Upgrade to the Diamond Response Copper Hybrid Mattress. A 12-inch copper hybrid mattress that ships straight to your door. 

A cool-to-the-touch fabric pulls excess heat away instantly, while a layer of antimicrobial copper-infused foam not only stays fresh but actively disperses body warmth so hot sleepers rest easy. 

Beneath, high-density transition foam and a temperature-regulating hybrid construction cradle curves without the “stuck-in-sand” feel. 

At the core, 740 individually wrapped coils flex independently for targeted support and edge-to-edge support system stability, so couples can stretch out in luxury. 

Choose either Firm or Medium to match your preference. Either way, you’ll enjoy restorative sleep with cooling comfort and a plush Euro-top finish. 

Covered by a Diamond Mattress 20-year warranty and backed by a 120-night risk-free sleep trial, it’s the worry-free path to deeper ZZZs.

WE'VE GOT ANSWERS

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

Choose Medium (balanced plush-support feel) or Firm (extra back support) to suit personal preference.

Yes. Copper particles draw heat away and are naturally antimicrobial, helping the surface stay drier and fresher.

The tri-zone coil core supports the lumbar while relieving shoulder pressure, so back, side, or combination sleepers report equal comfort.

Most hybrid profiles flex fine on modern power bases. If you plan to pair with an adjustable frame, check hinge clearance or choose Cloudy’s Add Adjustable Bed bundle for guaranteed fit.

Typical in-box hybrids reach full height within 24 hours. Light off-gassing is normal and dissipates quickly in a ventilated room.
