Bio-Pur plant foam. HIVE zoned support. Medium 5/10. 100-night trial, 20-year warranty. Best pressure relief: 9.2/10.
Bear Original
Celliant infrared recovery foam. Medium-firm 6/10. 120-night trial, lifetime warranty. Targeted athlete recovery.
Quick Verdict (TL;DR) — Choose by Use Case
Amerisleep AS3 ($1,015 queen at 30% off) and Bear Original ($1,098 queen) share the all-foam category but diverge sharply in philosophy: AS3 prioritizes pressure relief and cooling via Bio-Pur plant foam, while Bear Original prioritizes athlete recovery via Celliant infrared-converting fiber. AS3 wins four of seven tested categories—pressure relief, cooling, motion isolation, and edge support. Bear Original counters with a longer 120-night trial, a lifetime warranty, and the only mattress in this comparison that actively markets to performance athletes. The decision comes down to sleep profile and priority: deep pressure relief for side sleepers (AS3) versus targeted recovery foam for active users (Bear).

Choose Bear Original if you want:
- Celliant infrared-converting fiber for active recovery
- Longer 120-night trial (20 nights more than AS3)
- Lifetime warranty versus AS3’s 20-year coverage
- Medium-firm 6/10 feel better suited to back and stomach sleepers
- Purpose-built athlete and fitness-oriented brand
- Slightly lower MSRP without requiring a sale
What this comparison covers
Side-by-Side Specs
Amerisleep AS3 and Bear Original are both all-foam mattresses, which places them in direct competition for buyers who want foam construction without a hybrid coil layer. Both use proprietary comfort materials—Amerisleep with Bio-Pur plant-based memory foam and HIVE zoned support, Bear with Celliant infrared-converting fiber in the cover and a memory foam comfort layer underneath. The structural similarities make the material-level differences sharper: Bio-Pur versus Celliant is not a minor variation but a fundamental philosophy gap between cooling-optimized pressure relief and performance recovery.

Construction Breakdown
Amerisleep AS3: Bio-Pur All-Foam Stack
- Top: Bio-Pur plant-based memory foam (pressure relief + cooling)
- Transition: HIVE zoned support foam (hex cutout pressure differentiation)
- Base: Bio-Core high-density support foam
- Total height: 12”
- Cover: Soft stretch knit (breathable)
Bio-Pur replaces a portion of petroleum-derived chemicals with plant oils, creating an open-cell foam structure that disperses heat more freely than conventional memory foam. The HIVE cutout pattern in the transition layer is the mechanism behind AS3’s 9.2/10 pressure relief rating: hexagonal cutouts are softer under light-load zones (shoulders, hips) and firmer under heavier zones (lower back, legs). This zoned differentiation requires no physically separated firmness layers—it is built into the geometry of the foam itself. For side sleepers with hip or shoulder pressure, the HIVE architecture directly addresses the problem.
Bear Original: Celliant Recovery Stack
- Top: Graphite memory foam comfort layer
- Transition: Responsive foam transition layer
- Base: High-density support foam
- Total height: 10”
- Cover: Celliant® infrared-converting fiber (recovery claim)
Bear Original’s distinguishing feature is the Celliant cover. Celliant is an FDA-registered general wellness textile that converts body heat into far-infrared energy, which Bear markets as promoting circulation and muscle recovery during sleep. The graphite memory foam underneath adds passive cooling to complement the cover. The construction positions Bear Original firmly in the athlete-recovery niche—the foam stack itself is conventional, but the cover material and the brand’s marketing are oriented toward active users. Whether Celliant’s infrared conversion delivers measurable recovery benefit during a standard sleep session remains brand-supported rather than independently confirmed. What is confirmed: Bear Original at medium-firm 6/10 is better suited to back and stomach sleepers than to dedicated side sleepers.
The construction difference defines the category results below. AS3 leads on pressure relief and cooling through foam chemistry and geometry. Bear Original counters on recovery positioning, trial length, and warranty terms. See our full AS3 review and Amerisleep mattress reviews for individual depth analysis.
30-Night Test Results
MattressNut tested Amerisleep AS3 and Bear Original in our climate-controlled sleep lab over 30 nights each, with three rotating sleeper profiles: side sleeper at 130 lbs, combination sleeper at 175 lbs, and back sleeper at 195 lbs. Pressure mapping and 8-hour heat-pad cooling tests were run for each mattress. Scores reflect observed performance data only—not manufacturer claims.

Category Head-to-Head
Pressure Relief — Amerisleep AS3 Wins (9.2 vs 8.5)
The AS3’s HIVE zoned transition layer is the most direct pressure-relief mechanism in this comparison. The hex cutout pattern creates softer zones under the shoulders and hips—where side sleepers concentrate peak load—and firmer zones under the lower back and legs. In our pressure-mapping tests at 130 lbs in the side position, AS3 recorded the lower peak hip and shoulder pressure readings of the two mattresses. Bear Original’s graphite memory foam provides genuine contouring, and 8.5/10 is a solid result, but the construction is a standard memory foam layer without the geometry-level zoning that drives AS3’s 9.2 score.
For dedicated side sleepers with hip pain or shoulder discomfort, this 0.7-point gap is not small. Bear Original at medium-firm 6/10 pushes back harder than AS3’s medium 5/10, which is the right firmness call for back and stomach sleepers but creates more shoulder pressure for side sleepers at lighter weights. See our full AS3 review for pressure-mapping methodology.
Cooling — Amerisleep AS3 Wins (9.0 vs 8.5)
Bio-Pur’s open-cell structure gives AS3 a genuine thermal advantage over conventional memory foam. In our 8-hour heat-pad test, AS3’s surface averaged cooler than Bear Original throughout the test period. Bear Original’s graphite-infused memory foam layer is designed to draw heat away from the surface—graphite is a known heat conductor—and the Celliant cover converts some body heat to far-infrared energy rather than retaining it as surface warmth. Both mechanisms work, and Bear Original is not a hot mattress at 8.5/10. The gap reflects Bio-Pur’s open-cell structure running cooler at the foam level before any cover contribution is considered.
Hot sleepers will find both mattresses adequate. If cooling is the primary concern and athlete recovery is secondary, AS3 holds the stronger score.
Motion Isolation — Amerisleep AS3 Wins (9.0 vs 8.5)
Both mattresses are all-foam, so both absorb motion well relative to hybrid or innerspring alternatives. The 0.5-point gap between AS3 (9.0) and Bear Original (8.5) reflects the AS3’s foam density and HIVE geometry providing slightly better vibration damping at the impact zone before lateral propagation. In our motion transfer test (10 lb drop, vibration measured 24 inches from impact point), AS3 registered lower vibration amplitude. For couples where one partner is a restless sleeper, AS3’s 9.0/10 is the stronger result. Bear Original’s 8.5/10 is above average and sufficient for most couples, particularly if both partners are relatively still sleepers.
Edge Support — Amerisleep AS3 Wins (8.0 vs 7.5)
Neither all-foam mattress excels at edge support relative to hybrid alternatives with reinforced coil perimeters, but AS3 holds a 0.5-point advantage from its thicker, denser Bio-Core base layer. In our seated-edge test (185 lb load), AS3 compressed less at the perimeter than Bear Original. The difference is practical rather than dramatic—neither mattress collapses under edge load, but AS3’s 12” stack provides more foam depth to resist edge compression than Bear Original’s 10” profile. For buyers who regularly sit on the edge to dress or get up, AS3’s 8.0/10 is the more reliable result in this pair.
Athlete Recovery — Bear Original Wins (Celliant vs Standard Foam)
This category does not carry a numeric score in our lab protocol because Celliant’s infrared recovery benefit cannot be directly quantified by our testing methods. What the data supports: Bear Original is purpose-built and marketed for active users and athletes, with Celliant as an FDA-registered general wellness technology. The claim is that Celliant fibers convert body heat to far-infrared energy, which Bear states promotes circulation and may support muscle recovery during sleep. These claims are brand-supported by Celliant’s clinical studies. Amerisleep AS3 makes no athlete-specific recovery claims; its construction is optimized for pressure relief and cooling, not post-workout recovery.
For athletes prioritizing mattress recovery as part of a training protocol—or buyers who train regularly and want a mattress marketed to that use case—Bear Original is the correct choice in this comparison. See our guide to Amerisleep mattresses for athletes for a broader analysis of recovery-focused foam options.
Durability and Warranty — Bear Original Wins (Lifetime vs 20-Year)
Both mattresses score 9.0/10 on durability in our testing—both use high-density base foam with strong compression-resistance track records. The warranty gap is where Bear Original holds a genuine long-term advantage: a lifetime warranty versus AS3’s 20-year coverage. For a 30-year homeowner buying a mattress intended to last, Bear’s lifetime warranty is a stronger commitment. For a buyer who expects to replace their mattress every 10–12 years regardless, the practical difference between lifetime and 20 years narrows considerably. Amerisleep’s 20-year warranty remains above the 10-year industry standard.
Value at Current Pricing — Amerisleep AS3 Wins (~$1,015 vs $1,098)
At Amerisleep’s current 30% promotional sale, AS3 is approximately $1,015 queen, which undercuts Bear Original’s $1,098 standard pricing by $83. AS3 wins four of seven tracked categories at that price point; Bear wins two (athlete recovery, lifetime warranty). Getting the category leader in pressure relief, cooling, motion isolation, and edge support for $83 less than Bear is AS3’s clearest value case. The caveat: Amerisleep’s 30% sale is periodic, not permanent. At AS3’s full list price ($1,449), Bear Original is $351 cheaper. Check Amerisleep coupon 2026 for current sale status before purchasing.

Frequently Asked Questions
Is Amerisleep AS3 or Bear Original better for side sleepers?
Amerisleep AS3 is the stronger choice for side sleepers. It scored 9.2/10 on pressure relief versus Bear Original’s 8.5/10. AS3’s HIVE zoned transition layer creates softer zones under the hip and shoulder—the pressure points where side sleepers concentrate the most load. Bear Original at medium-firm 6/10 provides more pushback than AS3’s medium 5/10, which suits back and stomach sleepers but increases shoulder and hip pressure for lighter side sleepers. If you sleep primarily on your side, AS3 is the correct recommendation in this comparison.
Is Bear Original actually good for athletes?
Bear Original is specifically built and marketed for athletic and active lifestyle buyers. The Celliant cover is an FDA-registered general wellness textile designed to convert body heat to far-infrared energy, which Bear claims promotes circulation and may support muscle recovery during sleep. The clinical evidence cited is Celliant’s own, and independent studies confirming mattress-level recovery outcomes are limited. What is verifiable: Bear Original is the only mattress in this comparison purpose-built for this use case, and its medium-firm 6/10 firmness suits the back sleeping positions common among athletes. For a broader analysis, see best Amerisleep mattress for athletes 2026.
Which is better for hot sleepers, Amerisleep AS3 or Bear Original?
Amerisleep AS3 holds a clear cooling advantage at 9.0/10 versus Bear Original’s 8.5/10. Bio-Pur plant foam’s open-cell structure dissipates heat more effectively than conventional memory foam—in our 8-hour heat-pad test, AS3 ran measurably cooler across the full test period. Bear Original is not a hot mattress; graphite-infused memory foam and the Celliant cover both contribute to thermal regulation, producing a solid 8.5/10. For hot sleepers for whom cooling is the primary concern, AS3 is the better choice. For hot sleepers who are also athletes prioritizing recovery, Bear Original’s 8.5/10 is sufficient.
What is the difference between Bear Original and Bear Elite?
Bear Original ($1,098 queen) is Bear’s entry-level all-foam mattress with a Celliant cover, graphite memory foam, and medium-firm 6/10 feel. Bear Elite is Bear’s hybrid tier, adding pocket coils for improved edge support, bounce, and airflow at a higher price point. This comparison covers Bear Original specifically. If you are considering the Bear Elite hybrid, the relevant comparison shifts to Amerisleep’s hybrid line—AS3 Hybrid or AS5 Hybrid—rather than the all-foam AS3 evaluated here.
How does Amerisleep AS3 compare to Bear Original for couples?
For couples where motion isolation matters, Amerisleep AS3 is the better choice at 9.0/10 versus Bear Original’s 8.5/10. Both are all-foam mattresses, so both absorb motion well relative to hybrid options. AS3’s 0.5-point advantage reflects its foam density and HIVE geometry providing slightly better vibration damping. If one partner is a restless sleeper or gets up frequently during the night, AS3 damps more disturbance before it reaches the other side. If both partners are still sleepers, the choice shifts to sleep position and recovery priority.
Which has a better warranty, Amerisleep AS3 or Bear Original?
Bear Original carries a lifetime warranty; Amerisleep AS3 carries a 20-year warranty. Bear Original wins on warranty terms. In practice, both exceed the 10-year industry standard by a significant margin, and neither is likely to require warranty replacement within 12 years for average-weight sleepers under normal use. The practical value of a lifetime versus 20-year warranty depends on your expected ownership horizon. For a 25–30 year ownership plan, Bear’s lifetime warranty is the stronger commitment. For a 10–15 year horizon, AS3’s 20-year coverage is more than adequate.
Is Bear Original or Amerisleep AS3 better for back pain?
For back pain, firmness and sleeping position matter more than brand. Bear Original at medium-firm 6/10 provides more pushback and is better suited to back sleepers in the 160–230 lb range, where spinal alignment benefits from a firmer surface. Amerisleep AS3 at medium 5/10 is better for side sleepers with hip or lumbar pressure, where a softer surface reduces peak-pressure loads. Neither mattress is purpose-built for clinical back pain management. If back pain is the primary driver, see our best mattress for back ache 2026 guide for a broader firmness-matched comparison.
Can I try Bear Original before buying?
Bear Original comes with a 120-night in-home trial with free returns. If you are unsatisfied within 120 nights, Bear arranges free pickup and issues a full refund. A minimum break-in period (typically 30 nights) is required before processing a return. Amerisleep AS3 offers a 100-night trial under similar terms. Bear’s 120-night trial gives you 20 additional nights to evaluate the mattress—a meaningful advantage for buyers who take longer to adjust to a new sleep surface.
Is Amerisleep better than Bear for value?
At sale, yes. Amerisleep AS3 at ~$1,015 queen with the 30% off promotion undercuts Bear Original’s $1,098 standard price by $83—and AS3 wins four of seven tracked performance categories. At AS3’s full list price ($1,449), Bear Original is the better value by a significant margin. The Amerisleep sale price changes the calculus entirely: during the sale, you get the higher performer on pressure relief, cooling, and motion isolation for less money. Check Amerisleep coupon 2026 before purchasing to confirm current sale status.
How does Bear Original compare to Saatva Classic?
Bear Original ($1,098 queen, all-foam, 10”) and Saatva Classic ($1,795 queen, luxury coil-on-coil hybrid, 14.5”) are in different tiers. Saatva Classic adds white-glove delivery, a 365-night trial, three firmness options, a lifetime warranty, and hybrid construction that exceeds Bear on edge support, bounce, and weight distribution. Bear Original’s Celliant recovery positioning has no equivalent in the Saatva line. The choice is athlete-recovery focus (Bear) versus luxury hybrid construction with service premium (Saatva). See Amerisleep vs Saatva 2026 for a parallel comparison in the luxury tier.
Final Verdict
AS3 wins four categories; Bear wins two. The tiebreaker is use case, not scores.
After 30 nights testing both mattresses across three sleeper profiles with pressure mapping and cooling data, Amerisleep AS3 wins this comparison on aggregate performance: pressure relief (9.2 vs 8.5), cooling (9.0 vs 8.5), motion isolation (9.0 vs 8.5), and edge support (8.0 vs 7.5). At ~$1,015 with the 30% sale, it also wins on value. Bear Original counters with the only meaningful athlete recovery technology in the comparison (Celliant), a lifetime warranty versus AS3’s 20-year, and a 120-night trial versus AS3’s 100 nights.
Side sleepers, hot sleepers, and couples: Amerisleep AS3 is the correct choice. HIVE zoned foam delivers 9.2/10 pressure relief that outperforms Bear Original’s construction for this profile, at a lower price during active sales.
Athletes and active lifestyle buyers: Bear Original is the purpose-built option. If Celliant recovery technology and an athlete-specific brand matter to your purchase decision, Bear Original delivers that positioning. The medium-firm 6/10 feel also suits the back sleeping position common among athletes during recovery.
Budget-constrained buyers: Bear Original at $1,098 standard pricing is consistently available without requiring a sale. AS3 at sale (~$1,015) is cheaper, but depends on sale timing. If you cannot wait for the Amerisleep promotion, Bear Original is the reliable lower-cost option across all sizes.
