The Best iComfort Mattress by Sleeping Position

Side Sleepers

Recommended: CF4000 (Plush Version), CF1000

Side sleepers need mattresses that will conform to their body to keep pressure off their hips and shoulders and to promote spinal alignment. That is why we advise side sleepers to seek out mattresses on the lower end of the firmness scale. With the iComfort line, we recommend the CF4000’s plush version because of its included Air Support Foam, which moves with your body and contours around it to alleviate pressure points.

Back Sleepers

Recommended: CF3000, CF4000 (Firm Version)

Back sleepers need firmer mattresses that prevent their head, feet, and hips from sinking. A mattress that is too soft may cause your spine to become misaligned, so you want something that is in the medium firmness range. All three of the iComfort models work for back sleepers if you want more cushioning, but when selecting the CF4000, we advise you to pick the firm version for ultimate comfort.

Stomach Sleepers

Recommended: CF3000, CF4000

Stomach sleepers require even greater support than back sleepers in order to keep their spine properly aligned. There is also the need for additional support on the neck because stomach sleepers keep their heads turned to the side. Similar to back sleepers, we recommend stomach sleepers go with one of the more supportive iComfort models, like the CF3000 or CF4000 firm.

iComfort Materials

iComfort mattresses use only the best materials to ensure your body gets the support it needs.

Carbon Fiber Memory Foam

iComfort mattresses are composed of Serta’s exclusive Carbon Fiber Memory Foam material, which reduces body temperature by channeling heat away from you while you sleep. This proprietary memory foam also provides extra support for your back and neck.

Max Cold Cover

The Max Cold Cover is made of super cool high-performance fibers, giving sleepers an instant cool-to-the-touch sensation.

Air Support Foam

If you have aches and pains caused by pressure points, you’ll be pleased to know that the Air Support Foam moves with your body and contours around it. This promotes spinal alignment and delivers additional comfort for all kinds of sleepers.

Gel Active Max Foam

The Gel Active Max Foam is an open-celled memory foam that promotes airflow. If you’re a sleeper who gets that hot, stuffy feeling at night, that worry will be a thing of the past.

Maintenance and Care

Caring for your mattress is necessary if you want it to last. In case of a stain, we recommend adding baking soda to the soiled area and letting it sit for approximately 15 minutes. Afterwards, you can vacuum it up and air out the mattress.

Do not apply any type of liquids to the mattress because they can potentially stain the fabric and make the stain worse. The foam inside the mattress can break down prematurely if exposed to chemicals or moisture, so we recommend that you use a mattress protector.

The iComfort CF1000 Mattress Construction

On top of the CF1000 mattress you’ll find a cool-to-the-touch cover for temperature regulation. Underneath that is a unique memory foam layer with carbon fiber to promote cooling, strength, and back support. Next is 3” of Evercool Fuze gel memory foam, which conforms to your body’s curves for additional comfort.

After the gel foam layer is the support layer, which uses support foam to provide pressure point relief. Finally, the Serta foam core delivers a solid foundation and gives you conforming support.

The iComfort CF3000 Mattress Construction

The Max Cool Cover is made from super cool high-performance fibers to give an instant cool-to-the-touch sensation. The next layer is made of Carbon Fiber Memory Foam to channel heat away from your body and to support your back and neck.

Then there are two layers of Deep Reaction Max Memory Foam to further enhance the mattress’s ability to dissipate heat. Finally, the Serta core of the mattress creates a strong foundation and support for sleepers.

The iComfort CF4000 Mattress Construction

The CF4000 is available in a plush model and a firm model, depending on what level of firmness you desire. Both models have Cool Touch covers to deliver cool-to-touch sensation.

Next is the Carbon Fiber Memory Foam layer to give you exceptional back and neck support while also channeling heat away from your body.

The following layer on the plush mattress is the 3” EverCool Supreme Memory Foam for cradling comfort and to relieve pressure points, while the firm model uses a Deep Reaction Max Memory Foam technology to help with heat dissipation and to enhance the overall comfort level for back sleepers.

The next layer on the plush model is an Ultra-Cool Phase Change Material layer to provide a cooler sleep surface, letting you fall asleep faster.

The following layer utilizes Serta’s exclusive air-cushion technology that moves with your body, contouring around it to further relieve aches and pains. The Serta Foam Core is the firm component of the bed that acts as a support system and foundation.

The Serta Buying Experience

Serta iComfort Trial-Period

All mattress purchases made through Serta’s website are covered under a 120-day in-home trial. The day your mattress is delivered to you, you have 120 days to see if it meets your sleep needs.

Serta recommends that you allow for a two-week break-in period to let your body adjust to the new mattress. If you find that you’re still not happy with your iComfort, you can contact Serta by phone or by email and set up your hassle-free return, at no cost to you.

Serta will arrange to have your mattress picked up and removed from your home. If you purchased your iComfort from another retailer, you must reach out to them to handle returns.

Another option if you’re unhappy with your mattress is to consider an exchange. Within the 120-day in-home trial period, you are welcome to contact Serta about exchanging for a new item.

When you call Serta, they will walk you through the exchange process, place your new order over the phone, and charge the difference or return the difference to your payment method. It’s important to remember that an exchange will void the 120-day trial period on your new product.

If you choose the additional White Glove Delivery option, XPO will not only set up your new mattress, but they will also remove your old mattress and box spring.


Serta has partnered with Affirm to give customers the option of financing their new mattresses. When you reach the checkout page, you can select the pay-through-Affirm option.
