Best Side Sleeper Mattress

Side sleepers are people who spend their nights sleeping on the side, it’s obvious, but why is this important? What happens to our bodies when we sleep on the side?

First of all, our spine is in a different position when compared to sleeping straight on our back – people who sleep on their backs don’t engage the manifold of muscles in the lower back, and their spine offers more support. That’s not the case with side sleepers.
People who sleep on the side can enjoy their sleep more if they sleep on a good mattress. The hips and spine will relax or strain, depending on the quality of the mattress, which can lead to a good night’s sleep or serious back and hip issues.
The sole purpose of this article is to bring the attention of side sleepers, as everyone deserves a good rest. We’ll help you find a good mattress, and explain all the benefits of each model separately.

Benefits of picking the right mattress for sleeping on your side

The benefits of picking a good mattress are huge – not only will the quality of your sleep improve, you’ll also gain a significant boost to the health of your joints. People who suffer from chronic back and joint pain will clearly spot the difference between good and bad mattresses, but that’s not always easy.
For instance, most shops offer a chance to try their products out. You may think at the time that the mattress you’re trying out is good, but there’s a chance that’s not the case in real life. First of all, you won’t be as tired as when you’re about to go to sleep – every mattress will seem fine until you’ve slept in it for several nights.
This is why reputable brands offer a complete refund if you’re not satisfied. The models we’re about to review are not only good – you can return them if they don’t please you. Let’s see what the benefits of good mattresses are:

Relieving pressure on your joints

Even if you do nothing all day, your joints are active. In fact, even if you sit around and watch TV, there’s a certain amount of pressure on your joints. When you sleep, your body is supposed to relax and lose the tension. Bad mattresses, however, are not capable of fulfilling this task.
A good mattress will be comfortable on your joints – you’ll wake up fresh in the morning, and the pressure you used to feel will be gone. How is that so? The real difference between a good and bad mattress is that the former are capable of molding to your joints while the latter are not.

Keeping spine aligned

People who sleep on the side often have more problems with their spine. When you sleep straight, your back is straight, and, of course, your spine is straight too. Side sleepers, on the other hand, usually shift their spine in unnatural position if they are not sleeping on a mattress that’s good for them.

Best & Worst Types of Mattresses for sleeping on your side

If we’re to discuss what the best types of mattresses for side sleepers are, we should talk about the qualities a mattress must have. These qualities are as following:

• Firmness

The first quality is firmness. A firm mattress is usually good for straight sleepers, but the situation is quite different when it comes to side sleepers. Namely, people who sleep on the side need a moderately firm mattress – a mattress that’s too soft might not provide decent support while those mattresses that are too tight are often the cause of back pain.
A firm mattress won’t be able to contour to your curves while a soft mattress will make your body sink in, leaving you without any support whatsoever.
On a scale of 1 to 10, 1 being the softest mattress you’ve ever slept on, and 10 being the firmest mattress you’ve ever slept on, you want to get a mattress with a firmness rating of 5. The golden middle won’t be too firm on your back or too soft for decent support.

• Support

Basically, a mattress that’s able to support your body and weight without any problems is the best mattress for side sleepers. While supporting, your mattress will dispense the pressure output on your body equally, alleviating most of the pain from your joints, hips, and back.
Now, as firmness and support are two different things, you’ll want a special mattress that’s able to contour to your body. Remember, a mattress with good supportive capabilities will contour to your shape and alleviate most of the pain.
• Comfort rating
The comfort rating quality is self-explanatory, but let’s be more specific on the matter. First of all, a single mattress can be comfortable to some while uncomfortable to others. So, if we’re to find a universal comfort rating, we’re going to have to take several factors into account.
The two main factors are firmness and support which we’ve already talked about, and the third (most important) factor is the subjective preference. You are the judge of whether or not a mattress is comfortable to you as you will be sleeping on it. Take some of the other factors into consideration, but always remember that you have to like it personally – even if the definitions we gave you are not in favor of that specific mattress.
