The Glacier Apex Euro Pillow Top Hybrid is the model that actually justifies Glacier Sleep as a brand. The Original and Summit are competent cooling hybrids; the Apex is where the engineering gets serious. It’s the only mattress in Glacier’s lineup that uses CopperElement memory foam, it has the glacierTECH Elite cover with roughly twice the cooling fibers of the Original, and at 14 inches tall it offers the full Euro pillow top experience without the $3,000+ price tag that premium memory-foam brands command. This review covers what’s inside the Apex, how it actually performs across the dimensions that matter most for buyers, and whether it’s worth its mid-range pricing relative to the rest of the cooling-mattress market.
- Best for: hot sleepers, side sleepers, premium-feature buyers on a mid-range budget
- Skip if: you’re budget-focused, sleep only on your stomach, or want a foam-only mattress
- Rating: ★★★★★4.7/5
- Price tier: Mid-premium — around $1,599 for a Queen at time of writing
- Why it stands out: Multi-layer cooling stack (cover + copper foam + graphite foam + ventilated foam) is genuinely engineered, not slapped on
What Is the Glacier Apex?
The Apex sits at the top of Glacier’s three-model lineup. Below it: the 12-inch Original Hybrid (entry tier) and the 13-inch Summit Hybrid Pillow Top (mid tier). The Apex is 14 inches tall, built around a hybrid construction (foam comfort layers over a coil base), and finished with a Euro pillow top — which means the pillow top is sewn directly into the cover with no gap underneath, giving it a flusher, more durable look than a traditional pillow top.
Glacier launched in 2024 as the direct-to-consumer brand from Bedding Industries of America, a Los Angeles-headquartered mattress manufacturer with nearly 70 years of production experience. The Apex is made-to-order in BIA’s US factories (Los Angeles, Chicago, and New Jersey) on a 2-to-3 business day production window, then shipped bed-in-a-box style to the customer.
The made-to-order angle is more meaningful than it sounds. Most bed-in-a-box mattresses sit in warehouses for weeks or months before they ship. A made-to-order Apex is freshly assembled, which matters for foam off-gassing and overall freshness on delivery.
Construction and Materials
Top to bottom, here’s what’s inside the Apex:
1. glacierTECH Elite cooling cover. The outermost layer is woven with cooling fibers that pull heat away from the body. The Elite version on the Apex uses approximately twice the cooling fibers of the cover on the Original Hybrid. This is the single most consequential difference between the entry and flagship models in Glacier’s lineup.
2. Euro pillow top (quilted). Sewn directly into the cover with the ChiroZone quilt pattern — extra stitching in the center third of the mattress for added back support where most sleepers concentrate their weight.
3. CopperElement memory foam. The Apex’s signature ingredient. Copper-infused memory foam is heat-conductive — copper genuinely pulls heat away from the body, where standard memory foam tends to trap it. It contours like normal memory foam but runs noticeably cooler.
4. CarbonICE graphite-infused foam. Graphite is another natively conductive material. The CarbonICE layer absorbs body heat from above and redistributes it laterally rather than letting it pool in the foam.
5. ARCFlow ventilated gel foam. A perforated transition foam below the comfort layers. The perforations allow air to move vertically through the mattress as the sleeper shifts, which prevents the foam-bath warmth that all-foam mattresses build up overnight.
6. Individually wrapped recycled-steel coils. Up to 1,056 pocketed coils in the base, made from recycled steel. The pocketed design isolates motion (each coil moves independently) and the coil layer naturally breathes more than any all-foam construction.
7. High-density base layer. Foundation foam that anchors the coils and gives the mattress its structural integrity, plus reinforced edge support around the perimeter for sit-to-stand stability.
The entire build is 100% fiberglass-free, which is a meaningful flag — many cheap cooling mattresses on Amazon use fiberglass as their flame barrier, which can cause serious problems if the cover is ever removed.

How the Apex Performs
Cooling performance
This is the Apex’s headline feature, and it’s the area where Glacier’s spec sheet most aligns with what owners consistently report. The combination of glacierTECH Elite cover + CopperElement foam + CarbonICE foam + ventilated ARCFlow + breathable coil base is the most layered cooling approach in Glacier’s lineup and is genuinely competitive with the cooling-focused models from premium brands at higher price points. Research suggests cooling tech works best when it’s layered across the construction rather than concentrated in one panel, which is exactly what the Apex does.
Pressure relief
CopperElement memory foam contours similarly to standard memory foam — meaning shoulder and hip pressure points get cushioned the way side sleepers need. Combined with the Euro pillow top’s added cushioning, the Apex is one of the better hybrid options for dedicated side sleepers. Back sleepers also benefit from the ChiroZone quilt pattern’s extra center-third support, though the relief is more about contouring than the lumbar-zoned support of orthopedic-style mattresses.
Support and edge stability
Up to 1,056 individually wrapped coils give the Apex serious base support across the entire mattress, not just the center. The reinforced perimeter coils mean edge stability holds up — you can sit on the edge to put on shoes without rolling toward the center, and couples who sleep close to the edge don’t feel like they’re about to fall off. The ChiroZone quilt pattern adds targeted support in the center third where most sleepers concentrate weight.
Motion isolation
Hybrid mattresses naturally trade some motion isolation for the responsiveness that coils provide. The Apex strikes a reasonable middle — the pocketed coil design means motion transfer is more localized than on an old-school innerspring, and the memory foam comfort layers absorb a lot of the smaller movements. Couples and co-sleepers should find the motion isolation acceptable; it’s not best-in-class memory-foam levels, but it’s well above pure-innerspring performance.
Pros and Cons
Pros
- Best cooling in Glacier’s lineup — multi-layer engineering, not single-panel marketing
- CopperElement memory foam is a meaningful upgrade over standard memory foam
- Premium feel at sub-luxury pricing (roughly half the cost of comparable Tempur-Pedic models)
- 100% fiberglass-free across the build
- Lifetime warranty + year-long trial period
- Made-to-order in US factories — fresh delivery, no warehouse aging
- Up to 1,056 individually wrapped coils for support and motion isolation
- Reinforced perimeter for edge stability
Cons
- Highest-priced model in the Glacier lineup
- 14-inch height may not fit all bed frames or fitted sheets
- Newer brand (Glacier launched 2024) means limited multi-year owner data
- Mattress only — Glacier doesn’t sell pillows, sheets, or accessories
- Bed-in-a-box delivery limited to metropolitan US areas
- Pricing/discount cadence still maturing — list prices may not always reflect best deal
Who Should Buy the Glacier Apex
The Apex is the right pick if you are:
- A side sleeper needing pressure relief. The CopperElement memory foam plus Euro pillow top is genuinely designed for shoulder/hip contouring.
- A hot sleeper specifically. If your current mattress runs warm, this is the Glacier model whose cooling stack is most likely to make a difference.
- Part of a couple wanting motion isolation. The pocketed coil construction and memory-foam comfort layers handle motion better than most hybrid alternatives.
- A premium buyer open to newer brands. If you’d otherwise be cross-shopping Tempur-Pedic Breeze or Saatva Solaire and balking at $3,000+ Queen prices, the Apex offers a competitive build at roughly half that.
Skip the Apex if you’re strictly budget-focused (the Original Hybrid is the right Glacier model), sleep only on your stomach (a firmer all-foam or innerspring will support you better), or want a foam-only mattress without coils.
Pricing, Trial, and Warranty
Pricing. The Glacier Apex Queen sits at around $1,599 at time of writing, often discounted from a higher list price during Glacier’s promotional cycles. Twin XL, Full, King, and Cal King are priced proportionally. For the most current pricing, check Glacier’s site directly via the CTA buttons in this review.
Trial period. Glacier offers a year-long sleep trial across its lineup — significantly longer than the industry standard 100-night trial that most DTC brands run. A full year is enough time to experience the mattress across season changes, which is when a lot of cooling/warming complaints actually surface.
Warranty. Lifetime warranty on every mattress in the Glacier lineup. Cover bodily indentations beyond standard wear, structural failures, and manufacturing defects.
Shipping and delivery. Free shipping. Made-to-order production runs 2-3 business days before shipping. Bed-in-a-box delivery to metropolitan US areas; check Glacier’s site for current zone coverage.
Frequently Asked Questions
How does the Apex compare to the Original and Summit?
The Original (12″) is the entry-tier cooling hybrid. The Summit (13″) adds a pillow-top layer and slightly upgraded cooling cover. The Apex (14″) is the only model with CopperElement memory foam and the glacierTECH Elite cover with 2x cooling fibers — and the only model worth recommending specifically to genuinely hot sleepers.
Is the Apex worth the upgrade over the Summit?
It depends on what you need. If cooling is your top priority and you’re a side sleeper or hot sleeper, yes — the Apex is the upgrade that justifies itself. If you’re a back sleeper who runs cool and just wants extra cushioning, the Summit at $400 less is the better value pick.
Does the Apex actually sleep cool, or is that marketing?
Real cooling comes from layering, not single materials. The Apex stacks four heat-conductive elements (cooling cover fibers, copper-infused foam, graphite-infused foam, ventilated transition foam) over a naturally breathable coil base. That’s genuine engineering, not a single PCM panel marketed as “cooling.” Owners who specifically chose the Apex for cooling tend to report it delivers on the promise.
How long will the Apex last?
Glacier offers a lifetime warranty against structural defects and bodily indentations beyond normal wear. Realistically, a well-built hybrid like the Apex should last 7-10+ years before noticeable comfort degradation, with the coil base typically outlasting the foam comfort layers. The lifetime warranty covers manufacturing-grade failures across that span.
Final Verdict
The Glacier Apex is the strongest case Glacier Sleep can make for itself as a brand. The CopperElement foam, multi-layer cooling stack, fiberglass-free build, and lifetime warranty are all things that genuinely matter to mattress shoppers, and the made-in-USA construction backs up the marketing. The trade-off is the lack of a decade-long customer-review track record, but with a year-long trial, that risk is essentially refundable. If you’re a hot sleeper or side sleeper looking at premium cooling hybrids and don’t want to spend $3,000+ on the Tempur-Pedic equivalent, the Apex is one of the more credible alternatives currently on the market.
14-inch premium cooling hybrid with CopperElement memory foam, glacierTECH Elite cover (2x cooling fibers), and up to 1,056 recycled-steel coils. Year-long trial, lifetime warranty, made-to-order in the US.
