The Serta iSeries Hybrid series mattresses all incorporate cooling foam layers as well as contouring individually wrapped coils. The iSeries Hybrid mattresses are built for a balance of comfort and support.
The 300 Plush model is the softest of this line, but it is not the softest mattress that Serta offers. That being said, it is still designed for side sleepers or those who prefer a softer mattress.
Will you get the pressure relief you seek on this mattress? Read on for our full overview of this Serta iSeries Hybrid mattress.
You Will Like This Mattress If …
- You are a side sleeper. Soft beds are ideal for people who sleep on their side, as they relieve pressure on shoulders and hips. The 300 Plush features an extra thick layer of EverCool Fuze Gel Memory Foam. This foam is very plush and adds another level of pressure relief.
- You are a hot sleeper. The HyperFeel Surface Design and Cool Reaction Gel Memory Foam are both designed to dissipate heat. In addition, the coil system allows for more airflow. All these elements work together to ensure you won’t be sleeping hot.
- You want a mattress that’s easy to get in and out of. The innerspring components of this mattress make sure it doesn’t collapse as you move toward the edge. Also, there is a layer of foam encasement around the mattress, which further enhances the edge support. You should be able to get in and out of this mattress easily, and you shouldn’t feel like you are going to fall off.
You May Not Like This Mattress If …
- You are a back or stomach sleeper. Back and stomach sleepers often need more support to make sure their spine stays aligned during sleep. This is a soft mattress, so you may require a firmer mattress to give you the proper support on your back or stomach.
- You don’t like a memory foam feel. This mattress contains a layer of Cool Reaction Gel Memory Foam and a layer of EverCool Fuze Gel Memory Foam. If you don’t like the soft, sinking feeling of memory foam, this might not be the best choice for you.
Construction and Materials
The Serta iSeries Hybrid 300 Plush is approximately 13.5” high and contains:
- HyperFeel Surface Design
- 0.5” Cool Reaction Gel Memory Foam
- 2” EverCool Fuze Gel Memory Foam
- 1” Serta Balanced Support Foam
- 886 Pro-Support Coil System with Best Edge Foam Encasement
Feel and Firmness
This mattress is towards the soft end of Serta’s firmness scale; however, it is not the softest mattress they offer.
Most Common Praise: What Makes This Mattress Stand Out?
- Some buyers are happy with the temperature control technology. One wrote that the mattress “keeps you at a comfortable body temperature all night long.”
- Buyers are pleased with Serta’s new HyperFeel Surface Design. “The top has a cotton top which makes it very comfy and soft to sleep on rather than the standard mattress top that is silky and plastic-feeling,” one review says.
- Due to motion transfer control technology, buyers say they aren’t disturbed by their partner or pets moving around in the bed. One wrote, “If you move a lot in your sleep, roll, etc. this is the one for you! We can’t tell when each other are moving around.”
- People find the mattress supportive and comfortable. One reviewer wrote, “I now get a better night sleep and no longer have back and neck pain when I wake up.”
Most Common Complaints And Other Things to Note
- Some buyers found the mattress felt very hard when it arrived, and it took a while to break in and feel comfortable. “When my mattress arrived it was super firm and cold (it was February after all) but within a few hours it softened up,” one person wrote.
- The temperature control technology does not work for everyone. One reviewer explained, “Even though it is supposed to have some cooling gels in the foam it still gets warm, but I wouldn’t say hot. I did find myself rolling over for a cooler spot in the bed.”
- Due to a normal process called “off-gassing,” some reviewers said their brand-new mattresses gave off a chemical smell. This is nothing to worry about, and the odor should go away after a couple of days.
Why Pick This Over Other Serta models?
This model is a soft, cushiony mattress. While it is not the softest in Serta’s full line of mattresses, it is still very plush and a great choice for side sleepers.
This is a hybrid mattress containing both memory foam layers and individually wrapped coils. Other Serta mattresses may be pure memory foam or pure innerspring coil technology, rather than a combination of the two.
This mattress is part of the iSeries Hybrid collection, which means it has the new HyperFeel Surface Design. The website explains this is “a touchably soft cover fabric design that brings the cooling, comforting and supportive feel of memory foam right to the top of the bed.”
The mattress is approximately 13.5” high and contains a HyperFeel Surface Design, 0.5” Cool Reaction Gel Memory Foam, 2” EverCool Fuze Gel Memory Foam, 1” Serta Balanced Support Foam, and 886 Pro-Support Coil System with Best Edge Foam Encasement.
The 300 Plush is the softest of the iSeries Hybrid line and is a good match for hot sleepers, side sleepers, or those who prefer a softer mattress.
