Product/catalog imagery is for identification, not proof of an in-house physical test.
Rest Evercool+ is a synthetic performance-knit pillowcase marketed for a cool initial feel. It changes the contact surface rather than the pillow’s fill, loft, or support.
Rest publishes laboratory cooling claims, but its current product page shows different Qmax figures in different sections. We do not treat a single figure as settled or as proof of all-night cooling.

From $79 — check current pricing and selected options.
Consider it if you want a washable synthetic cooling-knit pillowcase. We have not tested its temperature or feel; compare fabric preference, size, care instructions, and current price.
What the evidence tells us
We do not assign numerical ratings to research reviews. Specifications alone cannot establish comfort, overnight cooling, pressure relief, or long-term durability. Compare the documented construction and fit below; any logged hands-on measurements appear in the testing record above.

What the cooling claim can tell you
A contact-cooling claim describes the fabric surface. It does not establish how long the pillowcase stays cool in your room or how the underlying pillow handles heat.
Rest’s current page contains inconsistent Qmax figures. Confirm the relevant model and supporting report with the brand if that number is central to your purchase.
Compare the material and care
This is a synthetic knit rather than mulberry silk. Choose based on your fabric preference and exact care label; we have not measured which feels smoother or lasts longer.
A washable cover still needs the right cycle and drying instructions. Do not infer that antimicrobial marketing eliminates regular washing.
Who should consider it
It may interest shoppers who want to change the contact fabric while keeping a pillow that already fits. It will not fix unsuitable pillow height or shape.
Cooling bedding is not a treatment for persistent night sweats or other symptoms.

How this review was researched
We have not slept on this pillow. This review is based on manufacturer specifications and our research — published materials, dimensions, care instructions, trial and warranty terms, certifications — plus how those specs compare with pillows we know well in the same category. We do not present any of it as first-hand experience.

Final verdict
Evercool+ is an option for changing the surface fabric without replacing your pillow. Treat its cooling claims as manufacturer claims, confirm the current care directions, and do not expect the cover to correct a poor pillow fit.

Frequently asked questions
Does a cool-touch claim prove all-night cooling?
No. The contact surface, room, bedding, and underlying pillow all affect the experience. Mr. Squish has not measured overnight temperature with this case.
Is Rest Evercool+ cooler than silk?
We have not tested them side by side. Rest publishes fabric comparisons, but those claims do not establish an overnight result for every sleeper.
Can I use it on a cooling pillow?
Use a correctly sized case compatible with the pillow’s care and fit requirements. Adding a case does not guarantee a cooling benefit.
