Frequently asked questions
Copper vs graphite vs gel?
All conduct/absorb heat to different degrees: gel absorbs then saturates, copper and graphite keep conducting. Copper sits between plain gel and Saatva's graphite in our warm-night testing.
Antimicrobial claims real?
Copper's antimicrobial effect is documented in textiles; in a covered topper it's a hygiene bonus, not a health feature.
Worth it over Lucid gel?
If warm nights are your constant complaint, the ~$20 step up earns itself; otherwise plain gel does the job.
Cover included?
Yes — washable, which budget bare-foam rivals skip.
