As we enter a new decade, few things remain the same for things like our sleep needs. Incorrect! Many believe that humans have evolved, but sleep patterns and needs have largely not changed.

As our lifestyle changes, it affects our basic needs. According to the latest report, there will be a growing demand for memory foam and latex mattresses. Strong growth is expected for 2020-2025. Latex, which is expensive, adapts to niche markets. Memory foam mattresses will be significantly incentivized to meet this demand.

What is Memory Foam? What is it made of?

Memory Foam is a type of polymer, first designed by NASA in the mid-1960s for the use of seats and seat belts. It was known to have cushioning and pressure-relieving properties, which is why it became popular later in 1990.

It uses body heat to mold to our body shape and is known for providing remarkable support and comfort.

Memory foam is made from a polymer called polyurethane. Polyurethane is known for its binding properties. Polyurethane made with chemicals gives contour and support to our bodies. It is also called viscoelastic, which is a combination of two concepts: viscosity and elasticity.

Viscosity is related to slow movement when pressure is applied. Elasticity tells us to what extent the material regains its shape when the pressure is released.

The combination of the two gives you the feeling of a memory foam that contours to the body and gives us the feeling of a fluffy cloud without losing the quality of the support.

Why has the Memory Foam been so successful?

The US online mattress market has been booming over the past 5 years. It is valued at over $30 billion and is expected to grow rapidly in the coming years.

When NASA decided to make memory foam technology publicly available in the 1980s, little did they know it would destroy the mattress industry.

Before the introduction, the market was mainly occupied by spring mattresses. When foam was introduced, it clearly had great advantages over traditional beds.

The foam is soft and gives you a plush feeling. It does not bend easily and has minimal movement transfer. It turned out to be a huge advantage, especially between couples.

The only major drawback is that it retains body heat and makes you feel warmer in bed. This led to innovations and gel memory foam was introduced.

The popularity of memory foam continued to increase.

Although, to make it cheaper, many companies use calcium carbonate and other chemicals. Counterfeiting in the manufacture of memory foam is rarely discussed on public platforms.

Weight of Memory Foam Mattress

The weight of a memory foam mattress basically depends on the size and density of the mattress. As the density of the foam increases, the weight increases.

The concept of density can be confusing for many mattress buyers. In simple terms, density is a weight of 30 x 30 cubic cm or one cubic foot.

Therefore, a dense mattress has a weight of about 5.0 pounds, while a medium and less dense mattress falls under this range.

We should always aim for a mattress of at least 4 pounds. This thick mattress is durable and lasts longer. If you’re buying a queen size or higher, I’d opt for a denser mattress so it doesn’t sink too deep into the foam and make movement difficult.

Lightweight people, on the other hand, opt for a lightweight mattress that gives them a soft, cushioned feel. They don’t need a lot of body weight distribution and will like the feel at the top.

Different Types of Memory Foam Mattress

  1. Traditional Memory Foam–  Traditional Memory Foam is the original classic polyurethane foam, a petroleum-based polymer that was introduced in the 1980s. It provides good contouring and shaping of the body. One of the main drawbacks of traditional memory foam is heat retention, which makes the sleeping surface warm. To curb this problem, further improvements were made to memory foam.
  2. Open-cell memory foam–With a unique internal structure, this foam has open cells to allow air to flow easily through the mattress. Inner pockets formulate airflow and are made with the basic idea of ​​keeping sleepers cool. But this can make the mattress less dense because quality is at stake. However, newly produced open cell mattresses have overcome this drawback.
  3. Gel-infused Memory Foam mattress: To solve the problem of heat retention, gel infused memory foam mattresses have been developed.

A gel-infused memory foam mattress can be of two different types:

  • They are usually made of a heat-absorbing gel. Keeps the surface cool and prevents heat retention. It gives you a refreshing feeling.
  • Another is phase change material that helps modulate body temperature. It absorbs and releases heat to help the body maintain normal temperature conditions.

These mattresses not only have a layer of gel, but also copper or gel beads to aid in cooling. Some give an additional egg carton structure to formulate airflow in the mattress. They also have an added fragrance to remove gel or copper odor.

      4. Plant-based memory foam mattress– Many companies have the petroleum-derived components in                 traditional memory foam mattresses, but they are now being replaced with plant extracts by a few to form               another category. Some of these contain coconut, soy and other materials that help the mattress bounce                   better. The recovery time of these mattresses is better than most memory foam mattresses. They also have                a cleaner carbon footprint.

Pros and Cons of Memory Foam Mattress


  • It is highly permeable which aids in the alignment of the spine of the body.
  • It is shaped according to the shape and structure of the body and thus provides a better contour.
  • The memory foam function helps the mattress return to its original shape after removing the force.
  • Helps relieve pressure and is good for allergies.
  • It is very durable for all types of sleepers and requires minimal maintenance.
  • Memory foam mattress offers a good motion isolation function and is thus a couple-friendly mattress.


  • The dense nature of memory foam mattresses increases the overall weight of the mattress, making it a bit difficult to move.
  • It has a certain initial odor that can cause irritation in some people.
  • Most mattresses tend to trap heat, so they can make a person uncomfortable while sleeping.
  • Memory foam mattresses are not waterproof and absorb the liquid to deep levels, making it more difficult to clean the memory foam mattress.
  • It takes time to adjust to firmness and sleeping position with frequent movements during the night.
  • Buying a memory foam mattress with minimal flaws puts a lot of strain on our pockets because they are expensive.

Characteristics of Memory Foam

  • Hypoallergenic-  This feature of memory foam makes it perfect for allergy sufferers as the components used usually do not cause allergies. Due to the dense structure, there is not much room for the accumulation of mold, mildew and dust mites. Occasional vacuuming and spraying baking soda while cleaning will provide long-lasting protection for the mattress against allergens.
  • Pain Relief- Memory foam is a good choice for those suffering from arthritis or joint pain. Helps relieve pressure point pain. Eliminating the use of feathers helps to better contour the body. Memory foam provides the ideal firmness for most sleepers.
  • Pressure Point Relief – This is one of the most important features to look for online when buying a mattress. Memory foam provides good pressure point relief in the heaviest or densest part of the body in any sleeping position. Suppose you sleep on your side, rocking your shoulder and hips. It allows the mattress to absorb the pressure exerted by the body. Its viscoelastic property surpasses other mattresses in this property.
  • Spinal Alignment and Support-  Sleeping on the wrong surface tends to affect our back support. While some wake up stiff in the morning, others may develop chronic back pain problems. Memory foam mattresses use some of our body heat to form a bed in the shape of our sleeping position. The foam allows the body heat to soften and molds to the posture. This feature helps maintain our body and create better support for the spine. The curve formed in the foam also promotes support for the wood.
  • Good for All Sleeping Position-Memory Foam Mattress supports all types of sleepers. Provides firmness for side sleepers, provides lumbar support for back sleepers and a cushioned feel for stomach sleepers. It also excites combination sleepers who tend to change positions frequently during the night. For them, the foam of the mattress takes shape with every change. Certainly, no one has to compromise on the sleeping style of their mattress.
  • Motion Isolation-  Memory foam is known for its motion isolation. It absorbs the pressure and vibration caused by one person’s movement so that the other person sharing the same bed does not wake up from sleep. This property makes it an ideal option for couples and light sleepers.
  • Ideal for Adjustable Beds-  Memory foam is a perfect option for adjustable beds as they are easily compressible. Its bending property does not break the foam. They are flexible enough to be molded into any shape without compromising their lifespan.
  • Durable- -The most outstanding feature of memory foam is its durability, despite all the features it offers. Because they can be restored to their original shape together with a high density, they have a longer shelf life and do not sag over time.
