Bonded Foam Mattress

Bonded Foams

The bonded foam mattress is a jam of mattresses that gives you a softness to sleep. It is made from a mixture of latex and polyurethane foam with a cotton or microfiber cover. They are commonly used by many people with chronic diseases such as arthritis, but they have been found to be beneficial for everyone who sleeps on it.

Bonded foam mattress also has airflow through the mattress, which allows the body to not overheat during sleep. The latex in the mattress helps relieve pain caused by arthritis because it absorbs heat and then distributes it evenly.

Another main characteristic of bonded foam mattresses is that they are often quite durable because there are no springs that will sag or break over time as traditional mattresses contain. Many people find that their bonded foam mattress is more economical than a traditional mattress because they will not have to buy a new one when the old one is worn.

They are also affordable for people who want a softer bed. Bonded foam mattresses can be purchased in different firmnesses.

They can be purchased with or without CertiPUR-US certification with no formaldehyde, low VOCs, and heavy metals laced inside the foam.


Pros of Bonded Foam Mattress:

  1. They are made of natural, organic materials such as cotton and latex.
  2. They are not toxic.
  3. They are durable.
  4. They have a higher resiliency than traditional mattresses, which can be helpful to those with arthritis, back problems, and other conditions that require firmness. It is to help support the body during sleep without causing more pain during movement in the morning.
  5. They cause less pressure on joints and bones when in use because of their airflow through the mattress, which allows for no overheating of the body while sleeping.


Cons of Bonded Foam Mattress:

  1. The price is higher because of the increased resiliency, making it more durable than traditional mattresses.
  2. It can be complicated to clean if the material is soiled with sweat and or fluid.


PU Foam Mattress

PU Foam Mattress

Polyurethane foam is a relatively new development in the mattress industry, but it has grown substantially in popularity over the past 20 years.

The use of polyurethane foam was first introduced to consumer markets as a brand of “sports mattresses” for people who enjoy sleeping on air mattresses at sporting events.

However, the supply of this limited-edition, high-quality mattresses seemed to dry up after only a few years when their manufacturer discontinued them due to economic concerns.

These PU foams are mainly used for sleeping soundly.

After a few years, the use of polyurethane foam has become more widespread in home furnishings and other consumer products. Polyurethane foam’s outstanding durability and pressure-compression properties make it ideal for furniture, building materials, electronics, plastics, shoes, and other products.

These mattresses contain polyurethane foam. Polyurethane foam is also known as polyether ketone or PEEK. The plastic-like smell-less common among other “organic” foams is a clear giveaway.

Polyurethane foams are made from C 4 hydrocarbons (polyols). In addition, certain polyurethane foams hold their shape better than rubber mattresses while still giving the same amount of cushioning as other foam mattresses.


Pros of PU Foam Mattress:

  1. They have sound motion isolation.
  2. They have good stability.
  3. They are great for sleeping hot people, as they breathe well, thereby dissipating heat away from the body and dissipating less heat than other materials.


Cons of PU Foam Mattress:

  1. They may not provide enough contouring, especially for side sleepers who need extra support in their hips, which is what lower-density foams are known for.
  2. They are more expensive than polyfoam mattresses and have the typical issues associated with polyurethane foams.
  3. They are not easy to flip or rotate compared to other materials and require more care.
