Memory foam was developed by NASA in the 1970s, but became known in the consumer market as topper pads. Later, in the 1990s, the memory foam mattress was introduced. From then until now it has occupied a very prominent place in the mattress industry.
Sleeping on a memory foam mattress is considered good for people with back problems, arthritis, bone and joint problems. Memory foam mattresses are available in a range of sizes including single, double, queen, king, California Queen, California King and Super King. Some double memory foam mattresses have both a softer and a harder side to meet the needs of sleeping partners. In most cases, the density of a shape memory foam mattress is about five inches.
There are certain points to consider when buying a mattress with shape memory foam to ensure that you get the mattress of your choice.
Choosing the right type of mattress with shape memory foam is really a very important decision. The following tips can really help you when buying such a mattress.
Mattress with temperature sensitivity
It is not necessary that all mattresses available on the market are temperature sensitive. However, this property of the mattress should not be underestimated as it is very important. This is the property that makes a mattress with memory foam unique and absolutely comfortable.
If you are looking for a mattress and you come across a mattress that can adjust to the temperature, you should buy it. In a warmer environment this mattress will absorb the body heat. It will also become softer. Similarly, it will become firmer in a cooler environment.
Mattress with the right thickness
The thickness of the mattress is one of the important points to consider. It is the thickness of the memory foam that plays a role in buying the right memory foam mattress. The thickness of the shape memory foam can be defined as the total weight of the mattress, calculated in one cubic foot of shape memory foam. For example, if you want to cut a piece of shape memory foam into a 13×13×13 cube and then weigh it. The resulting weight is therefore counted as the thickness of the mattress.
There are various theories about the correct thickness of a mattress made of shape memory foam. However, it is always better to choose a mattress with a thickness of 5.3 to 5.9 pounds, because a memory foam mattress with a thickness of less than 5.3 pounds will not be able to support your lower back, shoulders and hips properly.
If the memory foam mattress is more than 5.9 pounds thick, it is also too thick to provide adequate support.
Mattress with sufficient cover layer
When you buy a mattress with shape memory foam , it is important that you choose a mattress that has enough shape memory foam on the top layer . In general, it is best to choose a mattress with 3.5 inch memory foam as the top layer.
If the layer is too thin, it is like sleeping on polyurethane foam in this case. It is quite possible that you will not sleep comfortably on it.
