Which Serta iComfort Mattress Should You Get?

Serta offers five iComfort mattresses that boast several different features and firmnesses. Let’s look at each model one by one and discuss who should choose each one.

  • Serta iComfort LE: This is the most basic, affordable iComfort model that has a plush firmness. If you are on a tighter budget or are a lightweight sleeper or side sleeper, this model offers everything you need.
  • Serta iComfort CF1000: This iComfort boasts more cooling features and has a medium firmness. Being medium-firm, it should be a great fit for back sleepers. It will also perform well if you sleep hot, but don’t need the more advanced cooling materials found in the higher-end models.
  • Serta iComfort CF2000. The CF2000 is one of the firmest models in the iComfort line. Take a look at the CF2000 if you are a stomach sleeper or back sleeper who prefers something on the firmer end.
  • Serta iComfort CF3000. This is one of the coolest-sleeping mattresses in the iComfort line as it contains very advanced cooling materials. You can also choose from multiple firmness options, so it should work for hot sleepers of any sleeping position.
  • Serta iComfort CF4000. This is the most luxurious iComfort model, making it a good fit if you want the most luxurious mattress. It features both maximum cooling features as well as a Pressure Relief Upgrade. If you are a side sleeper or hot sleeper who wants the best pressure relief and cooling, the CF4000 is the way to go.

Serta iComfort Mattresses Construction

Now, let’s get into exactly what’s going on inside these five mattresses. We’ll discuss the materials and how they affect the performance of each mattress.

Serta iComfort LE Construction

The LE features Serta’s proprietary Cold Touch™ cover. This is a knit cover that is cool to the touch and is designed to cool you down the moment you lie down.

The mattress contains EverCool® Fuze Gel Foam and EverCool® Fuze Gel Memory Foam. As the names suggest, they are both intended to keep you cool at night. Both are infused with cooling gel, a material known for its heat-dissipating qualities.

Firmness: Plush

Serta iComfort Model CF1000

The CF1000 features the same Cold Touch™ cover found on the LE mattress. In addition, it boasts the same cooling and pressure-relieving EverCool® Fuze Gel Memory Foam. This mattress differs from the LE in that it contains Carbon Fiber Memory Foam, which is designed to draw heat away from your body while also offering great back and neck support.

Firmness: Medium

Serta iComfort Model CF2000

The CF2000 features a cooling upgrade and adds a layer of Gel Active® Max Foam to the construction. This material is more breathable than standard memory foam and helps promote airflow through the mattress. The CF2000 also contains the same Carbon Fiber Memory Foam you find in the CF1000.

Firmness: Firm

Serta iComfort Model CF3000

The CF3000 comes with the Max Cooling upgrade. This includes the addition of a Max Cold™ Cover, made with high-performance fibers for maximum cooling. It also boasts the UltraCold™ System that will absorb your body heat and channel it away from your body.

Depending on which firmness you choose, the mattress may also contain EverCool® Fuze Gel Memory Foam and EverCool® Supreme Memory Foam for even more pressure relief and comfort.

Firmness: Medium, Plush, Ultra Plush

Serta iComfort Model CF4000

This is the most luxurious iComfort model that contains Max Cooling and Pressure Relief upgrades. Like the CF3000, it also features a Max Cold™ Cover, and UltraCold™ System. In addition, it contains Air Support™ Foam, which is designed for superior pain and pressure relief. If you choose the ultra plush model, the mattress will also feature EverCool® Supreme Memory Foam.

Firmness: Firm, Plush, Ultra Plush

What Types Of Beds/Frames Do They Work With?

According to a Serta sales representative, all iComfort memory foam mattresses will work with any standard bed frame. They do advise that owners use a box spring or a solid foundation as it helps with the stability of the mattress.

One thing to note is that if an old foundation somehow manages to damage the mattress, it will void the warranty.
