The Alexander Signature Hybrid is designed with options and versatility in mind. Nest streamlined the process by building this mattress with a zipper. So if you choose one firmness feeling and decide during your sleep trial that you want something different—then you can just unzip your mattress and put a new comfort layer inside.
*Dual Firmness Option*
In the King and California King size options, there is also an option to get a mattress that is customizable to make each side a different firmness feel (plush, medium or firm). They call it an “internal split” and this is a perfect option for couples who have completely different firmness preferences.
How is the Alexander Signature Hybrid Mattress constructed?
Cover: The cover is a soft fabric quilted with a Thermic Phase Change Top; this innovative material excels at changing from solid to liquid in response to heat. So if you’re worried about breathability or sleep hot, this cover helps to dissipate body heat and promote cooling instead.
Comfort Layers: This mattress contains three comfort layers. First up is 0.4 inches of gel-infused memory foam to enhance the cooling benefits. Next is 3 inches of 3.5 lb TitanChil Endurance Foam which is a hyper-elastic design for immediate response when adjusting your position. Lastly is 1 inch of Nest’s SmartFlow polyfoam. This layer has punched layers to maximize airflow while also separating the softer layers from the firmer core.
Support Layer: Similar to most hybrids, this layer features 8 inches of 16-gauge pocketed support coils that are zoned for support and reinforced around the edges. The outer coils are made to be lower gauge (thicker) and the inner coils are higher gauge (thinner). As such, this layer does a good job at providing more responsiveness and bounce in the centre, while keeping the entire surface stable.
Base Layer: At the bottom of the mattress is a 1-inch, 3 lb polyfoam layer that helps the coils above bounce and activate.
