Best Mattress Topper for Side Sleepers – Buyer’s Guide

If you’re a natural side sleeper, then it’s a really good idea to invest in a mattress topper that has been specially designed to provide your body with the support it needs whilst you’re sleeping. This will prevent any strain on sensitive pressure points, such as your shoulders or hips, whilst simultaneously ensuring that your spine is kept aligned. 

However, when you’re looking at which mattress topper is best for you, there are a few things you need to consider before making your purchase. We’ve put together a list of points to give some thought to when you’re shopping around, which will help you find one that will provide you with the right support for side-sleeping and ensure that you’re kept as comfortable as possible all night long.

Bed Size

First and foremost, you need to make sure that the mattress topper you’re looking at is going to actually fit on your existing mattress. Many mattress toppers come in a wide range of sizes that vary from Twin to California King, and finding the correct size for your bed will ensure it fits properly and that it performs as well as it promises to.

It’s worth noting that, much like with clothing, the size of a mattress topper can range from brand to brand as well, and that a King Size in one brand may not be exactly the same as a King Size from another. With that in mind, we’d recommend grabbing a tape measure and writing down the dimensions of your mattress so you can cross reference them with the mattress topper you’re considering purchasing. 

Doing this will ensure that you get the correct size the first time around, and prevent the hassle of having to return it for another. 


Once you’ve figured out what size you need, it’s time to look at the different materials that are used in the construction of mattress toppers, and how each one can help you with your side sleeping preference.

The most common material you’ll see used in mattress toppers for side sleepers is memory foam. This is a fantastic choice to go for, as it is able to mold itself to the natural contours of your body and give you the feeling of sinking into your mattress, whilst ensuring that your entire body is supported and kept in a position that won’t result in any aches or pains. 

There is one downside to memory foam, however, that is reported time and time again – it has a newly-manufactured smell that can take a few days to dissipate. However, if you can get past this and have the patience to wait it out, then there’s no doubt that you’ll be getting an amazing night’s sleep with a memory foam mattress topper.

If you’re not so keen on the idea of a memory foam mattress topper, then there are also natural alternatives available. One of these is ultra plush down, which uses an over-filling technique to produce an extra thick mattress topper that will provide support and comfort for side sleepers without any memory foam being incorporated into the construction.

Natural latex is another excellent alternative to memory foam, and it works much in the same way by molding itself to the contours of your body and providing support for your hips, shoulders and back throughout the night. Natural latex is also highly durable, so it will be able to handle a great amount of tossing and turning without showing any signs of wear. 

And, of course, there are mattress toppers that are made up of a combination of different materials. This usually involves a bottom layer that is constructed using memory foam, and a top layer that is made from a cushioning material such as down or quilted fibers. These mattress toppers give you the best of both worlds, and can often provide additional comfort and support that single-material options may not be able to. 


It’s also important to give some thought to the thickness of your mattress topper as well, as the difference between these can have a massive impact on how well it will support you if you tend to sleep on your side. 

These thickness can vary as much as 1” – 4”, which can make finding the perfect level for your individual needs a little confusing. So, to help make things clearer, we’ve summarized each thickness below.

  • 1” Mattress Toppers: This level of thickness will add a very subtle change to your existing mattress, and will provide you with a fair amount of support without adding a dramatic height to your bed
  • 2” Mattress Toppers: These will make a big difference to the feel of your bed, and will basically remove the feeling of your existing mattress, yet are not so thick as to take away any support that it offers. 
  • 3” Mattress Toppers: A 3” topper will dramatically change the feeling of your bed altogether, and will provide a huge amount of extra support for your spine and for the pressure points that are often affected by side sleeping.  This size is often the most popular choice for side sleepers.
  • 4” Mattress Toppers: A mattress topper of this thickness is essentially like putting another mattress on top of your existing mattress. Your back, shoulders and hips will be fully supported throughout the night, however it will add a lot more height to your bed, which isn’t ideal for some people.


You also need to think about how breathable your proposed mattress topper is as well, as this will have a huge impact on how comfortable you are throughout the night. 

Memory foam mattress toppers are often infused with a cooling gel, which means that it will help to keep your body temperature at a consistent level throughout the night and prevent you from overheating.

Natural latex is also very good at regulating your body temperature, and has naturally-occurring air chambers that allows air to circulate up through the mattress topper which doesn’t only prevent you from overheating but also allows your skin to breathe throughout the night. 


Just like your duvet and pillows, you’ll need to give your mattress topper a wash from time to time to keep it looking and smelling fresh, and to generally keep it in good condition so that it lasts longer.

Some mattress toppers require a trip to the dry cleaners in order to give them a wash, and although this means that you don’t have to worry about making sure you’re cleaning it correctly, can create an inconvenience in your schedule as you’ll need to find the time to make the trip for drop off and collection.

Luckily, however, there are many mattress toppers available that can simply be placed in a washing machine and cleaned at home. Some can even be tumble dried to speed up the drying process, or simply to give them a little plump up as and when required. 

A clever cleaning feature that some mattress toppers also have is a baffle box design. This works by using pockets of stitching to keep the interior down or quilted fiber in place, and prevents it from shifting or piling into one corner when it’s being washed. 

Purchasing a mattress topper that can be cleaned at home will also save you a lot of money in the long run and will certainly prevent you from paying a hefty dry cleaning bill. However, it’s really important that you read the care instructions and wash it as directed, otherwise you could cause irreversible damage. 


Finally, it’s a really good idea to look at what kind of warranty your mattress topper includes. These can range from 30 days right up to 10 years, and finding one that will cover you for a replacement over a long period of time will help to give you peace of mind when purchasing, as well as confidence in knowing that you’re buying a quality product.

Some mattress toppers also come with a money back guarantee or a trial period, and these are also good to look out for if you’re uncertain about whether you’ve made the right choice.
