Apex Hybrid

Design & Build Quality

The Glacier Sleep Apex Hybrid is a 14.25-inch mattress that layers multiple cooling technologies into a substantial, well-constructed package. The build starts with a cooling-infused cover, transitions through copper-infused and graphite-infused foam layers, and rests on a base of individually pocketed coils. The "kitchen sink" approach to cooling materials — copper, graphite, gel, phase-change — reads a bit like marketing overkill on paper, but the resulting mattress genuinely feels cooler than most competitors at initial touch and during the first hours of sleep.

The mattress arrives compressed and rolled, expanding fully within 24-48 hours. At over 14 inches tall, it's one of the thicker options in the cooling mattress category, which means you'll want to ensure your bed frame and sheets can accommodate the height. The cover has a soft, slightly textured hand-feel with a modern aesthetic. Construction quality is consistent throughout — there's no sense of cutting corners in the interior layers, and the coil system provides good structural integrity that should hold up well over the mattress's lifetime.

Cooling Performance

Glacier Sleep has packed virtually every passive cooling technology available into the Apex, and the combined effect is noticeable. The copper-infused memory foam acts as a thermal conductor, drawing heat away from the body. The graphite-infused foam adds thermal regulation properties. Cooling gel in the comfort layer provides additional temperature management. And the pocketed coil base promotes airflow through the mattress core in a way that all-foam designs simply cannot match.

Independent reviewers generally score the Apex between 7.5 and 9.0 out of 10 for cooling — a wide range that reflects varying testing conditions. The consensus is that the Apex sleeps noticeably cool during the initial hours of the night but may begin to warm slightly as the memory foam layers absorb and retain some heat over an extended sleep session. For most sleepers in climate-controlled bedrooms, this is sufficient. For extreme hot sleepers in warm environments, it may not be enough — the same fundamental limitation of all passive cooling solutions applies here.

Pressure Relief & Comfort

The Apex earned a perfect 10 out of 10 for pressure relief in independent lab testing — an exceptional score that reflects the generous memory foam layers working in concert with the supportive coil base. The mattress has a medium to medium-firm feel that accommodates both side sleepers who need cushioning at the shoulders and hips and back sleepers who need structured lumbar support. Sinkage is moderate — you feel cradled rather than perched on top, but you won't feel swallowed by the mattress.

Edge support is remarkably strong at 9.9 out of 10, which is unusual for a mattress with this much foam content. You can sleep right up to the edge without the mattress compressing and threatening to roll you off, and sitting on the edge for getting dressed or tying shoes feels stable and secure. Motion isolation is equally impressive, making the Apex an excellent choice for couples where one partner is a restless sleeper.

Value & Warranty

At $1,399 for a queen, the Glacier Apex Hybrid undercuts most premium cooling mattresses significantly. Compared to the Purple Restore Premier at $3,700 and the Tempur-Pedic LuxeBreeze at $5,000+, the Apex delivers arguably comparable cooling performance and superior pressure relief scores at a fraction of the cost. The 365-night trial period matches Saatva's industry-leading offer, and the lifetime warranty provides long-term confidence. Free shipping and returns eliminate additional financial risk.

Who Should Buy This

The Glacier Sleep Apex is the value champion in the cooling mattress category. If you want multi-layer cooling technology, outstanding pressure relief, and industry-leading trial and warranty terms at a price that doesn't require financing, the Apex belongs at the top of your shortlist. It's particularly well-suited for side sleepers and combination sleepers who need adaptive pressure relief, and for budget-conscious buyers who refuse to compromise on build quality and cooling. The main limitation is that the memory foam layers will eventually retain some heat overnight — if you need active cooling that maintains a set temperature regardless of conditions, you'll need a water-based or air-based system instead. But for the vast majority of warm sleepers looking for their next mattress, the Glacier Apex delivers exceptional performance per dollar.
