Bear | Original Foam

Bear Original Foam Mattress

The Bear Original Foam is an all-foam mattress built for the bodies that actually use it. Gel swirl memory foam sits on top and does the contouring. A responsive comfort layer under it adds bounce and stops the sinking feeling. Six inches of high-density foundation foam carry the structure below that. The feel measures medium-firm, 6.5 to 7 on the firmness scale. Bear backs it with a limited lifetime warranty. It ships free and compressed, GREENGUARD Gold Certified, CertiPUR-US and fiberglass-free.

The cover separates the Bear Original from a basic memory foam build. Celliant fibers absorb body heat and re-emit it as infrared energy at the sleep surface. Beneath it, gel swirl memory foam pulls heat away from pressure points and contours to your shoulders and hips. A responsive comfort layer sits between the memory foam and the base, keeping you from sinking too far. Six inches of high-density foundation foam carry the structure and resist the sagging that pulls older mattresses out of alignment after a couple of years.

Medium-firm is the range that fits most back and side sleepers, and the Bear Original ships compressed in a box from Bear's Arizona facility. Bear ships it free with a 120-night home trial. The Bear Original earned The Strategist's Best in Class for 2025 and made CNET's Best of 2025 list.

The Bear Original Stack

Three systems with three separate jobs.

A good mattress is a sequence of layers, each solving a problem the layer above and below can't. The Bear Original's design is best understood by what each layer is responsible for.

Celliant® Infrared Cover
Mineral-infused fibers woven through the cover fabric absorb body heat and re-emit it as infrared energy. The conversion happens inside the fiber itself, not in a coating applied to the finished fabric.
Infrared | Celliant® Fibers
Adaptive Foam Comfort System
The comfort system runs two foam layers in sequence. Gel swirl memory foam sits on top, where it conforms to your shoulders, hips, and lower back while gel beads draw heat away from the contact zone. A responsive comfort layer underneath adds a slight bounce and prevents that quicksand feeling some memory foam is known for. Together they hold your weight without resisting the small repositioning movements you make through the night.
Pressure Relief | Cooling Gel
High-Density Foundation
Six inches of high-density base foam sit at the bottom of the stack, holding the mattress flat and structurally sound over years of use. Most all-foam mattresses fail right here; cheap base foam compresses unevenly and leaves a body-shaped dent the mattress never recovers from. The foundation is a high-density base foam, and the limited lifetime warranty covers it against manufacturing defects.
High-Density Base | Sag Resistance

What This Mattress Actually Does

What the four layers add up to.

The Celliant cover and the foam stack each contribute different things, and some of what you feel at night comes from the two of them working at once.

Celliant® is a mineral-infused fiber knitted into the cover, where it absorbs body heat and re-emits it as infrared energy at the sleep surface.

Inside the Build

Four layers from top to bottom.

The Bear Original is engineered as a stack, and each layer addresses a different part of how a mattress holds you, cools you, and lasts.

Layer One

Quilted Celliant® Infrared Cover

The top of the Bear Original is a quilted cover woven with Celliant fibers, a textile technology that captures body heat and re-emits it as infrared energy in the 5-20 micron wavelength range. The cover itself is plush, with light quilt foam underneath for surface softness, and the fibers running through it re-emit that energy at the sleep surface.

  • Mineral-infused Celliant® fibers turn body heat into infrared energy
  • Mineral blend infused into the fiber itself, not applied to the fabric
  • Light quilt foam beneath the cover for surface comfort
  • Bear uses this cover across its foam and hybrid mattresses; the Cub, Natural and Trundle use different covers.

Layer Two

Gel Swirl Memory Foam

The first comfort layer is memory foam infused with cooling gel. Memory foam does the contouring, and under load the body sinks into a cradle of its own shape. Conventional memory foam traps heat, and the gel swirl in this layer counters it. Gel beads pull heat out of the high-pressure contact zones at the shoulder, hip and lower back, then spread it sideways through the foam so the surface stays cooler longer. You get the contouring feel of memory foam without paying for it in trapped heat.

  • Shapes to the curve of the shoulder, hip and lower back
  • Gel infusion moves heat out of the contact zone
  • Reduces the "hot pocket" issue common to traditional memory foam
  • Slightly slower response marks the layer where the cradling happens

Layer Three

Responsive Comfort Foam

Most mattresses skip this transition layer, and cheap memory foam beds feel like quicksand without it. In the Bear Original it sits between the slow-recovery memory foam and the high-density base. Its job is two-fold: add a bit of bounce so you can shift positions through the night without fighting the mattress, and prevent your body from sinking deep enough to compress the base layer. It also keeps the medium-firm feel honest, since without this layer the Bear Original would read much softer than 6.5/10.

  • Firmer foam with a slight bounce supports easier repositioning
  • Prevents excessive sinking into the foundation layer
  • Reinforces the medium-firm feel across the comfort system
  • Adds longevity by buffering the base from constant compression

Layer Four

High-Density Foundation Foam

Six inches of high-density foundation foam make up by far the largest single layer in the mattress, and that layer determines whether it is still flat in five years. Budget mattresses give out at the base first; under-spec'd density compresses unevenly and creates body-shaped impressions that never fully recover. This layer is thicker and denser than the comfort foams above it, and the limited lifetime warranty covers it against manufacturing defects.

  • Six inches of high-density base foam form the primary structural layer
  • Holds the mattress flat over years of nightly compression cycles
  • Resists the body-shaped sag that develops in under-spec'd base foam
  • Backed by the Bear Limited Lifetime Warranty

Common Questions

Frequently asked questions.

What comes up before an all-foam mattress goes in the basket.

The Bear Original is an all-foam mattress. The Bear Original Hybrid uses the same foam comfort layers but swaps the high-density foam base for a coil support core. The hybrid feels more responsive (easier to move on), supports more weight before compressing, and breathes better thanks to the airflow between the coils. The all-foam Original has stronger motion isolation (good if a partner moves through the night) and a more close-contouring feel. If you want a more lifted, responsive feel and better airflow, the Hybrid is worth the upgrade.If you want the most contouring memory-foam feel at a lower price, the Original is the choice.
Celliant® is a textile technology: fibers infused with a blend of minerals, woven into the mattress cover. The minerals absorb body heat and re-emit it as infrared energy in the 5-20 micron wavelength range. In practice: the blend is spun into the yarn before the fabric is knitted, so the blend is part of the cover itself, not a finish applied to it, and it stays through washing and years of use.
The Bear Original sits at 6.5 to 7 on a 10-point firmness scale, where 1 is the softest and 10 is firm enough to feel like a hardwood floor. That places it in the medium-firm range, the window that suits back sleepers and most side sleepers. You'll feel the contouring of the memory foam at the surface, but the responsive layer underneath and the high-density base prevent the deep-sink feeling some all-foam beds have. Strict stomach sleepers often want firmer than this; strict side sleepers under 130 lbs sometimes prefer slightly softer. For everyone in the middle, this is the safe firmness range.
A firm, flat, sturdy foundation. Compatible options include a platform bed, a slatted frame with slats spaced less than 5.5 inches apart, a foundation, or an adjustable base. Not compatible: a traditional box spring, or any frame with slats spaced wider than 5.5 inches, since the foam will sag through the gaps over time and can void the warranty. The mattress also works directly on the floor as a temporary setup. If you have an adjustable base, the all-foam construction is fully compatible with bending positions. Only the rolled mattress comes in the carton, so you will need a compatible base or foundation ready before delivery.
You get 120 nights to sleep on the mattress at home. Bear requires a 30-night break-in period before initiating a return, because most foam mattresses feel different in the first couple weeks while the body adjusts and the foam fully decompresses. After night 30 and before night 120, you can email returns@bearmattress.com to start a return. Bear arranges pickup at no cost and issues a full refund. If you keep the mattress past 120 nights, the limited lifetime warranty kicks in for any manufacturing defects in materials or construction.
Bear partners with Truemed, and HSA/FSA eligibility depends on your individual circumstances. Truemed runs the qualification during checkout.
Free FedEx shipping, arriving 2 to 5 business days after the order is placed. The mattress is compressed, vacuum-sealed, and rolled into a box for delivery. Setup is straightforward: position the box where you want the mattress, unroll the mattress on top of your bed base, and cut the plastic packaging. The mattress decompresses to full size within minutes and is sleep-ready within 24 to 48 hours as the foam fully expands. Bear also offers an optional in-home setup and old-mattress removal service at checkout.
Best for: back sleepers, side sleepers, and combination sleepers who want close-contouring memory foam without overheating; people who want a name-brand all-foam mattress at a lower price point than the Bear Pro or Bear Elite; anyone who wants close surface contouring over a base that stays flat. Less ideal for: strict stomach sleepers (who usually want firmer); sleepers who strongly prefer the responsive, lifted feel of an innerspring or hybrid mattress; sleepers heavier than around 230 lbs who want maximum edge support and bounce, where the Original Hybrid is generally a better fit.
Bear mattresses are assembled in the USA from foreign and domestic components, at Bear's facility in Arizona. The mattress is GREENGUARD Gold Certified for low chemical emissions, uses CertiPUR-US® certified foam (verified free of formaldehyde, ozone depleters, prohibited phthalates, mercury, lead, and other heavy metals), and meets federal mattress flammability regulations (16 CFR 1633 and 1632) without using fiberglass.
The Bear Limited Lifetime Warranty covers manufacturing defects in materials and workmanship for as long as you own the mattress. Specifically: defects that cause the mattress fabric to split or crack despite normal use; visible body impressions deeper than 1.5 inches that are not caused by improper foundation; manufacturing flaws in the foam structure. Normal comfort changes over time, damage from improper use, and damage from incompatible foundations are not covered. The warranty requires the mattress be used on a compatible base.
