The memory foam mattress is the most popular and most recommended by experts. But if you do not make the right choice when it comes to the thickness and density of the mattress then all the research that you did and the money you invested goes waste. More often than not, while shopping for a memory foam mattress people believe that bigger or thicker is better. It is not the case as a memory foam mattress has many layers and when they all add up together it impacts the mattress height.
Do the thickness of the mattress impact comfort?
The common myth among most shoppers is that the thicker the mattress the more comfortable it is. Contrary to this more thickness does not mean comfort. It has got to do with the types of foam used and the different layers used in its making. Instead of looking at the thickness of the mattress, density should be taken into consideration. Comfort is a personal preference and varies from person to person.
Difference between density and thickness
Most salespersons confuse density and thickness when selling a mattress. The thickness refers to the mattress height and the memory foam density which is measured in kg/m3 is defined as the mattress weight and volume. Typically, the higher the density better the quality and is harder, firmer and more durable. Whereas a low-density memory foam offers less support and is softer.
The thickness generally changes with the number of layers that are present in the mattress while density is defined by the solidity when these layers are put together. It is best to choose a memory foam mattress that has a density rating of more than 3 pounds per m3 of foam layer as anything below it will not give enough support to the body. Many leading online manufacturers like Wakefit offer high-density foams on their memory foam layer and thus are good for body support. The thickness can range from 3 to 10 inches.
Factors that determine the mattress thickness
Bodyweight: The body type of sleeper is one of the determining factors in finding the perfect thickness. A simple formula is the more you weigh the thicker the mattress you should buy for better body support. When choosing a mattress always give consideration to the weight it will support. A thicker mattress is a better option for couples while a single sleeper who is petite can sleep well on the thin mattress too. Also, ensure that the thickness does not make it difficult to get in and out of bed.
Mattress layers: Most memory foam mattress composition remain the same with the bottom layer made of heavy and solid foam to support the other layer. Then there are the transitional layers usually made of polyurethane foam and then there are the top layers also called as the comfort layers which vary. Thicker mattresses usually will have extra comfort layers or quilted cover to provide more comfort.
- Back sleepers should opt for less thickness and medium-firm mattress to get proper support. A memory foam layer thickness of around 3 to 5 cm is sufficient for this type of sleepers.
- Stomach sleepers: A firm mattress is essential for such sleepers to reduce strain on the lower back and also to maintain a neutral spine. A thickness of 5 to 7 cm is ideal for stomach sleepers.
- Side sleepers: There is more pressure on the shoulders and hips hence thick mattress with extra cushioning helps in alleviating tension from pressure points. A layer over 7cm is ideal for them.
Choose the mattress thickness wisely when you buy as that can affect your sleep and in-turn your health.
