It is a Mattress in a Box: What That Means
Glacier’s Summit Hybrid is a mattress in a box, a popular type of affordable mattress available online. It is compressed, packaged, and rolled into a box to conveniently ship to your home within the 48 contiguous US states. As the mattress contains memory foam, it is bendable.
With no special delivery service and no middleman, mattress in a box models incur fewer expenses and pass that savings on to shoppers like you with a lower price tag. When the box arrives, simply unbox the mattress in the bedroom. It typically is easier to get through doorways and hallways than a traditional mattress.
As per Glacier’s US website, its mattresses typically expand within 5 minutes of unboxing. While it expands quickly, giving it a few extra minutes to settle before use can help maximize comfort, their site further explains.
Size Choices
When choosing a mattress, selecting the right size is important. Glacier’s Summit Hybrid Mattress is 13-inches thick and available in many standard US sizes:
- Twin: 38” x 75”
- Twin XL: 38” x 80”
- Full: 53” x 75”
- Queen: 60” x 80”
- King: 76” x 80”
- Cal King: 72” x 84”
Medium Firm
The Summit Hybrid is medium firm, with a 6-7 rating on the mattress firmness scale, as per Glacier’s US site. The industry-wide scale of 1-10 provides a way to describe how the mattress typically feels, with 1 being the softest and 10 the firmest. A medium firm mattress means it does not feel overly soft or extra firm. Many sleepers find medium firm comfortable, although what you prefer is an individual thing.
Handcrafted to Order
This mattress is handcrafted in the USA and made to order. So, when your order is received, craftsmen in New Jersey, Chicago, and Los Angeles begin creating your mattress, explains Glacier’s website. This attention to quality is impressive, in our opinion.
Six-Layer Construction
The 13-inch thick Summit has a hybrid design composed of six layers. At the top is a Cooling Comfort Zoned Pillow Top for support and comfort. The patented ChiroZONE™ quilting offers extra support and durability for the lumbar zone area (lower back).
Cooling and breathability features in the pillow top offer potential benefits; we’ll discuss later in this review how the materials throughout the Summit Hybrid Mattress can benefit some sleepers.
The second layer is the CarbonICE™ lumbar zone support featuring graphite-infused memory foam. Next is 2 inches of CertiPUR-US® gel-infused memory foam layer for responsive support, and beneath it is a breathable ARCFlow™ ventilated gel foam layer.
The fifth layer has two rows of thick, individually-wrapped coils. Finally, a stable base helps prevent the layers above from shifting. That can make for a more durable, longer-lasting construction.
Designed for Comfort for All Sleep Positions
This mattress is designed for use by side, stomach, back, and combination sleepers, as per Glacier’s US site. That means the medium-firm mattress may provide cradling comfort for any sleep style without a sinking feel. With multiple foam layers and coils, the mattress may provide comfort and support for some people.

Glacier Summit Hybrid Mattress Review: Benefits and Any Drawbacks
This hybrid mattress has potential benefits and as with anything else, there are possible limitations for some sleepers. A clearer picture of what to expect can help determine if the Summit Hybrid offers what you want.
Back Support and Pressure Relief
A mattress offering pressure relief and back support can help some people have a comfier sleep. This Glacier mattress has a Congress of Chiropractic State Association Seal of Approval. The esteemed designation means it meets necessary standards to potentially improve spinal health.
The patented ChiroZONE™ quilting is designed to offer extra support in the lumbar zone area. Furthermore, the CarbonICE™ layer helps disperse body weight for pressure relief in this part of the back and encourages the spine’s neutral alignment.
Those who regularly experience painful pressure buildup in the hips, neck, and shoulders after a night of sleep may also benefit from the Glacier Summit’s construction. For example, the thick gel-infused memory foam layer is designed for pressure relief in these specific body areas. It is designed for responsive support, and the ARCFlow™ gel foam layer offers precise body contouring, as can the coils.
Furthermore, the individually-encased coils are able to move individually, potentially providing targeted support and body contouring. When taken together, these features make this mattress one to consider to help prevent body aches. If you have chronic pain, though, we recommend seeing a doctor for custom treatment. This review is not intended as medical advice.
Advanced Cooling and Breathable
Different materials in Glacier’s Summit Mattress are designed for cooling and better breathability, features that hot sleepers and those who want a healthier sleep environment may look for. Good airflow can lead to a drier mattress, more sleep comfort, and better overall bedroom hygiene.
The advanced cooling tech in this mattress impresses us. The CarbonICE™ Lumbar Zone Support helps draw heat from the body, while the ARCFlow™ layer has a ventilated design to allow air to pass easily through it. A mattress with better temperature regulation can make sleeping comfortably easier and potentially lead to deeper slumber.
Cooling fibers in the pillow top layer can wick moisture away from the body, potentially preventing waking up unexpectedly from a deep sleep in a sweat. This top layer also offers a plush sleep surface, with some online reviewers commenting on its soft feel.

Budget-Friendly
The Glacier Summit Hybrid is a good price for a hybrid, especially given its patented sleep technology and thoughtful construction. The mattress in a box style helps explain the lower price. For those who want a new mattress, have a strict budget, and don’t want to compromise on the quality of materials, this Glacier model may be the right fit.
Little Bounce But Good Edge Support
If you are looking for a mattress with a good bounce when you move on it, Glacier’s Summit Hybrid may not be right for you. Some online reviewers point out that it has little bounce, which may not be ideal during intimacy. With that said, other features of the mattress can make being intimate more comfortable. For example, the Summit is made with strong edge support from its thicker coils and breathable design.
Lower Motion Transfer for Couples
Certain web reviewers describe this mattress as having less motion transfer. That often appeals to couples as there’s much less chance of feeling your partner move during the night and waking you up on your side of the mattress. It may help you get an interrupted sleep even if your partner tosses and turns a lot at night.
Fiberglass Free and Eco-Friendly Certifications
The Summit Hybrid Mattress is fiberglass free. There are no toxic chemical flame retardants in it, so there’s no potential fiberglass-related issues like skin and eye irritation. Moreover, it is GREENGUARD® Gold certified, meaning it has been thoroughly tested to meet high standards for low chemical emissions, making it part of a healthier sleep environment.
Also, the foams are CertiPUR-US® certified. They have passed strict tests for certain heavy metals, including mercury and lead, and are free of formaldehyde, ozone depleters, and phthalates. Those looking for a more eco-friendly sleep environment may want this label on their mattress.
No Off-Gassing
There is no odor or off-gassing when unboxing this Glacier mattress, as per the company’s US website. While some memory foam mattresses are made using materials that release potentially harmful VOCs into the air (volatile organic compounds), this mattress does not. That is good news for those who are sensitive to odors and want to make a more eco-friendly choice.
Also Important: Shipping, Sleep Trial and Warranty
The Summit Hybrid ships free across the contiguous 48 US states using ground shipping. Unfortunately, it does not ship to Hawaii or Alaska. A 365-night sleep trial comes with the Glacier Summit Hybrid Mattress, giving you plenty of time to try it at home.
The 365-night trial period extends well beyond a few months, showing the brand’s confidence in its construction. In the unlikely event you want to return the mattress within the allotted time, Glacier offers free returns based on its return policy guidelines.
Glacier also includes a lifetime limited warranty with the Summit Hybrid Mattress. That shows the company stands behind its quality and durable construction. Reading the warranty policy to find out about the included coverage for defects in materials and workmanship, as well as what is excluded and other information, helps you make a more informed decision.
Concluding Glacier’s Summit Hybrid Mattress Review
This hybrid mattress in a box offers potential benefits to a range of sleepers. Although it does not ship to Hawaii or Alaska, the American-made Summit Hybrid offers quality materials while staying budget-friendly. The mattress has the potential to provide relief to some hot sleepers with its cooling tech, and couples may appreciate its low motion transfer.
Plus, the mattress has targeted lumbar zone support that some sleepers look for, especially with its special chiropractor approved label. The medium-firm mattress designed for all sleep positions may also relieve pressure in the hips and shoulders.
Also, eco-conscious shoppers will have more peace of mind with the CertiPUR-US® and GREENGUARD® Gold certifications. The qualities described above lead us to recommend the Glacier Summit Hybrid mattress in a box to certain sleepers for a more comfortable and supportive sleep.
