How to Shop for a Mattress as a Side Sleeper

Finding the perfect mattress as a side sleeper doesn’t have to be overwhelming. Since comfort varies from person to person, it’s crucial to consider your unique needs, including your body weight and ideal firmness level. If you share your bed, account for your partner’s preferences as well. Before purchasing, evaluate the following factors to ensure the mattress meets your needs:

  • Motion Isolation

    A mattress with great motion isolation absorbs movement on one side of the bed and prevents it from transferring to the other.

  • Temperature Neutrality

    This performance category refers to how well a mattress maintains a comfortable temperature.

  • Pressure Relief

    A mattress can either reduce or worsen pressure build up in areas like the hips and shoulders due to uneven spinal alignment and lack of support.

  • Edge Support

    Stability along the edges and the rate at which the compression recovers after weight is removed allows for greater ease getting in and out of bed.

  • Ease of Movement

    A mattress with a responsive, springy surface is usually easier to move across than one that sinks beneath your weight.

  • Odor Emissions

    Most new mattresses emit chemical odors after unboxing, but some smell stronger or take longer to dissipate than others.

FAQ's

What is the best mattress for a side sleeper?

The best mattress for a side sleeper will vary by individual preferences, but most side sleepers prefer a softer mattress than back sleepers as their shoulders and hips need more cushioning. Many side sleepers like all-foam options for extra cushioning. We’ve put together a list of some of our favorite choices here.

What type of mattress does a side sleeper need?

Side sleepers generally need a mattress that:

  • Conforms to the body: To cushion pressure points on the hips and shoulders.
  • Provides medium to medium-soft firmness: This allows enough give to align the spine while maintaining support.
  • Offers zoned support: Some mattresses provide targeted support for different body areas, which can be beneficial.

What is the best mattress topper for a side sleeper?

A mattress topper for side sleepers should add plushness and alleviate pressure points. In most cases, you’ll want to look for a topper that adds softness. Look for a topper that is marked as “medium-soft” or “soft”. The best options include:

  • Memory Foam Toppers: Provide excellent contouring and cushioning.
  • Down or Down Alternative Toppers: Add softness but may lack support.
  • Gel-Infused Toppers: Help regulate temperature for hot sleepers.

How firm should a mattress be for a side sleeper?

A mattress for side sleepers should be softer than a mattress for other types of sleepers, as side sleepers sink in more in the shoulders and hips. Look for a mattress that is medium-firm to medium-soft. This firmness level provides enough cushion to the hips and shoulders while maintaining proper spinal alignment. Of course, firmness preference is subjective, so if you know you prefer a firmer bed, go for a medium-firm choice.

Which side is better to sleep on?

Sleeping on your left side is generally considered better for overall health. It promotes better digestion, reduces acid reflux, and improves blood circulation. However, sleeping on the right side may be preferable for some people, such as those with certain heart conditions. Ultimately, the best side depends on individual comfort and health needs.

Does side sleeping hurt the hip joint?

Side sleeping can sometimes cause hip discomfort, especially if the mattress is too firm or lacks proper support. Pressure on the hip joint from an inadequate mattress or sleeping position can lead to pain. Using a mattress designed for side sleepers or placing a pillow between your knees can help align your hips and reduce strain.
