Serta iComfortECO Foam vs Spindle

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.

Spindle's unique design gives us options if we need to tweak your comfort. You have up to 365 days to determine if an all-latex mattress fits your needs. If we can't get you comfortable we'll refund your money. The medium is a great choice for most people. The mattress ships with one layer of firm latex and two layers of medium. You fine-tune your bed to reach your personal ahhhhhhhh. You no longer have to lose sleep over which firmness is right.

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.

Spindle is the natural and organic mattress you've always wanted, at a price that makes sense. Constructed with the following layers:

• Organic Cotton Cover
• Eco-Wool Batting
• 9" 100% Natural Dunlop Latex (Three 3 inch layers of various firmnesses, based on your preference).

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.

Eco Wool Batting offers a chemical free flame barrier between the latex and you. No chemical flame retardants; no chlorinated or brominated solvents. The sheep are raised humanely and the wool is processed in accordance with the Eco-Wool guidelines.

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

Unlike most foam beds, Spindle's latex retains a traditional springiness that removes any sensation of being stuck - the benefit of latex foam is a healthy bounce.

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.

Natural rubber provides a unique sleeping experience that provides great support and cushion. It has a mellow feel that many find more comfortable than other mattress designs. Manufactured in the USA without any fillers or synthetic latex and is certified by FSC, Rainforest Alliance, and Oeko-Tex. Providing a safe and comfortable sleep environment.

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.

Natural latex provides a sleep surface that conforms to your body with minimal sink. It helps relieve pressure from the hip and shoulder areas, allowing the contours of your body to be properly supported. Customers describe the sensation as an up lifting experience.

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.

In our top quilting, we use an organic cotton circular knit fabric. This results in an incredibly flexible and stretchy case that helps you experience the true feel of latex. Our fabric is certified to the GOTS standard and produced without pesticides, pigments or bleach. Reducing your exposure to chemicals found in other mattresses.
