to  blame for a lot of water borne diseases. This camping water filter can be used even for dirty water or cloudy water. There  are various models available some of them meet EPA standards which can be used for water in really bad conditions. Ideally  the filter should be able to filter about a liter a minute. This way there is ample water to use on the camping trip. The  camping water filter does not cost a lot now and its compact size makes it feasible to carry it on trips. It is easy to  handle and manage. The filter should be able to remove not only dirt but also the bacteria and its eggs making the water  drinkable.

Some filters may need iodine to be added to it, a carbon filter can be added to take off the bitter aftertaste of  the iodine in this case. Using orange juice crystals too can remove the bitter aftertaste. The orange juice crystals contain  ascorbic acid which oxidizes the iodine and leaves the water free from the bitter aftertaste. Katadyn is a famous name for  camping supplies and includes water filters for camping. The craftsmanship is really good. A katadyn product is of very good  quality and is longer lasting. Its technology is quite superior compared to the rest. It is a well known name when it comes  to camping water filters. Now katadyn too can be found on online stores with great offers and free delivery.
