Sleeping on your side is the most popular sleep position, with more people falling asleep comfortably in this position than any other. Despite the popularity of side sleeping, people who sleep this way always seem to have difficulty finding a comfortable and supportive mattress. 

Today, we’re going to take a closer look at some of the best cooling mattresses for side sleepers and share some essential factors to consider so you can select the perfect bed and enjoy a restful night’s sleep tonight. 

How to Select a Mattress: Side Sleeper Edition 

Regardless of the type of mattress, you’re looking for, every side sleeper should know some essential things. Here’s what you’ll want to consider before you select your new mattress. 

Mattress Types

Over the years, many different types of mattresses have come and gone. While you’ll find the occasional outlier that doesn’t fit one of these categories, virtually all of today’s best mattresses are either innerspring, memory foam, or a hybrid of the two. 

Innerspring mattresses are one of the oldest styles, and they feature hundreds of coils inside the bed that are designed to support you as you sleep. These mattresses are typically comfortable and offer the best airflow of any mattress, making them an excellent choice for people who sleep hot. But, they tend to be noisy, and they transfer motion more than other styles.

Foam mattresses have skyrocketed in popularity over the past decade or so for many reasons. Foam offers great contouring and support, and it’s excellent at relieving pressure points. The most popular types of foams are memory foam and latex. These mattresses are typically made of one or more bass layers topped with one or more memory layers or latex foam. 

But, foam is solid, and it doesn’t provide nearly the amount of airflow as a coil mattress. These mattresses tend to sleep hotter than innerspring mattresses. Many companies employ cooling technologies to help their memory foam mattresses retain less heat. 

Hybrid mattresses are the final popular mattress type, and they marry the best aspects of innerspring and memory foam mattresses. These mattresses feature one or more memory foam comfort layers on top of coils. The result is a mattress that sleeps cooler than a full memory foam mattress without as much noise or motion transfer as a coil mattress. 

Important Factors to Consider

The mattress style and the firmness you select are both matters of personal preference, and you’ll need to decide which is most comfortable for you. But, there are some characteristics you’ll want to look for regardless of the style or firmness level that’s most comfortable for you. 

Trial Period 

Most mattress companies offer generous trial periods so you can bring the mattress into your home and decide if you like it after sleeping on it for some time. Some companies provide lengthy trial periods of up to a year. You should have no trouble deciding if a mattress is for you or not within the first few months, so make sure the manufacturer offers you a 90-day or more extended trial. 

Warranty

A warranty is the best way to protect yourself if your mattress is defective. Today’s top manufacturers offer warranty periods of 10 or more years. Considering the average lifespan of a mattress is 15 years or less, you’ll want to select a bed that offers a warranty that will cover the mattress’s useful lifespan.

Frequently Asked Questions

When it comes time to shop for a new mattress, these are the most common questions that side sleepers have about the process. 

What kind of mattress is best for side sleepers? 

Support and contouring are the most critical aspects to consider as a side sleeper shopping for a new mattress. When you sleep on your side, you create pressure points at your shoulders and hips, and it’s crucial to find a bed that adequately addresses these areas. 

You’ll find excellent foam, spring, and hybrid mattresses for side sleepers, so the kind of mattress isn’t as important as your personal comfort is. For support and pressure point relief, many people prefer memory foam or hybrid mattress, but you should try all three styles before deciding on which is best for you. 

What mattress firmness is best for side sleepers?

Firmness is mostly a matter of personal preference, and the support and contouring a mattress offer are the most important criteria to consider. As a rule of thumb, side sleepers tend to prefer a mattress in the medium to the medium-firm range. 

Keep in mind that your body type and weight will significantly impact what feels most comfortable to you. A 250-pound man will probably find that a firm mattress offers excellent support and contouring, while someone half that weight might find the same mattress to be incredibly hard and uncomfortable. 

If you’re unsure, start by trying some medium and medium-firm mattresses. Be sure to also lay down on softer and firmer mattresses to narrow down which feel you like best.

Is memory foam better for side sleepers? 

No material is necessarily better or worse for people who sleep on their side. Your mattress preference is a personal decision, and what’s comfortable for one side sleeper may be uncomfortable for the next. 

With that said, most tend to agree that memory foam provides superior pressure relief and contouring than other mattress materials do. Relieving pressure points is crucial for a good night’s sleep, so you’ll undoubtedly want to consider a memory foam mattress if you’re a side sleeper.
