Are you conflicted in choosing a bonded foam mattress or memory foam bedding?

If yes, it is probably because both these foams are extremely beneficial, and they also serve different purposes. Even though memory foam is the most common foam type, several mattresses have been introduced having the rebonded foam.

Hence, before you make a buying decision, we think it would be of great help if you study both these materials in-depth.

What Is Bonded Foam?

A bonded foam is made by fusing scrap foam and the hardened to provide the material with its required density. That’s why the bonded foam is the heaviest material amongst all other foam types. 

Benefits Of Bonded Foam

  1. Has higher durability for a better purpose
  2. Won’t sag or get depressed early 
  3. It will provide huge support to your spine’s structure and alignment 
  4. Helps you to sleep in any manner

What Is Memory Foam?

Memory foam is manufactured from polyurethane material, and it will change its surface structure based on the application of heat and pressure. However, once these forces are removed, they will return to their original position. 

Benefits Of Memory Foam

  1. It will provide the maximum support to your backbone and the muscles 
  2. Helps in relieving the tension from the muscle fibres
  3. Offers the ultimate form of comfort, thanks to the high conforming rate
  4. Can keep the top surface cool with the gel-based molecules 

Similarities and Differences: Bonded Foam Vs Memory Foam 

FeaturesBonded foamMemory foam
Feel, Support & ComfortSupport Comfort
Temperature RegulationNoYes 
Motion IsolationNo Yes
FirmnessHigh Medium
Hypoallergenic Yes Yes
OdourNo No
Lifespan High Low 
  • Feel, Support & Comfort: Memory foam has a softer feel, so it is added as a comfort layer in the mattresses. On the other hand, the bonded foam is hard and used for support. 
  • Temperature Regulation: Memory foam can control the temperature of the mattress’s surface in two ways. Firstly, it maintains a standard level of air circulation which further dissipate the heat. However, the memory foam is infused with cooling gel technology to keep the surface temperature always cold.

    In addition, bonded foam is quite dense, and hence no air can pass through it. 
  • Motion Isolation: Memory foam can easily resist the transfer of motion, so you will be able to sleep comfortably. Even if your partner is moving now and then, your sleep won’t be disturbed.

    As for the rebonded foam, it has no part to play in regulating the motion transfer.
  • Firmness: Memory foam has a varying firmness, ranging between 5 to 6.5 based on the construction method, its firmness, and the inclusion of gel-based molecules.

    On the other hand, the rebonded foam has a firmness between 6 and 8 which is why it forms the best support material.  
  • Hypoallergenic: Memory foam has hypoallergenic properties, which will help you to sleep comfortably on the bed. Even if you suffer from any skin problem, you won’t have to worry about worsening conditions since the foam won’t cause an adverse reaction.

    Similarly, the bonded foam is usually placed at the third or fourth level, making it far away from the top. With no direct contact, you won’t have to worry about your skin’s health. 
  • Odour: One of the best things about memory and bonded foams is that they won’t emit any unpleasant smell. Memory foam is made from high-quality PU material, which is processed in the factories multiple times. Furthermore, it allows air circulation to a certain extent so that you won’t receive any odour.

    As for the bonded foam, it will place it at a far distance from the top. Hence, with no direct contact, the scents won’t reach your nose. 
  • Lifespan: Bonded foam can last for a long time, thanks to its unique construction. As multiple scrap pieces of different polyurethane foams are mixed and hardened, ten folds increase its density. That’s why it can easily last for more than five to seven years.

    On the other hand, memory foams usually last for five years maximum. This is much softer and, hence, can sag earlier than the bonded foam. Moreover, once the fibres in the memory foam start disintegrating, it becomes softer, increasing the depression rate. 

Strength And Weakness Of Bonded Foam

Strength 

  • Has high density, which has reduced the sagging rate
  • Provides excellent support to the backbone and muscles
  • Also helps in support the spine and maintaining its alignment in different postures 

Weakness

  • Heavyweight and hard to move
  • It can easily form cracks and tears

Strength And Weakness Of Memory Foam

Strength 

  • Helps in reducing the body pain 
  • It can be integrated with cool gel technology for temperature regulation
  • Prevents the transfer of motion 

Weakness

  • Can sag earlier than expected on the application of too much force 
  • Doesn’t always allow air to pass through 

Which Is Better: Bonded Foam Or Memory Foam?

Bonded foam and memory foam are used for different purposes. Memory foam is mainly meant to provide comfort, while on the other hand, the bonded foam is meant to provide support.

So, comparing these two materials won’t lead to a fruitful decision. Moreover, there are a few mattresses where memory foam has been added as the comfort material while the bonded foam has been used in the support layer. So, based on purpose and the related aspects, we cannot exactly compare these two materials.

FAQs

Bonded foam has high durability, which is why it will last for a long time. However, as the foam is stiff and highly dense, you need to handle the mattress with care to prevent any tear or crack in the foam. Also, you should follow the manufacturer’s instructions to ensure that the bonded foam can last for at least five years. 

The bonded memory foam does consist of scrap memory foam pieces also. Moreover, the density of this mattress material is quite high, which will provide the optimal support to your spine and reduce the pain to a great extent. 

There is no particular time for replacing the memory foam mattress, as it completely depends on whether your mattress has sagged beyond the limit or not. It also depends on the condition of the memory foam and its performance. For example, suppose your mattress’s memory foam fails to conform or provide support to your backbone. In that case, you should think about getting the product replaced at the earliest. Sleeping on such bedding for a prolonged time will cause more harm than good.

Under normal conditions, the memory foam won’t hurt your back too much. Memory foam is the best material that can reduce back pain, release the pressure from the tangled knots in the muscles, and support the alignment properly. However, with years, the material will start losing its integrity. Once the layer is worn out sag, sleeping on the mattress will cause back pain. 

Memory foam is mainly characterized by its ability to conform to the top surface in response to the application heat and pressure. Once the forces are taken away, the foam regains its original shape. However, when the foam has worn out, you can observe that the foam will either take too much time to retain its original shape or won’t come back to the shape at all.
