Your Sleep is Critical

Finding the perfect mattress can make a dramatic difference, not only in your sleep but all aspects of your daily life. Getting quality sleep can improve your productivity, prevent muscle and joint pain as well as ultimately leading to improved happiness as many studies show a direct correlation between hours slept and your happiness. Due to the importance of getting a good night's rest, we recommend making your sleep a real priority in your life and ensuring you have the right tools and knowledge to take control of your sleep. Finding the right mattress for side sleeping comes down to mattress firmness, types of materials, your own weight, budget and personal preference.

Ideal Side Sleeping

Before we dive into mattress recommendations it's important to talk through what goes into ideal side sleeping and what your main goals should be with your posture. Side sleeping is very popular but it's a position that can require a lot of fine-tuning to get right.

  • Keep your spine straight and level with the mattress surface - this ensures your spine is in a natural and neutral position free of twisting or flexing that cause stress muscles and joints over extended periods of time.
  • Pay attention to your pillow height - Commonly side sleepers are using a pillow that is too thin, causing a bend in their neck, and sometimes a pulling effect on your spine and cause back and shoulder problems
  • Make sure your lower back is supported - A common complaint of light-weight side sleepers or people sleeping on a firm mattress where you're not getting support due to poor contouring ability of the mattress.
  • Keep your hips vertical and free of twisting or rocking - keeping your hips vertical with the high side directly above the lower side ensures as minimal stress on your lower back.

Mattress Firmness For Side Sleeping

Side sleeping is a very common sleeping position and one, that when done correctly can yield quality sleep with the right pillow, mattress, and sleep posture. Here's what to look for in a mattress as a side sleeper. Firmness is the biggest factor the finding the right mattress for side sleeping. Firmness needs are dependent on your weight, shape and personal preference. Typically side sleeping requires a medium to medium-soft mattress to properly support your body, especially your midsection and lower back. If you are heavier than average you're likely to need a firmer mattress and if you're lighter than average you may want to go softer than average. This balance can be hard to get right. The image below shows how a mattress that is too soft can allow your spine to curve downward. While increasing the firmness too much can also create issues as it doesn't give enough on your shoulders and hips and prevents you from finding that ideal neutral position.

Mattress Material for Side Sleeping

The next biggest decision is choosing the material or construction of your mattress. There are more options now than ever before so this can be somewhat daunting. Traditional mattresses sold by mattress retail stores are typically innerspring/coil mattresses. Memory foam has become very popular in the last decade, as well as Latex. Traditional innerspring mattresses are also still popular and there are a number of hybrid mattresses that combine the benefits of different materials. Generally, most affordable mattresses fall into these categories:

Construction Pros Cons Ideal Sleep Postion
Memory Foam Cost, Noise, Minimal motion transfer, good support for a
variety of people and positions, excellent contouring
Can sleep hot, Off-gasing/VOCs, Initial Smell Side Sleeping
Latex Natural material, sleeps cool Cost, Motion transfer not as good as memory foam, Not as supportive/on the firm side Back/stomach sleeping
Innerspring Sleep cooler depending on the type of outer layer Firmer/contours less to your body than memory foam, often requires a box spring, expensive to ship, motion transfer, noise Back/stomach sleeping

We've found that memory foam mattresses tend to be better for side sleepers due to the unmatched contouring ability of the material.

Side Sleeping Tips

While your mattress is critical to getting good sleep there are other aspects to your sleep that you should be conscious of as a side sleeper

  • Make sure you're practicing ideal side sleeping - Ideal side sleeping is all about keeping your spine in a straight line parallel with your bed and making sure it is fully supported, especially in your midsection and lower back.
  • Avoid twisting or rotating your hips - This adds extra tension to your spine and can cause back pain fairly quickly. Adding a pillow between your knees can help significantly with this.
  • If you're petite or skinny pay careful attention to midsection just above your hip - It's common for this area to lack support as a side sleeper. If you're experiencing pain in this area try rolling a small towel to create a cervical roll and place it in this area.
  • Make sure your pillow is the right thickness - Pillow thickness is very important to side sleeping because it determines how your spine in your neck is aligned with the rest of your body(more so than other positions). Generally you want a thicker pillow as a side sleeper. If you like your pillow but concerned about it's thickness you can fold a towel to raise it up.

FAQs

What's the sleep best position for digestion?

Many resources online claim stomach sleeping has digestive benefits but there are limited studies on the topic. There is however fairly extensive research on the relationship between sleep health and gastrointestinal health like this study published in the BMC Gastrointestinal. There is also data emerging on the digestive benefits associated with side sleeping on your left side. The best advice is to make sure you're getting great quality, recuperative sleep and worry less about what type of position you sleep in.

What are healthy sleep positions?

While it is possible to get a good night's rest in any sleeping position, side and especially back sleeping offer many benefits compared to stomach sleeping. When you sleep on your side and back, it is much easier to maintain a neutral spinal alignment where your spine, muscles, and joints are relatively stress-free.

How do I reduce shoulder pain with side sleeping?

Side sleeping does tend to compress your shoulder and amplify pain in the area. One of the best ways to reduce this is to sleep on the opposite side. You may also want to make sure your pillow isn't too thin. A thin pillow can increase the pressure on your shoulder. A properly sized pillow will distribute your weight more evenly between your head, neck, and shoulders.
