Eli & Elm: Unique Design for Side Sleepers
Our research shows that the Side Sleeper Pillow is designed for the unique needs of individuals who tend to sleep on their sides. The shape of the pillow, along with the adjustable shredded fill material, allows side sleepers to customize the pillow to suit their comfort preferences.
U-Shaped for Support
Side sleepers need head and neck support to maintain alignment. The Eli & Elm Side Sleeper Pillow is U-shaped to cradle the head and neck, preventing over-extension of the neck.
Choice of Shredded Fill
The pillow is available with your choice of fill material. The shredded latex noodle and polyester fiber fill offer responsive support and can be adjusted to suit your firmness and thickness preferences. The shredded memory foam and polyester fiber fill contours to your neck and shoulders and has a softer feel than the shredded latex.
Removable Cover
The cover fabric is a blend of cotton, spandex, and polyester. It unzips to allow you to add or remove filling for a firmer or softer pillow. The Side Sleeper Pillow also has an all-polyester liner. For additional softness, you can also buy the shredded latex or memory foam pillow together with a 100% cotton pillowcase.
OEKO-TEX and CertiPUR-US® Certified
The materials in Eli & Elm’s Side Sleeper Pillow must meet safety certification standards. The shredded latex pillow is OEKO-TEX® certified, and the memory foam option is CertiPUR-US® certified. Both certifications ensure that the materials in the pillow are free of a wide range of harmful substances and are low in VOCs (Volatile Organic Compounds).
Size and Dimensions
Available in queen size only, the pillow measures 17″ W x 27″ L. The loft or thickness is adjustable. A single queen-size pillow offers plenty of room and can fit one at a time on a smaller-size bed. Of course, queen and king-size beds can accommodate multiple queen-size pillows.
Eli & Elm Side Sleeper Pillow: Benefits and Any Disadvantages
The Side Sleeper Pillow is designed with the needs of side sleepers in mind. We have researched the materials and construction of the pillow, and we now share our thoughts on what it’s like to sleep on.
Head and Neck Support for Side Sleepers
Side sleepers tend to need a pillow that provides extra support for the neck and shoulders, along with a high loft. The U-shaped Eli & Elm Side Sleeper Pillow has a unique design that provides support in the key neck and shoulder areas. Poor neck and shoulder alignment can throw the spine out of alignment and result in morning aches and stiffness. For proper alignment, the goal is to keep the neck at a neutral angle and prevent flexing. The shape of the Side Sleeper Pillow cradles your neck at a neutral angle, so you can rest comfortably.
Adjustable Shredded Fill
The best side sleeper pillow thickness and firmness is ultimately a matter of personal preference. That’s why we think you’ll like being able to remove or add fill material to the Eli & Elm Side Sleeper Pillow. Whether you choose the shredded latex noodle or the shredded memory foam option, you can have a pillow that’s just right for your neck and shoulders. Adjust the responsive latex fill to lower the pillow loft and firmness level. Change the memory foam fill to enjoy the right amount of cloud-like comfort for you.
Temperature Regulation
With its breathable fill material, the Side Sleeper Pillow allows airflow to draw heat away from the pillow. The shredded memory foam fill won’t trap body heat as it conforms to your shape and cushions your neck and shoulders. The natural latex itself is a cooling, breathable material, further enhancing the pillow’s cooling properties when you choose the shredded latex option.

When you’re spending hours every night resting your head on a pillow, it’s good to know that the pillow is safer for you and the planet. Fortunately, the Side Sleeper Pillow is certified free of harmful substances. The shredded latex pillow is OEKO-TEX® certified and the shredded memory foam pillow is CertiPUR-US® certified, ensuring that the pillows are free of several harmful chemicals and low in VOC emissions.
Hypoallergenic
This Eli & Elm pillow is made with dust-resistant and mite-resistant materials. Do allergy sniffles keep you awake at night? If so, you may want to add this pillow to your search for a leading side sleeper pillow. However, if you are allergic to latex, talk to your health care provider before opting for the shredded latex fill.
Washable Cover
We think you’ll appreciate how easy it is to keep this pillow clean. The cotton-blend cover is removable and machine washable in cool water. It can even go into the dryer on the low setting. The fill material is not washable, but you can keep the pillow feeling fresh and clean with regular cleaning.
