Apex Hybrid

First Impressions

The Glacier Sleep Apex Hybrid is a newcomer trying to undercut the established players on price while matching them on specs. At 14.25 inches thick, it's one of the tallest mattresses we've tested — make sure your fitted sheets can handle the extra height. It arrives compressed and rolled in a box, expanding fully over about 36 hours. The initial off-gassing was mild (noticeably less than the Purple) and cleared within two days.

Glacier has packed this mattress with every cooling technology they could source: copper-infused memory foam, graphite-infused foam, cooling gel, a phase-change cover, and pocketed coils for airflow. On paper, it reads like marketing overload. We were sceptical.

Sleeping on It

The scepticism was partly warranted and partly not. The Apex does sleep cool — genuinely cooler than a standard memory foam hybrid. The initial lie-down sensation is pleasant, and for the first three to four hours of sleep, the combined cooling technologies do their job well. The cover feels cool to the touch, the copper and graphite layers seem to conduct heat away from the body effectively, and the coil base provides meaningful airflow underneath.

However, over a full night, the multiple memory foam layers do what memory foam always does: they retain heat. By the five-to-six-hour mark on warmer nights, we noticed the familiar gradual warming that all foam-heavy mattresses exhibit. It's less severe than a mattress without these cooling treatments, but it's there. The "multi-layer cooling technology" tagline works harder as marketing than as sustained thermal management.

Where the Apex genuinely excels is pressure relief. We scored it among the highest of any mattress we've tested — the combination of responsive memory foam and supportive coils creates a cradling sensation that eliminates pressure points without that "sinking into quicksand" feeling. Edge support is also remarkably strong for a bed-in-a-box product. Sitting on the edge feels stable, and sleeping near the perimeter doesn't create a "roll toward the centre" sensation.

What We Loved

The value. At $1,399 for a queen, the Apex undercuts the Purple Restore Premier by $2,300 and the Tempur-Pedic LuxeBreeze by $3,600 — while delivering comparable pressure relief scores and adequate cooling. The 365-night trial matches Saatva's industry-leading offer, and the lifetime warranty provides long-term confidence. For the money, the Apex over-delivers on comfort and build quality.

What Frustrated Us

The sustained cooling doesn't match the marketing language. "Multi-layer cooling technology" suggests something more transformative than what you get after hour five on a warm night. We'd have preferred honest positioning — "cooler than standard foam" rather than implying all-night active cooling. The mattress is also very heavy (over 100 pounds for a queen), making rotating it a two-person job.

As a newer brand, Glacier doesn't have the long-term reliability data that Tempur-Pedic or Purple can point to. The materials and construction feel solid, but only time will tell whether the cooling treatments maintain their effectiveness over years of use. That's a small leap of faith at any price.

The Verdict

The Glacier Sleep Apex is the best value cooling mattress we've tested. It won't out-cool a Purple Grid or a Tempur-Pedic LuxeBreeze, and it certainly can't compete with active systems like Eight Sleep or ChiliPad. But it delivers genuinely good cooling at a price point that makes its competitors look overpriced. The pressure relief is outstanding, the trial and warranty terms are industry-leading, and the build quality doesn't feel budget. If you want a cooler-sleeping mattress without spending $3,000+, the Apex should be at the top of your shortlist. Just temper your expectations about all-night cooling — it's better than average, not magical.
