Nectar Premier Copper Mattress

The Nectar Premier Copper is an all-foam mattress built around copper-infused gel memory foam, combining the deep pressure-relieving properties of memory foam with the thermal conductivity and antimicrobial benefits of copper. Its Triple Action Cooling system layers three distinct heat-management technologies: a Tencel cover infused with phase-change material (PCM), a copper-gel foam comfort layer, and a cooling memory foam transition layer, all working in concert to prevent heat buildup throughout the night. RTINGS.com testing awarded the Premier Copper a Motion Dissipation score of 8.6 out of 10, confirming its exceptional ability to absorb partner movement. At 14 inches of total height, the Premier Copper stacks multiple foam layers for a progressive feel that transitions from soft cushioning at the surface to firm core support below. The Medium Firm (6 out of 10) firmness level positions it well for back sleepers and those who sleep hot and need both contouring and thermal management without the excessive sinkage of a softer foam bed. Copper infusion also provides long-term antimicrobial surface properties, reducing odor and inhibiting bacterial growth over the life of the mattress. Nectar backs the Premier Copper with a 365-night home trial and their Forever Warranty, which never expires. These buyer protections are among the most generous in the mid-range category, making the Premier Copper a low-risk investment for hot sleepers who may need a full season to properly evaluate a new mattress. Trade-offs include below-average edge support compared to hybrid alternatives and no coil system for those who prefer a bouncier feel.
