ToggleWISHSMILE Cooling Shredded Memory Foam Pillow Review: A Top Pick for Side and Back Sleepers
With its adjustable shredded foam design and cooling cover, the WISHSMILE pillow is a strong contender among the best pillows for back sleepers and side sleepers who want customizable support.
Pros & Cons
Pros
- Excellent adjustable loft and firmness via zippered fill removal
- Effective cooling cover that stays cool-to-the-touch
- Breathable, shredded foam construction prevents heat buildup
- High initial fluffiness and support noted by many users
- Great value as a 2-pack for the price
- Machine-washable cover for easy care
Cons
- Firmness may degrade over time for some users, according to a few reviews
- Initial 'new foam' smell requires airing out (common with memory foam)
- May be too thick for some stomach sleepers even after removing fill
- Adjustability requires manual effort; not a quick-adjust system
Our Verdict
The WISHSMILE Cooling Shredded Memory Foam Pillow delivers impressive value, offering the key feature many sleepers seek: customizable loft and firmness. Its cooling cover and breathable, open-cell foam construction effectively address heat retention, a common complaint with solid foam. For side sleepers needing a firm pillow and back sleepers seeking medium support, the adjustability is a major win. While it may not provide the rigid, unchanging support of a solid orthopedic memory foam pillow, its moldable comfort and temperature regulation make it a versatile and highly recommended option for most combination sleepers.

Who Should Buy This?
This pillow is specifically engineered for sleepers who switch positions. It shines as a pillow for back sleepers and side sleepers, with manufacturer guidance to remove about 1/4 of the fill for a medium loft ideal for back sleeping, and to use it as-is for the firmer support needed by side sleepers. It's also a strong candidate for the best cooling pillow for side sleepers who often experience pressure point heat. Those seeking a firm pillow for side sleepers will appreciate the out-of-box density, while back sleepers can easily tailor it to a lower profile.
Buy It If:
- Combination sleepers (side/back) who need one pillow for multiple positions
- Hot sleepers seeking a cool-to-the-touch surface and breathable foam
- Those wanting a customizable 'Goldilocks' firmness level
- Shoppers looking for good value in a 2-pack set
- Individuals seeking a best pillow for side sleepers with neck and shoulder pain due to its contouring support
Skip It If:
- Strict stomach sleepers who need an ultra-low, flat profile
- Anyone wanting a solid, non-adjustable orthopedic memory foam pillow for rigid support
- People sensitive to off-gassing odors who can't air out a pillow for 24-48 hours
- Those who prefer a traditional down or polyester fill that's instantly fluffy without expansion time
Performance & Features
Based on aggregated customer feedback and product specifications, the WISHSMILE pillow performs well in core areas critical for spinal alignment and comfort, particularly for combination sleepers.

What Works Well
The standout feature is customizable support. Multiple reviewers praised the ability to add or remove filling to achieve their perfect loft, making it a versatile pillow for side and back sleepers. The cooling performance is consistently highlighted, with users noting the cover genuinely feels cool and the shredded foam promotes airflow, preventing the 'heat trap' of solid foam. Initial support and fluffiness receive high marks, with many describing it as both supportive and cloud-like.
What Could Be Better
A minor weakness noted by a few long-term users is that the firmness may not be permanent; one reviewer mentioned it caused neck pain after a year as it lost its supportive structure. The need for a break-in period (airing out) is a minor inconvenience. While adjustable, finding the perfect fill amount requires trial and error.
Build Quality & Design
The pillow uses shredded, open-cell memory foam encased in a zippered cover made from Cooling Rayon with Japanese 'Cool-to-Touch' technology on one side. The shredded foam design is key: it's more breathable and moldable than a solid block, conforming to the head and neck while allowing air circulation. This makes it a capable memory foam side sleeper pillow that combats heat. The cover is soft, quilted, and designed to wick heat away from the body.
Out of the box, the pillow is quite full and medium-firm, offering a high loft ideal for strict side sleepers. For back sleepers, removing approximately 1/4 of the filling (as suggested) creates a medium loft that prevents the head from being pushed too far forward. Stomach sleepers may need to remove up to 1/3 for a suitably thin profile. The adjustability makes it a true universal fit, allowing you to create your own best pillow for side and back sleepers configuration.
The outer cooling cover is machine washable, a significant advantage for hygiene. The shredded foam insert should only be spot-cleaned. Long-term durability appears good for most, though a small subset of reviews indicates the foam may compress and lose resilience over 12+ months of use. Fluffing and redistributing the filling periodically may help maintain its shape.
Value for Money
At its price point for a pack of two, the WISHSMILE pillow offers exceptional value. It combines features often found in more expensive models: adjustable fill, a specialized cooling cover, and a shredded foam construction that provides both support and breathability. For shoppers comparing it to a single, high-end gel memory foam pillow, getting two customizable pillows here is a compelling proposition.

We prioritized real-user experiences related to support (for neck and spine alignment), cooling efficacy, adjustability, durability over time, and value for money. Special attention was paid to feedback from side and back sleepers.
Data Sources
Analysis synthesized from over 6,400 Amazon customer reviews, focusing on detailed, verified purchase excerpts that discuss performance over weeks and months. Product specifications from the manufacturer listing were used to verify materials and features.
Note: The overwhelmingly positive reviews focus on initial comfort, cooling, and adjustability. Critical reviews primarily concern long-term firmness retention and initial odor, which are common considerations for memory foam products.
