How the Glacier Original Hybrid Mattress is Made
Glacier uses a combination of signature materials and thoughtful design in their Original Hybrid mattress. Below we share how the mattress is made.
Cooling Quilted Cover
The cooling, breathable cover is made with glacierTECH fibers and ChiroZONE quilting. The fibers are cool to touch, and the breathable fabric allows air circulation and moisture wicking. The quilting provides targeted support to the lumbar area to help with spine alignment. A mattress with extra lower back support is often important to those who want to maintain proper spinal support throughout the night, potentially reducing lower back strain.
Graphite-Infused Zoned Memory Foam
Next, a layer of CarbonICE memory foam is infused with heat-dissipating graphite to help you stay cool. The foam relieves pressure in the joints and is also zoned to provide even more lumbar support and alignment. Getting extra pressure relief and support where needed from the zoned memory foam helps the body maintain proper alignment and may reduce discomfort in sensitive areas, such as the shoulders and hips.
Gel-Infused Memory Foam
Gel-infused memory foam has a responsive feel that provides additional pressure relief. It’s made with ARCFlow ventilated foam, which promotes airflow as it relieves pressure and offers responsive support for body-cradling comfort and support.
Individually Wrapped Coils
Individually encased coils create a responsive, supportive layer. The queen, king, and Cal king size Original Hybrid Mattresses have more than 1000 coils. The coils prevent motion transfer and allow air circulation to regulate mattress temperature. Plus, the perimeter is reinforced with a thicker, double-row of coils of edge support. Extra support, excellent motion control, and high airflow encourage better rest.
Stabilizing Base
Next is the durable base of the Glacier Original Hybrid mattress. It enhances the lifespan of the mattress and creates an overall stable feel. Also, the mattress has handles, making it easier to set up and to move later, if needed, such as if you want to change the bedroom it’s in.
USA Made
This mattress is designed and assembled in the USA. Those who want to support local manufacturing will value this feature when mattress shopping. The Original Hybrid contains domestic and imported materials.
Glacier Original Firmness and Choice of Sizes
The Glacier Original’s medium-firm feel is the company’s most popular firmness level, according to the Glacier website. The company also notes that in surveys, some customers describe the mattress as having a medium feel. The Glacier Original has a firmness rating of 7–8, which puts it in the medium-firm range on a firmness scale of 1–10.
Along with just-right firmness, a mattress must be the right size for your bed. Every mattress size is 12″ thick. Here are the standard US sizes of the Glacier Original Mattress you can choose from:
- Twin: 38” W x 75” L
- Twin XL: 38” W x 80” L
- Full: 54” W x 75” L
- Queen: 60” W x 80” L
- King: 76” W x 80” L
- Cal King: 72” W x 84” L
- Split King: 76” W x 80” L
Glacier’s Original Hybrid mattress is compatible with many standard bed setups. Use alone with a mattress foundation or with a box spring. A standard bed frame requires a foundation or box spring for proper support. A platform bed frame must have a solid surface or slats at least 3 inches wide and less than 3 inches apart. This mattress is also compatible with an adjustable base. If in doubt about compatibility, contact the manufacturer of the foundation, box spring, frame, or base.
Glacier Original Hybrid: Benefits and Any Disadvantages
You may be wondering what it’s like to actually sleep on the Glacier Original Hybrid Mattress. That’s why our team has researched this leading hybrid mattress. Now, we’ll share our opinion on the benefits as well as any disadvantages that we found.
Multiple Comfort and Support Layers
With two layers of memory foam, the Glacier Original Hybrid mattress offers deep pressure relief. The graphite- and gel-infused foam layers contour to your shape and cradle your joints. You may feel like you’re sleeping on a cloud, but you don’t have to worry about sinking into a too-soft surface. The responsive, gel-infused memory foam has enough bounce to allow the foam to spring back after you get up or change position. Plus, the graphite-infused layer offers support for the lower back, so your spine remains aligned.
Speaking of lumbar support, even the quilted mattress cover is targeted to support the lumbar region of the spine. We’re impressed with the combination of a zoned quilted cover and zoned memory foam. You’ll also get plenty of support from the individually wrapped coils. Additionally, the double row of coils along the perimeter of the mattress prevents sagging along the edges. Edge support is crucial for maintaining an evenly comfortable sleep surface and making it easier to get out of bed. We think you’ll like the balance of cushioning and support offered by the multiple memory foam and coil layers.
The targeted support and pressure relief from features like the CarbonICE lumbar zone support layer encourage proper spinal alignment. By providing more support for the lower back and more cushioning under the hips and shoulders, the spine is better able to stay aligned while sleeping. That’s especially true for side sleepers whose hips and shoulders press into the mattress. Extra pressure relief can help prevent tossing and turning at night due to discomfort, which may lead to deeper sleep.
Chiropractor Endorsed
This mattress has received an impressive endorsement for its enhanced lumbar support. It has a Congress of Chiropractic State Association Seal of Approval. The Seal shows it has been evaluated by state chiropractic association members across the US for its value in aligning with chiropractic principles.
Keeps You Cool and Dry
From the breathable, cooling cover to the graphite- and gel-infused memory foam, the Glacier Original Hybrid mattress uses advanced technologies to keep you cool. The cover feels cool to touch, which we think is a nice detail for the layer that’s closest to your skin. The breathable, moisture-wicking material promotes cooling airflow and helps keep you dry so you won’t wake up in an uncomfortable sweat. The refreshing sleep surface, starting from the moment you lie down, can increase comfort and provide relief for those who regularly overheat at night.
Thanks to cutting-edge materials, the CarbonICE and ARCFlow memory foam layers won’t trap heat as they contour to your shape. The graphite-infused foam allows body heat to dissipate, preventing overheating. Unlike many traditional foams, the gel-infused memory foam is breathable and permits cooling airflow. That helps prevent overheating, especially with the advanced cooling tech in the cover.
The layer of coils—more than 1000 in the larger sizes—also helps regulate temperature. Air circulates through the coils and carries heat away from the mattress. If you sleep hot, we believe that you will appreciate the combination of cooling technologies in this mattress. A cool sleep surface can help regulate body temperature, so you stay dry and comfortable, rather than waking up in sweat.
Ideal for Couples
We believe that couples will like the excellent motion isolation features of this mattress. Each coil is individually encased, allowing the coils to move independently. That means that when you move, the coils adapt and prevent the motion from transferring to your partner’s side of the mattress. That makes them much less likely to wake up at night due to your movements (and vice versa) for uninterrupted sleep. Glacier’s Original Hybrid also has perimeter-edge support, which benefits couples with all sleep positions by maximizing the usable sleep space.
Another reason couples may want to consider this mattress is the medium-firm feel. Maybe one of you prefers a softer mattress while the other finds a firmer surface more comfortable. Many couples find that a medium-firm mattress is a great solution when they have different sleep preferences. A medium-firm mattress cushions your body without sacrificing support. It has responsiveness and “push back” support without feeling too firm or overly soft.

Works for Most Sleep Styles
Besides being a great option for couples, the medium-firm feel is suitable for most sleep styles, depending on personal preference. Glacier states on its website that the combination of support and cushioning of the Original Hybrid is best for back sleepers, but it is a comfortable choice for most sleep positions. Side sleepers may find that the mattress offers sufficient pressure relief for the shoulders, hips, and back. Stomach sleepers generally do best with a firm mattress, but some may find that the Glacier Original Hybrid offers enough midsection support.
Fiberglass Free and Eco-Friendly
Glacier’s Original Hybrid has natural fillings. It contains no fiberglass, is made in a fiberglass-free factory, and has no toxic chemicals.
If you prefer to avoid bringing fiberglass into your home, we think you’ll like the fact that this mattress is fiberglass free. Fiberglass is sometimes used as a fire retardant, but Glacier uses alternative materials for safety. Instead of fiberglass, Glacier uses fire retardant yarns and chemical-free rayon in the Original Hybrid. Using a safer alternative for the protective barrier removes issues like skin irritation that can come from exposure to fiberglass, while still meeting fire standards.
This mattress is made with environmentally friendly foams that carry the CertiPUR-US® certification. That means that the foams have passed strict testing and are free of harmful chemicals such as formaldehyde and heavy metals. Foams with this highly regarded certification have low VOCs (volatile organic compounds), making for better indoor air quality. For families with kids and sensitive sleepers, a mattress with fewer potential irritants can bring greater peace of mind.
Other materials in the mattress are also eco-friendly, making for a mattress that is kinder to the environment. For example, the mattress’s base panels are made from REPREVE® recycled polyester. The fiber is made from recycled plastic bottles, diverting them from landfills. Also, the steel coils are recycled from post-consumer steel and tempered for ultra-durability.

Setup is a Snap
Another thing we like about the Glacier Original Hybrid mattress is that it is shipped directly to your door in a box. First, it’s compressed and rolled to fit in a shipping container. Then, when you unbox the mattress, it’s typically easy to set up. When you unroll the mattress, you’ll find the quilted cover face up. All you have to do is lay the mattress on the bed and let it expand to its full thickness. Unlike many foam mattresses, Glacier claims that the Original Hybrid mattress is designed to be odor-free and won’t “off-gas” after unboxing.
Generous Return Policy and Warranty
We’re impressed with Glacier’s generous 365-night sleep trial and lifetime warranty. The sleep trial is much longer than the trial periods of most mattress brands. You get plenty of time to try the mattress at home and arrange for a return and refund if it’s just not working for you. To allow for an initial break-in period, Glacier does not accept returns until 30 days after your mattress is delivered.
If you buy the Glacier Original Hybrid Mattress, you are covered by Glacier’s lifetime limited warranty. We recommend reading the warranty terms, which can change at any time, before purchasing the mattress. Upon approval of the warranty claim, Glacier will replace the Original Hybrid with a brand-new mattress at no cost or provide a discount on your original purchase price, depending on the warranty year. The Glacier warranty covers manufacturing defects, sagging and indentations, and foam deterioration, as explained in the linked terms.
Glacier Original Hybrid Mattress: Final Thoughts
With its double layers of contouring, cooling memory foam and its targeted lumbar support, we recommend including the Glacier Original Hybrid mattress in your search for the best hybrid mattress. The medium-firm feel, and balance of comfort, support, and motion isolation make the mattress an optimal choice for couples and for many sleep styles. We believe that consumers will appreciate the fiberglass-free, eco-friendly materials in the Original Hybrid.
A new hybrid mattress is a major investment. We think that the generous sleep trial and warranty offer peace of mind and help make the purchase decision easier. For all of the above reasons, we believe that the Glacier Original Hybrid Mattress offers value and quality to consumers.
