Best Mattress for Side Sleepers

November 18, 2021 | Casper Editorial Team

If you’re a side sleeper, you’re not alone. An estimated 74% of Americans assume the same position when they hit the sack, making side sleeping the most common sleeping position

But getting a good night’s sleep on your side means you need a mattress that’s, well, on your side. That means a mattress that’s able to accommodate the various points of pressure relief you put on it, responding with the exact combination of give and resistance in the places you need them. Not all mattresses are equally suited to this task, so let’s take a look at the best type of mattresses for side sleepers.

Made with the perfect balance of support and comfort, our selection of mattresses provide side sleepers with exactly what they need for a good night’s sleep.

Which Type of Mattress is Best for Side Sleepers?

As a side sleeper, you already know that the sleep position is a cozy and comfortable way to cycle through your nightly REMs. But you might be unaware that side sleeping has also been known to have a few major health benefits, like: 

  • Aiding in digestion 
  • Reducing back pain 
  • Alleviating sleep apnea symptoms

That said, being a side sleeper doesn’t always mean you’re sleeping on a bed of roses. Despite its benefits, side sleeping can also pose a few undesirable outcomes, like neck and shoulder pain depending on the mattress type. 

So what’s the best mattress for side sleepers? Ultimately, the best type of mattress is one that can support the side of your body comfortably—particularly your hips and shoulders, where the most pressure is placed. 

At Casper, we do this by designing mattresses that utilize gel pods to foster continuous ergonomic support and contribute to your ideal level of firmness.

How Firm Should a Mattress Be for Side Sleepers?

For side sleepers, mattress firmness can be a big issue. Most side sleepers will find that, like Goldilocks, they prefer a mattress that’s neither too hard nor too soft. A happy medium is a medium firm mattress.

A mattress that’s too firm can mean you’ll have too much resistance in those places where your body needs a little more give, like the hips and shoulders, which can cause pain in those areas.

On the other hand, a mattress with too little firmness can mean your body won’t get the proper support in those areas where you really need it, like your neck and lower back for spinal alignment.

Key Considerations for Side Sleepers

For side sleepers, a medium-soft to medium-firm mattress is the way to go. But how do you know if your mattress is too firm, or not firm enough? 

Here are some things to keep in mind:

  • Spinal alignment – The heavier parts of your body, like your hips and shoulders, should sink into the firmer mattress slightly, ensuring that your spine maintains a neutral alignment. This is essential to have in a mattress 
  • Manufacturer’s rating – Most mattress manufacturers use a standard 1-10 scale for rating mattress firmness, with 1 being the least firm and 10 being the most. Side sleepers will be most comfortable on a mattress that’s rated at either a 5 (medium-soft) or a 6 (medium-firm).
