Slumber Cloud UltraCool Pillow Review: A Cool-Touch Pillow for Hot Sleepers
The Slumber Cloud UltraCool Pillow uses NASA-developed fabric for a cool feel, but its true temperature regulation and softness may not suit everyone.
Pros & Cons
Pros
- Cool-to-the-touch Outlast fabric cover feels refreshing initially.
- Soft, adjustable down-alternative fill is easy to fluff and shape.
- Hypoallergenic and Oeko-Tex certified, free from harmful chemicals.
- Machine washable for easy care.
- Made in the USA with quality construction.
Cons
- Cooling effect is inconsistent and doesn't last all night for many users.
- Soft/medium firmness lacks the support needed for strict side sleepers.
- Pillow's slick cover can cause standard pillowcases to slide off.
- At $114, it's a premium price for mixed cooling performance.
- Not the best firm pillow; may be too soft for those needing orthopedic support.
Our Verdict
The Slumber Cloud UltraCool Pillow is a solid, well-made option for those prioritizing a cool initial feel and a soft, adjustable loft. Its premium Outlast fabric provides a noticeable cool touch, and it's easy to care for. However, its cooling performance is inconsistent according to user reviews, and its soft-to-medium firmness may not offer enough support for side sleepers or those with neck and shoulder pain. While not the best pillow for side sleepers or the best back sleeper pillow for everyone, it's a decent choice for combo sleepers who appreciate a plush feel.
Who Should Buy This?
This pillow is best for back and combination sleepers who sleep warm and value a soft, plush feel. It's a contender for those seeking the best pillow for side and back sleepers who prefer a softer profile. It may also appeal to hot sleepers looking for a best cooling pillow for side sleepers, though its softness means it's not ideal for strict side sleeping. Those with significant neck pain should look for a more supportive orthopedic memory foam pillow.
Buy It If:
- Back sleepers who want a soft, cool-touch pillow.
- Combination sleepers who shift positions.
- Hot sleepers who appreciate a cool initial sensation.
- Buyers wanting hypoallergenic, easy-care bedding.
- Those interested in NASA-inspired temperature-regulating technology.
Skip It If:
- Strict side sleepers needing firm, high-loft support (not the best pillow for side sleepers).
- People who need all-night, active cooling technology.
- Anyone seeking a firm pillow for neck alignment.
- Those on a tight budget; it's a premium-priced pillow.
- Sleepers who use standard pillowcases (due to slick cover).
Performance & Features
Based on aggregated customer experiences, the Slumber Cloud UltraCool Pillow excels in initial comfort and ease of adjustment but shows variability in its core cooling promise.
What Works Well
Users consistently praise the pillow's soft, 'cloud-like' comfort and how easily it can be fluffed to a desired shape. The Outlast fabric cover is widely noted for its immediately cool feel upon contact, which many find refreshing. As one side sleeper reported, they 'sleep comfortably' with it. The hypoallergenic build and machine-washability are also significant practical strengths.
What Could Be Better
The primary weakness is the inconsistent cooling performance. Multiple reviews state the pillow 'heats up fast' and is 'not really a cooling pillow,' with one user noting it's 'not cooling for post menopause' as the soft fill allows the head to sink in and trap heat. The soft firmness, while comfortable for some, lacks the supportive structure needed for proper spinal alignment, especially for side sleepers, making it less ideal as a pillow for side sleepers with support needs. The slick cover is a minor but frequent nuisance.
Build Quality & Design
The pillow features a down-alternative polyester fill encased in a proprietary Outlast® fabric, a phase-change material originally developed for NASA. This fabric is designed to absorb, store, and release heat to regulate temperature. The entire pillow is Oeko-Tex Standard 100 certified, ensuring it's free from harmful substances. While not a memory foam side sleeper pillow, the down-alternative fill provides a traditional, malleable feel.
With a 5.5-inch loft and soft/medium firmness, this pillow offers a lower-profile, cradling fit. It suits back sleepers well but may not provide adequate lift for side sleepers, potentially leading to misalignment. The fill is adjustable, allowing sleepers to redistribute it for a slightly customized fit, but it doesn't offer the precise adjustability of an adjustable bed pillow with removable inserts.
Care is straightforward: the entire pillow is machine washable, a major advantage over many premium pillows. This promotes hygiene and longevity. The materials are high-quality and the construction appears durable, though long-term performance of the cooling coating with repeated washing is not detailed in available reviews.
Value for Money
At $114, the Slumber Cloud UltraCool Pillow sits at a premium price point. You are paying for the proprietary Outlast technology and US manufacturing. The value depends heavily on how much you benefit from the cooling feature. For those who find it effectively regulates temperature, it's worth the investment. For those who don't experience lasting cooling, it becomes a pricey, albeit comfortable, standard pillow. It's not the best value for someone seeking the best pillows for neck and shoulder pain, as more targeted supportive options exist at similar or lower prices.
