Serta iComfortECO Foam vs Tuft & Needle Nod

The base model (CF1000) is a medium comfort. Choose the cooling upgrade (CF2000) model if you prefer a firm feel. Both the Max Cooling Upgrade (CF3000) and Max Cooling & Pressure Relief Upgrades (CF4000) offer a selection of feels - medium, plush, ultra plush and firm, plush, ultra plush.

The Nod mattress offers a medium firmness, so it's perfectly in the middle in terms of feel. It's soft to the touch, but very supportive when you lay out on the surface as it responds to your weight.

With the iComfort by Serta® mattress, cool, supportive sleep is the priority. The base model (CF1000) has these layers:

• Carbon Fiber Memory Foam
• EverCool® Fuze Gel Foam.

Exclusive to Amazon, the Nod is 100% polyurethane foam and not comprised of their proprietary T&N Adaptive foam. It has 2 layers of construction:

• 2.5" Comfort Layer of Responsive Foam
• 5.5" Supportive Base Layer.

Specifically designed mattress to keep even the warmest of sleepers cool. You don't have to be a hot sleeper to love iComfort. You just have to like your sleep environment to be refreshingly comfy. Three cooling upgrades available:

• Cooling Upgrade (CF2000): 11.5" Additional cooling and firmer support.
• Max Cooling Upgrade (CF3000): 12.5" Cooler and more breathable.
• Max Cooling & Pressure Relief Upgrade (CF4000): 13.5" Feels and sleeps cooler, with air support layer to take pressure off joints.

The foam used in the Nod mattress is an open-celled polyurethane foam that we engineered to have the benefits of memory foam's pressure relief and latex's support, without their drawbacks (like memory foam's sinking and sleeping hot, and latex's lack of pressure relief). That said, both memory and synthetic latex foams are subsets of polyurethane foam.

Multi-layered foam technology adds support, resilience, and temperature regulation for the coolest, most comfortable sleep ever.

Being comfortable isn't all about a soft top layer, we designed our mattress to give you the support you need for a restful night's sleep.

Every iComfort mattress is made with our exclusive Carbon Fiber Memory Foam. This system channels heat away from your body.
Gel Active® Max Foam (used only in CF2000 model) is an open celled memory foam helps promote airflow, so you don't have that hot, stuffy feeling when falling asleep.
UltraCold System™ (used in the CF3000 and CF4000 models) The layer of extra-cool Carbon Fiber Memory Foam is engineered to work hard at absorbing excess heat from your body, then channel it away, all while you sleep comfortably.

We chose an open-cell foam which allows air to freely flow throughout the night, overcoming foam's reputation for sleeping hot.

Carbon Fiber Memory Foam provides exceptional strength for back and neck support.
Air Support™ Foam (used only in CF4000 model) moves with your body and contours around it to help alleviate aches and pains caused by pressure points.

We designed our top layer to be adaptive without feeling like quicksand - cradling your pressure points and meeting you where you are.

A Max Cold™ Cover is used in the CF3000 and CF4000 models. Made from super cool high-performance fibers for an instant cool-to-the-touch sensation.

The Nod Mattress cover is a viscose/polyester blend.
