The Serta iComfort mattress is available in a plush firmness level, optimal for side and combination sleepers looking for shoulder and hip pressure relief. If you like superior cushioning and feeling more "in" your mattress than "on" it, the Serta iComfort caters to this preference.

Construction & Design

  • The Serta iComfort is 10" tall.
  • Cold Touch Cover: The iComfort's breathable knit cover creates a cool-to-the-touch sensation to control your temperature and promote airflow.
  • Carbon Fiber Memory Foam: This memory foam layer uses carbon fiber to pull excess heat away from the body while providing pressure relief to your neck and back.
  • EverCool Fuze Gel Memory Foam: This gel infused memory foam layer provides additional cooling while cradling common pressure points like your hips and shoulders.

Support & Motion Isolation

The Serta iComfort is an all-foam model made with quality memory foam layers, so it performs pretty well at motion isolation. Without any spring system to generate unwanted bounce, the memory foam and foam layers provide isolated support and comfort, while the bottom layers absorb excess motion, leaving the other side of the bed relatively undisturbed.

Unfortunately, the Serta iComfort has no defined edge support system. Without proper edge support, the iComfort could sag over time and create that dreaded roll-off feeling. It could also be less durable than mattresses with proper edge support, like all Saatva models.

Reasons to Buy the Serta Walnut Creek mattress replacement, the Serta iComfort mattress

  1. You sleep on your side. If you sleep on your side, the iComfort's plush firmness level is suited well to your sleep style. The pressure relieving foams cradle your shoulders and hips while supporting your spine for a great combination of comfort and support.
  2. You share your bed with someone. The iComfort's all-foam construction limits motion transfer by absorbing energy created by excess movement and keeping the bed's surface neutral. Both you and your partner will sleep undisturbed.
  3. You toss and turn in your sleep. If you're a restless sleeper in search of relief, the iComfort is an excellent choice. The memory foam layers cradle pressure related-areas to provide comfort, so you'll be encouraged to sleep soundly instead of moving to avoid pain.

Reasons to Avoid the Serta Walnut Creek mattress replacement, the Serta iComfort mattress

  1. You prefer a firm comfort level. The Serta iComfort is only available in a plush firmness level, which might be too soft if you prefer your mattress on the firmer side. Consider Saatva instead, which offers a variety of firmness levels with nearly every mattress they make.
