BETU Cooling Pillow Review: A Top Contender for Side Sleepers
The BETU Cooling Pillow offers side sleepers customizable loft and a cool-to-the-touch surface, though the cooling effect may diminish over time.
Pros & Cons
Pros
- Adjustable loft is perfect for dialing in the right height for side sleeping and arm positioning.
- Shredded memory foam provides conforming support that many users find relieves neck and shoulder pressure.
- Cool-to-the-touch cover provides initial relief for hot sleepers.
- CertiPUR-US certified foam and machine-washable cover offer good value and ease of care.
- Set of four provides excellent value for the price.
Cons
- The cooling effect is reported by some users to fade after a few weeks of use.
- The 'soft' firmness rating may not be enough for those seeking an extra firm pillow for side sleepers.

- Not specifically designed as a hybrid side back sleeper pillow, though it can work for multiple positions.
Our Verdict
The BETU Cooling Pillow is a strong, value-oriented option for side sleepers, particularly those who sleep with an arm under the pillow. Its key advantage is the adjustable shredded memory foam fill, which allows users to customize the loft and firmness to create the perfect gap for shoulder and arm positioning. While its initial cooling sensation is praised, feedback suggests this effect may not be permanent. For side sleepers prioritizing customizable support over absolute cooling longevity, this pillow is a compelling choice.
Who Should Buy This?
This pillow is specifically engineered for comfort-seekers who need adaptable support. It excels for side sleepers, including those who tuck an arm under the pillow, as the adjustable fill lets you build the necessary height to keep your spine aligned. It's also a solid pick as a best pillow for side and back sleepers who shift positions, and for hot sleepers looking for initial cooling relief. The ability to customize firmness makes it a versatile memory foam side sleeper pillow.
Buy It If:
- Side sleepers who need to customize loft for proper shoulder and arm alignment.
- Combination sleepers (side/back) who need a pillow that adapts to different positions.
- Hot sleepers seeking a pillow with a cool-to-the-touch surface.
- Shoppers looking for a high-value set of pillows for a guest room or whole bed.
Skip It If:
- Strict stomach sleepers who need a very low-profile, flat pillow.
- Anyone seeking a guaranteed, long-lasting best cooling pillow for side sleepers.
- Those who prefer a pre-set, extra firm pillow and don't want to adjust fill.
- Shoppers looking for a dedicated body pillow for side sleepers or leg pillows for side sleepers.
Performance & Features
Based on aggregated customer feedback, the BETU pillow performs well in core areas of support and comfort for side sleeping, with some caveats regarding its cooling claims.
What Works Well
Users consistently praise the pillow's support and pain relief. One reviewer noted it "helps with pain relief—I wake up without the usual neck and shoulder stiffness." The adjustable fill is repeatedly highlighted as a major strength, allowing side sleepers to add or remove foam to achieve the ideal height, which is crucial when sleeping with an arm under the pillow. The initial feel is described as "ice cold and silky soft," providing welcome relief for warm nights.
What Could Be Better
The primary weakness noted is the durability of the cooling feature. Several reviews indicate the cooling effect "didn't last" or "fades quickly," with one user stating it felt like a regular pillow after about two weeks. While adjustable, achieving a truly firm pillow for side sleeper preferences might require adding all the fill, and some users desire more inherent firmness from the foam itself.
Build Quality & Design
The pillow uses CertiPUR-US certified shredded gel memory foam, which promotes airflow better than solid blocks. The double-sided cover features a standard soft fabric on one side and a cooling ice silky fabric on the other. This construction aims to serve as both a supportive memory foam side sleeper pillow and a best cooling pillow for side sleepers, though real-world results on the latter are mixed.
The queen size dimensions (20" x 28") are standard. The magic is in the adjustable loft. Side sleepers, particularly those with broader shoulders or who sleep with an arm under the pillow, will likely need to add most or all of the fill to create sufficient height for proper spinal alignment, transforming it from a soft pillow to a more supportive one.
Care is straightforward: the outer cover is machine washable. The shredded foam fill is durable and should maintain its resilience, though, as noted, the cooling properties of the cover may lessen over time. The foam is housed in an inner zippered bag for easy adjustment.
Value for Money
At roughly $16 per pillow in a four-pack, the value is exceptional. You get the benefits of adjustable shredded memory foam—a feature often found in more expensive single pillows—at a budget-friendly price point. For side sleepers experimenting to find their perfect loft, this adjustability alone offers significant value, even if the cooling aspect is not permanent.
