Are you tired of having sleepless nights due to the constant twisting and turning of your partner? 

If yes, then it’s time to think whether your mattress can resist the motion transfer or not. It can prevent motion transfer in memory foam or pocket spring mattresses with ease. Hence, you will be able to sleep better without having to wake up in the middle of the night due to your partner’s movement. 

Since most of you might not have a clear idea about what motion isolation is or the factors which determine this feature, we have presented here a complete guide to help you out in this matter. 

What is motion isolation in a mattress? 

Motion isolation is a special feature in a mattress that will restrict the flow of compressive forces in a radial direction. As a result, you won’t have to face any problem sleeping peacefully, regardless of how many twists and turns your partner is making. 

What causes motion transfer in the mattress? 

As you lay over the mattress, the weight of your body gets distributed evenly throughout the surface. Now, when you turn or twist, the centre of gravity of your body will shift to another point which will cause the flow of motion to different areas of the mattress. As a result, any person sleeping beside you will be able to feel the change in the mattress surface structure. This is the main cause of motion transfer in a mattress. 

Why is motion isolation required to consider while buying a mattress? 

Often people ask about the reasons for which motion isolation feature is important to have in a mattress. If you are in the same dilemma, these pointers will help you understand the importance of this particular feature. 

  1. Motion isolation will help you in sleeping properly. When your sleep partner moves from one place to other, the mattress will be compressed. But, these forces won’t radiate out, which will prevent you from feeling the movements. 
  2. It will enhance, thanks to this feature, the durability of the mattress with ease. It can reduce the mattress’s sagging rate since it will radiate no force out to the surrounding space. 
  3. With motion isolation, the mattress won’t make a single noise. Hence, your sleep won’t be disturbed, which is why most sleepers prefer to have mattresses having motion isolation features. 

Which type of mattress can provide motion isolation?

There are several types of mattresses in the market. However, not all of them can provide motion isolation features. Only two materials, pocket spring and memory foam. However, the pocket spring layer should have higher coil numbers, and the memory foam should be thick with high responsiveness. 

How does memory foam enhance motion isolation? 

A thicker memory foam mattress will help in more conforming. So, when you press the surface, only the portion coming in contact with the compressive forces will change its shape accordingly. As a result, the forces won’t be transferred to other parts of the memory foam, preventing the transfer of motion from one point to another. 

How does the pocket springs provide motion isolation? 

In the pocket spring mattresses, the spring coils aren’t connected. Instead, they are insulated within a pocket-like cylindrical structure. That’s why when you press the mattress surface, only those coils will depress on which the pressure is applied. Also, the extent of compression will depend on the value of point force. That’s the reason pocket springs are the best when it comes to motion isolation in a mattress. 

On what factors does the motion isolation depend? 

The motion isolation feature of a mattress depends on several factors that will help you determine whether the chosen mattress is appropriate for you. These determinants are: 

  1. Mattress typeDepending on the type of mattress you are buying, the level of the motion isolation feature will depend. For example, both memory foam and pocket spring can reduce the motion flow. However, the pocket spring is more efficient in comparison to the memory foam. 
  2. Mattress thickness: In most cases, the motion isolation is directly proportional to the thickness of the chosen mattress. If the product has a height of around 6” to 8”, the inner layers will resist the motion flow. However, when you are considering a thinner mattress, you will be able to feel the motion of another sleeper, even if it’s a slight movement.
  3. Firmness: Softer mattresses with a firmness value ranging from 3 to 5 cannot resist the motion transfer. However, mattresses having higher firmness values like 5 to 8 can easily provide the best motion isolation capacity. 

Conclusion

Now, you have a decent idea about what the motion isolation feature is and why it is important for your health and the mattress. All you have to do now is choose a proper mattress having an enhanced motion isolation feature so that you won’t have any difficulty sleeping. Then, you can check out the reviews for your chosen mattress to know about this particular feature and the efficiency of preventing the transfer of the motion. 

FAQs

No, fortunately enough, the motion isolation feature in a mattress won’t cause you any harm. Rather, it will help reduce disturbances during sleep, improve durability, and decrease the mattress sagging rate. 

If your existing mattress does not come with a special isolation feature, you can use a memory foam mattress pad or topper, which will reduce the motion disturbances to a great extent. 

Yes, the motion isolation feature is perfectly safe for your kid. Therefore, you won’t have to worry about any health problems in your child. Hence, if you want to buy such a mattress, you should go for it.
