The Diamond Dreamstage 2.0 Calm Quilted Mattress delivers cloud-like luxury at a towering 15-inch mattress profile height.

It allows sleepers to choose Firm, Medium, or Plush feels. The tall build adds generous cushioning while preserving support.

Next, a cooling quilted cover rests above copper-infused memory foam. Both layers use CertiPUR-US certified performance foam. And a zone of individually wrapped coils anchors this 15-inch quilted hybrid mattress.

Moreover, this design supplies targeted spinal alignment support and minimal motion transfer for partners. It works as the ideal high-profile 15-inch mattress for couples who value uninterrupted rest.

Lastly, this mattress will be delivered to US buyers free of cost. You’ll also receive a 120-night risk-free sleep trial and a twenty-year warranty. 

There’s also flexible Diamond mattress financing available at checkout, which can lower the upfront cost.
