Seek alternatives to the Serta iSeries Hybrid 500 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 Hybrid 500 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!


The Serta iSeries Hybrid 500 has a cushion firm firmness level, which is ideal for all sleep styles, including back and stomach sleepers. Cushion firm 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.

Construction & Design

  • The Serta iSeries Hybrid 500 is 14" tall.
  • Hyperfeel Cover: The Hyperfeel cover delivers touchable soft comfort combined with a cool-to-the-touch sensation for comfortable temperature control.
  • Cool Reaction Memory Foam: This high quality foam layer draws excess heat away from your body while providing optimal lumbar support.
  • EverCool Supreme & Twist Memory Foam: These cooling gel-infused foam layers further provide temperature control by increasing airflow and dissipating heat.
  • 886 Pro-Support Coil 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

With an 886 coil count system and quality layers of body conforming memory foam, the Serta iSeries Hybrid 500 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 Hybrid 500 is great for couples.

Edge Support

The Serta iSeries also performs well 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. Avoid placing your mattress directly on the floor!


The Serta iSeries Hybrid 500 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 Hybrid 500 is protected by a 10 year warranty.

Why Buy the Serta iSeries Hybrid 500?

  1. You're a restless sleeper. If you toss and turn in your sleep, 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.
  2. You want the best of memory foam and coils. Can't decide between memory foam and coils? With the Serta iSeries Hybrid 500, you don't have to. You can get the best of cradling, body conforming comfort and resilient support from both!
  3. You want to buy from a US company. All Serta products are designed and manufactured in the US, and have been for the last 85 years. If supporting the US's domestic economy and manufacturing industry is important to you, the Serta iSeries Hybrid 500 is a great choice.

Why Avoid the Serta iSeries Hybrid 500?

  1. You don't like a cushion firm comfort level. The Serta iSeries Hybrid 500 only comes in a cushion firm comfort level, which may be too firm for people who exclusively sleep on their side, or simply not to your liking.
  2. You'd rather a 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.

Final Takeaway

The Serta iSeries Hybrid 500 is a great option if you want cooling, pressure relief, and lumbar support. This mattress is also surprisingly comfortable. You can get the Serta iSeries Hybrid 500 for a great price, today!
