Patented Support System: Center Zoned Nested Wrapped Coils
Foam Encased Design

This Transformation mattress is 10-inch in height and has the same base as the other collections from Diamond, i.e. a zoned support system with 25% more coils in the center of the mattress and also a 2-inch layer of HD comfort foam.

Unique to this hybrid mattress is the micro-coil comfort layer that tops the base layers, consisting of over 1,000 micro-coils that provide weightless pressure relief, increased airflow, and reduced motion transfer across the mattress.

Then, this Transformation mattress has another layer of Diamond Sparkle memory foam topped with the Cool Touch Advanced fabric.

Transformation Mattress Firmness

This hybrid mattress is available in Plush, Medium, and Firm. The Plush bed is rated as a 3/10, while the Medium is rated as a 5/10, and the Firm is rated as an 8/10.

The Medium mattress provides an excellent middle ground that should suit all couples with different sleep preferences, and different sleep styles (i.e. back, side and stomach sleepers).

Mattress Cooling and Motion Control

This Transformation mattress will perform best in terms of cooling: it features the Sparkle foam, which draws moisture and excess heat away from your body, as well as Diamond’s specialist Cool Touch Advanced Phase Change Material, which regulates your body temperature as you sleep for full comfort.

Additionally, the micro-coil layer further serves to enhance airflow through this mattress, allowing the other cooling features to dissipate heat easier, for a cooler sleep surface.

This is also the best mattress out of the Diamond mattress collections in terms of motion control, because the additional layer of micro-coils helps to isolate motion fully, even if your partner tosses and turns around, next to you.

Overall, this Transformation mattress is Diamond’s most premium bed, with a slighter higher price-point to match, but the benefits are huge. If you’re looking for an hybrid mattress with lots of cooling features that also offers deep support and pressure relief, this model ticks all the boxes in the selection process.
