Copper’s anti-bacterial and anti-microbial properties help to provide a cleaner sleeping environment and positively support overall health and well-being. Research has shown that copper can help to boost the immune system, increase circulation and reduce inflammation.
Premium hybrid construction is infused with copper for added support and comfort for a more restful night’s sleep. Features reinforced edge support, responsive and supportive individually wrapped coils that work in tandem with the comfort layers to conform to the body and minimize partner disturbance.

- Carefully slide compressed mattress out of box.
- Using the cutting tool provided, cut and remove outer plastic wrapping. The inner part of the vacuum-sealed plastic will remain intact.
- NOTE: Depending on the mattress you’ve received, you may need to unfold the compressed mattress after unrolling it, or you may just need to unroll it before removing final layer of plastic. Please take a moment to consider that before proceeding to the next step.
- Unroll and unfold (or just unroll) the mattress and position it on your base. Carefully cut and remove final layer of sealed plastic from the mattress.
- Carefully discard all packaging materials immediately after removal to avoid any hazard. Keep all packaging away from children.
- Allow your mattress to decompress naturally for the first 24–48 hours. Once it is fully expanded, manipulate the corners and sides to square it off as best as possible.

I love it!
After sleeping on a mattress I loved for many, many years, I purchased a queen size Immunity mattress for myself. It was time but I have high expectations and I was a little nervous about trying something new. Boy am I happy I did. I love it!
I was hesitant about buying a mattress that arrives in a box, but I took a chance. After sleeping on it for a couple weeks, it is the most comfortable mattress I have slept on. Was very easy to open and it unrolled to its full sizereally fast. ...
