What Does The Density Of A Memory Foam Mattress Mean?
What Is Memory Foam?
Developed in the mid-1960s for NASA aircraft seats, memory foam is made from a compound called viscoelastic. It is both extremely energy absorbent and soft.
Memory foam molds to the body in action to heat and pressure, uniformly distributing body weight. It then goes back to its original shape as soon as you eliminate the pressure.
In addition to safeguarding versus impact, these properties make memory foam extremely comfortable. After its “virgin flight” for NASA, memory foam made a venture into other applications. For example, it was used as cushioning in helmets and shoes. Medicine found a use for it in prosthetics and products to prevent pressure ulcers such as seating pads for people who are badly handicapped.
Then, memory foam truly took off. It’s now popular for its use in pillows, mattress pads, and mattresses, which can be found in various densities and depths.
What Are the Benefits of Memory Foam?
Could the unique homes of memory foam boost your sleep? Sleep specialist Donna L. Arand, PhD, states that unbiased studies supporting the declared benefits of memory foam– or the effects of any specific type of sleeping surface area– are lacking.
This is true for a variety of factors, she states. This kind of sleep research study can be pricey, if carried out separately. Or it is “chased” by a shadow of predisposition, if supported by market.
Some sleep innovation, such as memory foam, is reasonably brand-new, so it hasn’t been well studied. But possibly among the harder stumbling blocks to testing the health advantages of mattresses such as memory foam is the subjective nature of sleep. It is just hard to measure.
What Are the Disadvantages of Memory Foam?
Gromer says that memory foam products may retain temperature, which might make them less comfy in warm weather condition. Arand has not heard this complaint from her patients. “In our culture, the majority of people can adjust their thermostats or blankets for the proper season,” Arand states.
When brand-new, memory foam can produce an odd chemical odor– a phenomenon called offgassing. To minimize this problem, the Sleep Products Safety Council, a sleep products trade group, advises airing out the bed mattress or pad for at least 24 hr before putting sheets on it. “If you follow directions, the smell dissipates quickly,” Arand states, “However I have actually never ever heard of anyone having responses to it.”
Are Memory Foam Products Safe for Young Children?
” I would highly recommend preventing this and comparable really soft products for use in infants’ beds,” Gromer says. “That’s due to the fact that soft bed linen traps [co2] and increases the threat of sudden infant death syndrome (SIDS) deaths.” Pagination
To combat the heat of the conventional variety, open cell foam was created to help individuals remain cool. The interior structure has pockets that permit airflow. On the plus side, sleepers will not get so hot, but the holes imply that the surface area of the bed is less dense. It’s frequently a lower quality product that will not last as long.
Memory foam is understood for helping with discomfort. It’s a leading choice among people with arthritis and people who have fibromyalgia due to the fact that it finest simulates the feeling of sleeping on a fluffy cloud. The contouring likewise assists to keep the body in a natural alignment, which we’ll get to in a moment.
If you’re the kind of individual who has a hard time to get comfy on a standard bed mattress, or you have a difficult time finding an ideal firmness level, then you’ll probably appreciate this product.
Pressure Point Relief
Pressure point relief has ended up being something of a buzzword in recent years, but for excellent factor. And this is where viscoelastic beds shine.
Consider it by doing this: what happens when you rest on your side on a slab of concrete? You’ll probably feel the ground digging into your hips, your arm will fall asleep within minutes, but you’ll be lying there, wide-awake, questioning why you’re resting out in the street.
Due to the fact that viscoelastic shapes to your curves, it takes the pressure off your denser and much heavier body parts like the hips and shoulders. This discovery was what offered this material its start in health centers. Not only did it assist patients sleep more conveniently, however it also worked to prevent things like bedsores.
Back Support & Spine Positioning
When you rest, your spinal column should preserve a comparable position as when you’re standing. When people sleep on the incorrect surface area, their spinal column tends to jut out or collapse in at unnatural angles. If you get up aching or stiff in the early morning, it could be your mattress’s fault. With memory foam, the contouring results permit the spine to keep its natural shape.
The best method to test your bed to see if it allows for correct alignment is to rest in your corner and have someone take a picture of you from behind. If you ‘d prefer to work alone, then set a timer on your smart device’s camera and take a photo that way.
Take an appearance at the angle of your spine. It must be a nearly perfectly horizontal line. If your hips and shoulders are raised up or sinking down, then you understand it’s time for a different bed.
Individuals looking into this type of bed mattress should make certain they get one that has the proper density. If it’s too firm or soft, you’ll miss out on the benefit of proper spinal alignment. As a general rule, the higher the foam density, the firmer the mattress. All mattress business and website will specify what the density specifications are. Look for something that’s at least 3.5, if not closer to 5.0.
