Be honest. You sometimes fall prey to the marketing jargon mattress brands use to draw you in, with the number one being “advanced cooling technology”. Don’t worry, we do too. But unlike you we get to test it out beforehand so we can tell you whether the juice is worth the squeeze. The Glacier Apex Hybrid promises the very best cooling sleep technology but does it really have it? Read on to find out.
Glacier Apex Hybrid Review and Performance Test Results
Pros

- Excellent motion isolation
- Fiberglass-free
- Offers deep compression and contouring
Cons
- Not suitable for heavier-set stomach sleepers
- Slight off-gassing
Our experience with the Glacier Apex Hybrid Mattress
The Glacier Apex Hybrid wowed me, not with its cooling capabilities (which is its main selling point) but with its motion isolation.
There, I said it.
I have tried many ‘super’ cooling mattresses – and still continue to do so to this day – and the Glacier Apex Hybrid, although somewhat cooling for the first few hours, is not it. It just does not stay cool due to its multiple layers of memory foam.
And that’s not necessarily a bad thing, well, unless you’re someone who tends to sleep extremely hot.
The motion isolation on the Glacier Apex Hybrid however is top notch.
I did not feel any type of movement whatsoever when I tried it out with a partner, and this is (also) due to its memory foam layers. You win some, you lose some I guess but isn’t that life?
Another thing I liked about the Glacier Apex Hybrid is that it provides both compression and contouring which means oodles of pressure relief even if you’re a heavier-set side sleeper.
Firmness
Glacier Sleep describes their Apex Hybrid mattress as a medium-plush, which is around a 4/10 on the mattress firmness scale.
This makes it suitable for strict side sleepers as well as combination sleepers who sleep predominantly on their sides.
A mattress this soft though isn’t suitable for strict stomach sleepers and back sleepers, especially ones who weigh well over 230 lbs since it’ll cause your hips to dip into the mattress, throwing your spinal alignment off balance.
Be forewarned.
Cooling Test
We rate the Glacier Apex Hybrid a 7.5 out of 10 when it comes to temperature regulation.
It’s true that the Glacier Apex Hybrid is filled to the brim with all sorts of actively cooling materials – from a cool-to-the-touch cooling cover to copper– AND graphite-infused foam as well as cooling gel-infused memory foam – but it just lacks that certain something something cooling something.
Sure, you sleep cool for the first few hours but then the memory foam layers win out in the end and start retaining quite a bit of heat.
Motion Transfer Test
We rate the Glacier Apex Hybrid a 9 out of 10 when it comes to motion isolation.
Usually, hybrid mattresses don’t perform well when it comes to absorbing cross-mattress movement, but the Glacier Apex Hybrid’s multiple foam layers do a stellar job at isolating motion transfer.
I did not feel any movement whatsoever when I tried the Glacier Apex Hybrid out with a partner.
Edge Support Test
We rate the Glacier Apex Hybrid a 7 out 10 when it comes to edge support.
The Glacier Apex Hybrid does contain reinforced edge coils and although the edge support on the Apex hybrid isn’t the worst, it isn’t the best either.
You won’t roll off the bed if you sleep close to the edge, but non-stellar level of support will be noticeable if you sit on it.
Pressure Relief Test
We rate the Glacier Apex Hybrid an 8.5 out of 10 when it comes to pressure relief and comfort.
It should come as no surprise that the Glacier Apex Hybrid gets high marks for pressure relief thanks to its multiple layers of proprietary foam and memory foam alternatives.
You get deep compression as well as contouring and targeted support for all areas of the body.
Construction
The Glacier Apex Hybrid mattress contains eight layers. These layers come encased in a proprietary glacierTECH Elite cooling cover that’s breathable and cool to the touch.
The first layer is made up of a quilted pillow top that provides a cushioned and plush feel.
The first foam layer is made up of CarbonICE graphite-infused memory foam that provides pressure relief as well as targeted support.
Below that lies a layer of copper-infused foam that offers responsive comfort as well as better temperature regulation.
Two different layers of responsive memory foam come after that and these layers help provide even more responsive support as well as compression.
The transition layer is made up of ARCFlow ventilated gel foam that’s infused with cooling gel as well as a ventilated design that helps (once again) with cooling as well as pressure relief.
The coil unit of the Glacier Apex Hybrid is made up of individually-pocketed coils that offer zoned and targeted support.
The base layer of the Glacier Apex Hybrid is made up of a high density foam layer that helps provide stability and durability for the entire mattress.
Durability
The Glacier Apex Hybrid appears to be made of good-quality materials that will stand the test of time, especially with proper mattress care and maintenance.

Conclusion
Just because a mattress promises to be extremely cooling does not always mean it is. Although not the worst, the Glacier Apex Hybrid is not the best when it comes to temperature regulation.
What it’s good at is motion isolation as well as pressure relief, and for its price point you’re definitely getting the good end of the bargain.
