A Better Sleep Experience

Cooling Cover. Copper Technology. Pressure-Free Comfort.

Stay cool, supported, and well-rested with our 12” Copper Infused Memory Foam Mattress—crafted to deliver a refreshing sleep experience night after night. This thoughtfully engineered mattress features advanced copper-infused memory foam, a cool-to-the-touch breathable cover, and an adaptable core that works seamlessly with adjustable bases.

Key Features:

  • Copper conducts heat away from your body, helping regulate temperature while you sleep. It also offers natural antimicrobial and odor-reducing properties, creating a cleaner, more comfortable sleep surface.
  • Multi-layered foam contours to your shape, cushioning key pressure points like the hips and shoulders while promoting proper spinal alignment—reducing tossing and turning throughout the night.
  • Wrapped in a high-performance knit cover infused with cooling yarns, this soft and breathable fabric enhances airflow and delivers instant surface-level coolness.
  • Flexible and supportive, this mattress bends easily with adjustable frames—offering full-body comfort in any sleep position.

Super Comfy and GREAT service

I tried ordering online, but didn't trust myself so I called. Everyone at the plant was REALLY kind and helpful. Great service.
The mattress is super comfortable and the split CA king set up is the bomb. Sheets are soft and cool too. Great purchase!!

Love this bed!

The mattress and adjustable base arrived in perfect condition. I did hire someone for assembly as i am a 60 something woman and the base is very heavy. It all came together and fit perfectly with my antique bedframe. I happened to get sick soon after but this bed made the whole episode easier, allowing me to sleep with my head raised a bit and watch TV without neck pain. I've been falling asleep very quickly and wake without pain. I'll say it again: I LOVE THIS BED!

Great mattress, great price!

After several years thinking about getting a zero gravity elevating bed, I did it and I am glad. My mattress was oldish but still good so thought it would be best tp buy a nrw one from the same company as the bed frame. 12" worked for me and I findd the mattress to be comfortable and good quality. I am very happy with my purchase.

It's been a life saver!!

I really enjoy this mattress. It's firm enough to prevent sinking and twisting of your back yet still cushions the joints. I am recovering from many broken bones and I can finally get comfortable with the adjustable bed. It's so much more comfortable than the rented hospital bed.
Awesome price too!! I have all the bells and whistles and my bed still was a couple grand cheaper than my daughter's adjustable bed with the same options. Tyvm for quick shipping. It was quite easy to assemble. Overall, I'm a very happy customer.

My husband uses it on a 'movable' bed frame and the mattress goes accordingly.

Appreciated the option of "white glove" because we are an older couple who could not lift or remove old mattresses by ourselves. Delivery team was excellent!

My Wife is Pleased

We started with 2 Firm gel foam mattresses, split California King. I loved mine, but my wife said it was not to her liking as it left her hurting on her hips and shoulders sleeping on her side. So back it went under the return program. It was replaced with the medium firm copper gel infused. It’s a winner! Now we both are super pleased with our mattresses, and Blissfulnights honored their return policy. Now that’s a great business!

Best nights sleep

We recently moved and did not bring our adjustable bed. I purchased this bed online and was a little fearful it wouldn’t live up to our old bed that cost thousands on dollars more. The bed is perfect. My husband and I both have health conditions that are painful. The mattress gives us both the best nights sleep, not only do we sleep through the night but we don’t hurt when we wake up.
