After sleeping on the Helix Plus Core mattress for a while, I noticed it balances support with comfort well. It feels medium-firm and adapts to my body without being too stiff or too soft.
The mattress doesn’t come with the cool GlacioTex pillow top by default, but the foam and coils provide solid pressure relief where I need it most. I found it easy to set up since it arrives in a box, which made moving it into my bedroom simple.
The mix of high-density foams and pocketed coils makes the mattress feel durable. It feels a bit heavier than I expected, so adjusting the sheets can be tricky.
Overview of the Plus Core Mattress, California King
After sleeping on this mattress for a few weeks, I found it strikes a good balance between support and comfort. The medium-firm feel helps with pressure points without being too hard.
The coil and foam layers work together to keep me supported through the night. I noticed it sleeps cooler than other foam mattresses I’ve tried.
The cover feels breathable and soft. However, because the mattress is heavier, moving it can be harder.
The size fits well in a larger bedroom and gives plenty of space. I never felt cramped.
What stood out:
- Balanced firmness
- Good pressure relief
- Cooler sleep surface
- Heavier to move
Key Features
After trying the Plus Core mattress, I noticed several things that stood out. The mattress uses materials that support and comfort, while keeping a balance between softness and firmness.
Premium High-Density Foams for Enhanced Comfort
The foams in this mattress feel solid and durable. They give me a steady base to lie on and hug my body just enough without letting me sink in too much.
Over several nights, the support stayed consistent. This is important for long-term comfort.
Targeted Pressure Relief with Medium-Firm Feel
The mattress balances pressure relief and support well. It’s not too soft or too hard, which suits different sleeping positions.
My shoulders and hips felt less pressure, and I didn’t wake up with aches. The medium-firm feel worked for me, but some people might prefer a different firmness.
Cool-to-the-Touch GlacioTex Pillow Top Option
I used the version without the GlacioTex pillow top, but I can see why the cool-to-the-touch upgrade is popular. It helps with heat buildup, which is great for people who get warm while sleeping.
The standard model breathes okay but doesn’t feel as cool as the pillow top version.
CertiPUR-US & GREENGUARD Gold Certifications
The CertiPUR-US and GREENGUARD Gold certifications gave me peace of mind. The foams don’t have harmful chemicals, and the mattress meets strict safety and environmental standards.
I also liked that the mattress doesn’t have fiberglass. This is a plus for people sensitive to irritants or concerned about indoor air quality.
Pros and Cons
After sleeping on this mattress for a while, I noticed clear strengths and a few downsides.
Pros
The support stands out right away. The mattress uses high-density foam that hugs your body without being too soft.
I found the medium-firm feel helpful in keeping pressure off my shoulders and lower back. It’s not too hard, but firm enough to prevent sinking in.
The cooling feature is impressive, especially with the optional pillow top. It kept my side cooler than other mattresses I’ve tried.
The safety certifications gave me peace of mind.
Cons
The mattress doesn’t have much bounce, which might bother those who like a bit of springiness. It feels stable but could be too firm for people who prefer a plush surface.
Since this model doesn’t come with the built-in pillow top by default, it feels less cushioned than I expected. Adding the pillow top upgrade seems necessary if you want extra softness or cooling.
| Pros | Cons |
|---|---|
| Good pressure relief | Lacks bounce for some |
| Medium-firm, supportive feel | Base model less cushioned |
| Cool surface with pillow top | Pillow top upgrade needed |
| Made with safe, quality foam |

Unique Benefits of the California King Size
Using the Cali King size gave me extra length that suited my tall frame perfectly. It’s longer than a standard king, so my feet never hung off the bed.
The width was roomy enough for two people without feeling cramped. The mattress felt supportive but not too hard, and its medium-firm feel helped ease pressure on my shoulders and hips.
I noticed it stayed cool through the night, which made sleeping more comfortable. The larger size can make moving the mattress tricky in tight spaces.
The extra length and balanced support make the Cali King a good choice if you need more room to stretch out.
