Crafted a reputable mattress brand that's been in the industry since 1931, the Serta iSeries combines the best of memory foam and coils to deliver a truly restorative sleep experience. This mattress is made with quality CertiPUR-US certified foams, Serta's most advanced coil system yet, and multiple cooling technologies for a supremely comfortable sleep.

Pick the Serta iSeries if...

  • You want the best of memory foam and coils. Having a tough time deciding between memory foam and coils? With the Serta iSeries, you don't have to. You can get the best of cradling, body conforming comfort and resilient support from both!
  • You want a variety of comfort levels. The Serta iSeries is available in a variety of different comfort levels to suit a wide spectrum of sleep preferences and needs. If you like options, the Serta iSeries is a great choice.
  • You want to sleep cool. The Serta iSeries uses cooling foam layers, like their EverCool Fuze Gel foam, to control your temperature and pull away excess heat while you sleep. If you find that you sleep hot, the Serta iSeries might be a great solution.

Seek alternatives to the Serta iSeries if...

  • You want to buy your iSeries online, directly from Serta. Unfortunately, this model isn't available for purchase online, so you'll have to buy it online through a third party retailer, or visit an in store retailer to purchase. If this is an inconvenience for you, the Serta iSeries may not be the right choice.
  • You need a sleep trial. Because this model isn't bought online, it doesn't come with a sleep trial. If you need more than a few hours in a show room to make a decision about your new mattress, you may want to reconsider your interest in the Serta iSeries. A great alternative is Saatva. Not only do they provide a generous 180-night sleep trial, but you can order directly from their website!

Firmness/Feel/Comfort

The Serta iSeries is available in three different firmness levels to cater to a wide range of sleep preferences and needs. Here's a breakdown of each firmness level:

  • Plush: This firmness level is 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, Plush caters to this preference.
  • Medium: This is a firmness level ideal for all sleep styles, including back and stomach sleepers. Medium provides the cushioning you crave with the support you need for healthy spine alignment. This is also the most popular comfort level of all Saatva mattresses.
  • Firm: Firm is best for back and stomach sleepers who still want a mattress that provides adequate give and responsiveness.

Construction & Design

  • The Serta iSeries ranges from 13" to 13.5" tall.
  • Max Cold Cover: This mattress cover is made from temperature regulating, high performance fibers that create a cool-to-the-touch sensation.
  • Carbon Fiber Memory Foam: This high quality foam layer draws excess heat away from your body while providing optimal lumbar support.
  • EverCool Fuze Gel Foam: This cooling gel-infused foam layer further provides temperature control by increasing airflow and dissipating heat.
  • 1025 Hybrid Support System with Best Edge Foam: This advanced coil system uses individually wrapped coils that provide targeted support and adapt to your body's movements throughout the night. Best Edge foam encasement reduces roll-off and increases usable surface area.

Motion Isolation

Due to this mattress's advanced coil system, including 1025 individually wrapped coils, and quality layers of body conforming memory foam, the Serta iSeries is great at providing motion isolation. The coil system provides targeted support and reduces motion transfer across the bed, while memory foam layers absorb impact from sudden movements, allowing you to sleep undisturbed. For this reason, the Serta iSeries is great for couples.

Edge Support

Like this bed's motion isolation performance, the Serta iSeries performs exceptionally at edge support. The border of this mattress is encased in an extra deep high density foam rail which reinforces its edges. This means that more surface area can be used, and potential roll-off and sagging are greatly reduced.

Bed Frame Compatibility

The Serta iSeries is compatible with any bed frame, as long as the frame is the correct size for the mattress. Serta does create bed frames specifically designed to work with their mattresses though, which may be something to consider when purchasing an iSeries.

Shipping/Returns/Warranty

The Serta iSeries is only available through in-store purchasing, or through third party retailers, so shipping and returns are subject to this retailer's policies. The Serta iSeries is protected by a 10 year warranty.

Why Buy the Serta iSeries?

  1. You need back pain relief. As the iSeries is available in firm and features their most advanced coil system yet, the iSeries is a great choice for back sleepers who need extra lumbar support. Individually wrapped coils deliver the advanced support you need, while the memory foam layers are specifically designed to support your lumbar region.
  2. You sleep with a partner. This advanced coil system is additionally great for isolating motion, letting you sleep undisturbed regardless of your partner's movements.
  3. You toss and turn in your sleep. If you're a restless sleeper, the Serta iSeries might be a great solution. The Best Edge foam border prevents you from rolling off the bed, plus the body conforming memory foam layers will make it easier for your body to release tension and sleep still.

Why Avoid the Serta iSeries?

  1. You want a traditional innerspring. Perhaps you love the feel of a responsive innerspring, but the "sink in" feeling of memory foam isn't your thing. While this hybrid won't deliver that true sinking feeling, it won't be as firm or responsive as a traditional innerspring. If you're after this feeling, this mattress may not be for you.
  2. Three firmness levels isn't enough variety. While 3 different firmness levels cater to many different preferences, it certainly doesn't cover all the bases. If you're looking for a custom comfort level, check out Saatva instead.

Final Takeaway

The Serta iSeries is a, excellent if you want innovative memory foam and coil technology. This mattress is also surprisingly comfortable. You can get the Serta iSeries at a great price, today!
