When you want to buy a mattress, do you often see ads for memory foam mattresses and gel memory foam mattresses? You may be wondering, what is the difference between a memory foam mattress and a gel memory foam mattress? Which one should I choose? First, let’s analyze what memory foam mattresses and gel memory foam mattresses are.
What is memory foam?
Memory foam, also known as slow-rebound foam, is a type of foam with a density between 33D-80D. It was developed by NASA's Ames Research Center in 1966 to reduce the enormous pressure on astronauts' bodies when they leave the ground. It is also used in seats and safety belts. Memory foam contains open-structured molecules that can move under the influence of external forces. These molecules help disperse the force to fit the entire contact surface.
What is memory foam made of?
Memory foam is usually made from a high-density foam called polyurethane. Polyurethane is a synthetic material created by chemically reacting polyols and diisocyanates. What's special about memory foam is that its structure is sensitive to both temperature and pressure. It adjusts to the body's shape and temperature accordingly. Afterward, it slowly returns to its original form, offering comfortable support and pressure relief.
What are the characteristics of memory foam?
Memory foam refers to the material that has the ability to slowly deform. After external force deforms it, it will slowly return to its original shape. The mattress has both viscosity and elasticity. It absorbs impact energy and can be used for a long time without significant deformation.
What are the pros and cons of memory foam mattresses?
Pros:
-
Pressure relief: Memory foam evenly distributes the weight of the body and relieves pressure points on the shoulders, back, and hips. This makes it ideal for side sleepers and those with joint pain.
-
Spinal support: Memory foam adjusts to the curves of the body, maintaining the natural alignment of the spine. This helps improve sleeping posture and reduces back pain.
-
Motion isolation: Memory foam has good motion isolation properties. If one party turns over at night, the other party will not be affected, making it suitable for people who sleep with a partner.
-
Hypoallergenic: Most memory foam mattresses have hypoallergenic properties. These properties prevent the growth of dust mites, mold, and bacteria. As a result, they are suitable for people prone to allergies.
-
Long-lasting: Memory foam lasts a long time and doesn’t easily deform or collapse. It provides lasting comfort and support.
-
Ergonomic: Memory foam can adapt to different parts of the body, providing balanced support and comfort. It also helps relieve physical fatigue.
Cons:
-
Temperature sensitivity: The softness and firmness can change significantly with temperature. It tends to keep heat in the summer and become firmer in colder weather.
What is gel memory foam?
Gel is a substance with temperature-regulating properties that lies between a liquid and a solid. It can efficiently absorb body heat into the interior of the gel mattress, achieving a cooling effect. Gel memory foam adds gel particles to memory foam, combining the benefits of both memory foam and gel.
What is gel memory foam made of?
Gel memory foam is made from traditional memory foam combined with a gel material. Memory foam itself is a polyurethane foam that can adjust its shape according to changes in body temperature and pressure. Gel is typically created by injecting tiny gel particles or incorporating layers of gel into memory foam. The gel's main function is to help regulate temperature. It reduces heat buildup in a memory foam mattress by absorbing and dispersing body heat, thus improving sleep comfort.
What are the characteristics of gel memory foam?
It has significant heat dissipation properties, making it suitable for summer or for people prone to sweating. It combines the contouring support of memory foam with the cooling properties of gel. This helps to disperse body heat and provides a cooler sleep experience. It also maintains better structural stability, reducing deformation after long-term use.
What are the pros and cons of gel memory foam?
Pros:
-
Cooling effect: The addition of gel helps dissipate heat and keep the mattress cooler. This makes it suitable for people who sweat easily or are temperature-sensitive.
-
Comfortable support: Like traditional memory foam, it adjusts to the body’s curves and relieves pressure points. This makes it especially beneficial for side sleepers or those with back pain.
-
Better durability: Gel memory foam is generally more durable than ordinary memory foam. It maintains a longer lifespan and resists sagging.
-
Reduced motion disturbance: It absorbs motion well. This minimizes disturbances from a partner turning over or moving at night.
Cons:
-
Higher price: Gel memory foam typically costs more than traditional memory foam mattresses.
-
Initial odor: There may be a slight chemical odor (volatile organic compounds, VOCs), but this will dissipate over time.
-
Variable cooling effect: While gel provides some cooling, it may not completely cut overheating. This is especially true for those who are extremely heat-sensitive.
-
Heavier weight: Gel memory foam mattresses tend to be heavier than regular mattresses, making them less convenient to move.
The difference between memory foam and gel memory foam
Gel memory foam has better temperature-regulating properties than regular memory foam. It is more expensive, but provides a cooler sleep experience. Memory foam rebounds more slowly compared to gel memory foam.
Q: How long dose a memory foam mattress last?
A: The lifespan of a memory foam mattress typically ranges from 7 to 10 years, depending on frequency of use, quality, and maintenance. High-quality memory foam mattresses are generally more durable.
Q: Will the smell of memory foam mattresses disappear?
A: New memory foam mattresses often have a slight odor from "volatile organic compounds" (VOCs) released. The smell will gradually dissipate within a few days to a week. It's recommended to let the mattress air out in a well-ventilated area.
Q: What sleeping positions are suitable for memory foam mattresses?
A: Memory foam mattresses are suitable for various sleeping positions, especially for side and back sleepers. It relieves pressure on your shoulders and hips and helps keep your spine aligned.
Q: Will memory foam mattresses overheat?
A: Memory foam mattresses may keep heat. But there have been many improvements, such as gel memory foam with added gel particles that help regulate temperature better.
Q: Do memory foam mattresses need to be flipped?
A: Most memory foam mattresses do not must flipping as they are usually designed with a layered structure. They are intended for single-sided use. But, rotating the mattress regularly can help extend its lifespan.
Q: Are memory foam mattresses allergy-friendly?
A: Memory foam mattresses are generally friendly to people with allergies because they are resistant to dust mites and hypoallergenic. This makes them less likely to accumulate allergens.
Q: Can memory foam mattresses support heavier people?
A: Yes, high-density memory foam mattresses can support heavier weights. But, heavier individuals should opt for mattresses with greater thickness and density to ensure enough support and durability.
Q: Can memory foam mattresses be used with adjustable bed?
A: Most memory foam mattresses can be used with adjustable bed. They are flexible enough to bend according to different angles of the frame.
Q: Are gel memory foam mattresses cooler than memory foam?
A: Yes, gel memory foam mattresses tend to be cooler than memory foam. The gel has heat-absorbing properties that help dissipate heat. This improves the mattress's temperature regulation.
Q: How long does a gel memory foam mattress typically last?
A: Like memory foam, the lifespan of a gel memory foam mattress typically ranges from 7 to 10 years, depending on quality, frequency of use, and care.
