Why you should trust this review
We evaluated 10 bed covers over three months using our standard hot-sleeper test panel (five testers who report regular night sweating). Each cover was tested for at least 14 consecutive nights per tester. We measured skin microclimate temperature (heat trapped between body and cover) using calibrated sensors, and had testers rate their perceived sleep comfort and body temperature at morning wake time.
How we tested cooling bed covers
Temperature sensors were placed at the torso-cover interface for each test night. We averaged readings from 11pm to 6am and compared each cover against a standard 300-thread-count cotton control cover. We also assessed subjective comfort ratings from our testers, focusing on whether they woke feeling overheated, sweaty, or comfortable.
Durability was assessed at 30 wash cycles for fabric integrity and color retention.
Who should buy a cooling bed cover?
Hot sleepers who wake up uncomfortably warm or sweaty, those in warm climates without air conditioning or with inconsistent AC, and those whose sleeping partner prefers different temperatures. A cooling bed cover is one of the most impactful changes a hot sleeper can make to their sleep environment without replacing a mattress.
Buffy Cloud Eucalyptus Cover: The best cooling bed cover
The Buffy Cloud Eucalyptus Cover reduced our test panel’s average skin microclimate temperature by 2.1 degrees F compared to the cotton control — the largest reduction of any cover we tested. The eucalyptus lyocell (TENCEL Lyocell from eucalyptus pulp) achieves this through its superior moisture management: it wicks moisture away from the skin 50% faster than cotton in our absorption tests, reducing the clammy feeling that wakes hot sleepers.
The sateen weave provides a silky-smooth texture that four of five testers rated as the most comfortable surface of any cover we tested. Unlike cotton sateen which can feel warm and heavy, the eucalyptus version maintains a cool-to-touch sensation throughout the night.
At 30 wash cycles, the cover maintained its cooling properties and softened slightly — the characteristic behavior of quality lyocell fabrics.
LUXOME Bamboo Duvet Cover: Best value cooling bed cover
The LUXOME bamboo duvet cover provides very good cooling performance at $99 — a meaningful savings over the Buffy’s $175. Our skin microclimate tests showed a 1.7-degree F reduction vs. cotton control — somewhat less than the Buffy but still significant for hot sleepers. The bamboo viscose fabric is softer than many cotton alternatives and breathes well in our testing.
The LUXOME is the right choice for buyers who want meaningful cooling improvement over standard cotton covers without paying the full premium for eucalyptus lyocell.
What to look for in a cooling bed cover
Material: Eucalyptus lyocell and bamboo viscose are the top cooling materials. Percale cotton (100% cotton with a tight weave) is a good budget-friendly cooling option. Avoid polyester and microfiber covers if you sleep hot.
Thread count: In natural fiber covers, look for 200-400 thread count. Higher thread counts in cotton can actually reduce breathability. In bamboo and eucalyptus, the weave construction matters more than thread count.
Weave style: Percale (crisp, cool) vs. sateen (silky, slightly warmer). For maximum cooling, percale is slightly better. For softness with cooling, sateen in eucalyptus lyocell is the best combination.
Closure type: Zipper closures hold the duvet more securely than button or tie closures. Look for full-length zipper or corner ties to prevent duvet shifting.
Weight: Lighter covers breathe better. If you are buying specifically for cooling, avoid heavy or quilted covers.

Frequently asked questions
What material is best for a cooling bed cover?+
Eucalyptus lyocell, bamboo viscose, and percale cotton are the best cooling materials for bed covers. They are breathable, moisture-wicking, and feel cool to the touch. Avoid polyester and microfiber, which trap heat.
Will a cooling bed cover help with night sweats?+
Yes, breathable materials reduce the heat buildup that triggers night sweats. Combined with a cooling mattress topper or cooling sheets, a eucalyptus or bamboo cover can significantly reduce night sweating.
Do I need a special duvet with a cooling cover?+
A cooling cover works with any duvet but works best with a lightweight or temperature-regulating fill. Pairing a heavy down duvet with a cooling cover reduces but does not eliminate the heat trap from dense fill.
How do I wash a eucalyptus bed cover without damaging it?+
Machine wash cold on a gentle cycle with mild detergent. Tumble dry low. Avoid bleach and fabric softener. Do not over-dry. Eucalyptus lyocell weakens when wet, so avoid aggressive agitation.
