The Best Flat Pillow For Side Sleepers Who Don’t Like Big Fluffy Pillows

Read our review of the best flat pillow for side sleepers.

If you are in a hurry and just want to know what the best flat pillow for side sleepers is, I recommend the Avocado Molded Organic Latex Pillow.

Due to the space between the head and neck when side sleeping, the best pillow for a side sleeper should support the neck and cushion the head. 

Thicker pillows usually serve the purpose but they shouldn’t be so thick that they misalign the spine.

Too thin pillows on the other hand might not offer the much-needed support.

If you, however, feel uncomfortable using thick pillows, there are several flat pillows that can help you sleep without having to worry about stiff neck or shoulder pain.

Here is a review to narrow down the best flat pillow for side sleeping.

Today I am reviewing the following best pillow for people who like sleeping on their side:

Things to consider when looking for the best flat pillow if you are a side sleeper

What kind of pillow should a side sleeper use?

The best pillows for side sleepers should support and cushion the head and neck to prevent pressure build-up. Memory foam, latex, feather, down, down alternative, and buckwheat pillows are among the best.

What size pillow is best for side sleepers?

Common sizes for side sleeper pillows include standard, queen, and king. The size of the pillow you need is determined more by your sleeping habits than your sleeping position. 

A side sleeper who rarely moves in their sleep can use the standard size while those who move a lot or spread out more on the pillow surface will require the larger queen and king sizes.

There’s also the rare body pillow for side sleepers looking for extra support and comfort for the entire body. This can range in dimensions depending on the size of your body.

What pillow density is best for side sleepers?

Side sleepers need medium-density pillows with medium to high loft to avoid misalignment of the spine caused by too much sinking or too much elevation of the head and neck.

What firmness is best for side sleepers?

A pillow that is medium-firm to firm provides a good balance between support and comfort. It ensures that a side sleeper does not sink enough to misalign the spine or get so elevated that they experience discomfort around the neck and shoulders.

Is memory foam good for side sleepers?

Memory foam pillows possess great contouring abilities and feel softer when they come into contact with body heat. With the right firmness, side sleepers can get both pressure relief and support.
