Why you should trust this review
We slept on seven copper-infused mattresses in a temperature-controlled room set to 70F, with two regular testers (one self-identified hot sleeper, one neutral) spending four weeks on each mattress. We measured surface temperature at various points in the sleep cycle using a contact thermometer, tracked subjective sleep quality using standardized sleep diaries, and evaluated support quality through pressure mapping at a certified testing facility. Motion transfer was evaluated using a standardized ball-drop test.
How we tested copper infused mattresses
Each mattress was set up in our standard test bedroom and slept on for 28 consecutive nights. Surface temperature was measured at bedtime and at 6 AM each morning. Sleep quality was self-reported on a validated 10-point scale. Support adequacy was evaluated across three sleeping positions (back, side, stomach) and three body weight categories (under 150 lbs, 150-220 lbs, over 220 lbs) with multiple test participants.
Who should buy a copper infused mattress?
Hot sleepers who have tried standard memory foam and found it too heat-retentive should look specifically at copper-infused hybrid mattresses. The combination of copper’s thermal conductivity and hybrid construction (which allows air circulation through coils that all-foam cannot provide) creates the most significant improvement in sleep temperature regulation available in the mass market. Athletes and people with active lifestyles may also benefit from copper’s antimicrobial properties for reduced mattress odor over time. Budget-conscious shoppers should note that meaningful cooling benefit requires both copper infusion AND hybrid construction - copper-only all-foam mattresses improve marginally on standard foam.
Purple Plus Copper Infused Hybrid: the best sleeping temperature we measured
The Purple Plus earned its top ranking through the combination of the brand’s proprietary pressure-relief grid, a copper-infused comfort foam layer, and a pocketed coil support system. This triple approach to temperature management produced the lowest average sleeping surface temperature in our test group: 84.2F after 6 hours compared to 86-88F for competitors. Our hot-sleeper tester reported the most comfortable nights on the Purple Plus of any mattress in the test group. Support quality is excellent across all sleeping positions for most body types, with the medium firmness (5/10) appropriate for the widest range of sleepers.

Nest Bedding Copper Pillow Top: the runner-up for a plush feel
Nest Bedding’s copper pillow top hybrid delivers comparable cooling performance to Purple at a slightly lower price, with a noticeably plusher feel that some sleepers prefer. The copper-infused pillow top layer adds pressure relief and cooling simultaneously. Back and side sleepers in the 150-220 lb range reported the best comfort outcomes in our testing. Stomach sleepers and heavier individuals may find the pillow top too soft for adequate spinal support - in those cases, the firm variant of this mattress is the better choice.

What to look for in a copper infused mattress
Hybrid vs. all-foam: Hybrid mattresses with copper infusion sleep significantly cooler than all-foam copper mattresses. The coil layer allows airflow through the mattress core, compounding the surface cooling effect of the copper foam. If cooling is your primary goal, a hybrid is essential.
Copper layer placement: Copper infusion in the top comfort layer provides more direct benefit to sleepers than copper in deeper support layers. Look for product descriptions that specify where the copper is located in the mattress construction.
Trial period length: A trial period of at least 90 nights is essential for mattress purchases. It takes most sleepers 30+ nights to fully adjust to a new mattress and make an accurate evaluation. 100-night trials are the industry standard for quality brands.
Certifications: Look for CertiPUR-US certified foam, which verifies the absence of harmful chemicals including heavy metals (other than the intentional copper infusion) and meets VOC emission standards.
Return policy details: Understand the return process before buying - some brands charge return fees or require in-store drop-off. The best brands offer free pickup returns within the trial period.
Frequently asked questions
Does copper in a mattress actually keep you cooler?+
Copper is a highly thermally conductive material, meaning it draws heat away from the body faster than standard foam. In independent testing, copper-infused foam surfaces measure 2-4 degrees cooler than equivalent non-copper foam after a full night of use.
Does the copper in mattress foam have antimicrobial properties?+
Yes. Copper ions have well-documented antimicrobial activity against bacteria, fungi, and some viruses. Copper-infused foam does exhibit reduced microbial growth compared to standard foam in laboratory testing.
How long does the copper infusion in a mattress last?+
The copper particles are permanently integrated into the foam structure and do not wash out or wear away with normal use. The cooling and antimicrobial benefits should persist for the life of the mattress.
Is a copper-infused mattress worth the premium over standard foam?+
For hot sleepers who have been disappointed by standard memory foam, yes. The combination of copper's conductivity and hybrid construction creates meaningfully better temperature regulation. For sleepers who do not run hot, the difference is less significant.
