Best Mattress Topper for Side Sleepers

Updated July 16, 2019

If you are a side sleeper, you know how hard it is to find the right mattress for you. Covering all the pressure points seems almost impossible all the time so you end up tossing and turning throughout the night, trying to settle down in the best possible position to sleep in. And you wake up feeling horrible. This is where mattress toppers come into the picture because they can turn your uncomfortable bed into a feathery but supportive cloud. There are so many high-quality mattress toppers out there such as Best Price 4” Memory Foam topper, and finding the right one will be super easy.

Things to Look for When Buying a Mattress Topper For Side Sleeping

Side sleepers do have more needs than back sleepers so the process of choosing the best mattress topper for you will take some extra time. You have to go over each and every product thoroughly in order to find out as much as possible about your potential future mattress topper. So, what are some of the main features you should look for?

Examine Your Mattress

If your mattress is old and dented, a topper will not be able to mend it completely. Indentations might be the reason why you can’t find the right sleeping position because they can add extra pressure to your body. So, before considering a topper, consider if you need a brand new mattress. But if your bed seems to be in good condition without any damage to the surface or the internal structure, a mattress topper will work just fine.


Different sleeping styles require different thickness. For instance, stomach sleepers will feel super comfortable on a very thin mattress topper while side sleepers will not depending on the firmness level of your mattress. This should be your first clue in determining the actual size of your future mattress topper.

I suggest that you choose a thicker mattress topper because it will cover all the pressure points easily and form around the contours of your body, keeping the spine as aligned as possible. Three or four inches will work just fine for side sleepers. Larger mattress toppers are usually quite dense as well.

Heat Retention

Heat retention is probably the only issue users do have with memory foam toppers. If you live in a warm climate and you purchase a cheaper mattress topper without proper ventilation, you will feel stuffy and hot throughout the night, making your rest time super stressful. So, it will not matter if you are a side sleeper or not – you will not get enough sleep whatsoever.

Luckily, manufacturers did find a way to deal with this issue and they generally improved the air flow within a mattress as well as ventilation. This means that the topper itself will release the heat quicker and easier, enhancing the airflow underneath the covers and regulating your body temperature.

On the other hand, there are always gel infused mattress toppers which distribute the body heat evenly over the surface, making you feel super comfortable. They do not have the actual cooling effect, but can be useful when the temperatures outside are on the rise.


Memory foam mattress toppers are not waterproof and they cannot be cleaned in a washing machine. This will damage the structure and make it completely unusable in the future. With that said, you can spot clean the topper if needed. Just make sure you use a dry cloth afterwards in order to collect the moisture.

You can also make your memory foam mattress topper completely water repellent by using a waterproof cover. It is an excellent way to ensure that your topper will not be stained by accident and it is particularly useful for parents who have small children.

The Infamous Odor

Even if you never purchased a memory foam topper (or a mattress) before, you are probably familiar with the well-known odor that emerges once you unwrap the product and you lay it on the flow in order to let it set itself up. It is a strong smell that is very specific for this type of product. Yes, it is very chemically and unpleasant for more delicate noses, but some users will still remain unbothered by it.

The good thing about this odor is that it will go away in a couple of days if the mattress topper is made of high quality materials. If not, the smell will stay and you will definitely notice it while sleeping in your bed. It might not be as strong after some time, but it will linger.

And the bad thing is that you have to wait for a couple of days in order to try your new topper out. You simply have to give it enough time to vent out the chemicals and form itself in the right shape so you can enjoy it to the maximum.

If you want to avoid the permanent odor, check for any certificates that prove the quality of the product and provide you with the list of materials which were used in the process of making the said mattress topper. Finding the country of origin is also quite useful because some toppers are imported and they are not required to pass the same quality tests.
