The fundamental distinction between Leesa and Amerisleep lies in their approach to mattress design and target audience. Leesa focuses on creating a universal comfort solution with their single flagship model, while Amerisleep offers five different firmness levels to accommodate diverse sleep preferences.
The Leesa Original features a simpler three-layer all-foam construction measuring 10 inches in height. Its comfort system combines 2 inches of proprietary Avena foam with 2 inches of memory foam, creating a balanced feel that blends bounce with contouring. The 6-inch high-density polyfoam base provides foundational support.
Amerisleep's AS3, their most popular model, stands 12 inches tall with a more complex design. The mattress incorporates 3 inches of plant-based Bio-Pur memory foam, 2 inches of Affinity foam with HIVE technology for zoned support, and 7 inches of Bio-Core support foam. This additional thickness and advanced materials contribute to enhanced pressure relief and durability.

Both mattresses fall within the medium to medium-firm range, but subtle differences affect their overall feel. The Amerisleep AS3 rates at 5 out of 10 on the firmness scale, providing a slightly softer experience. The Leesa Original measures 5.5 out of 10, offering marginally firmer support.
These ratings translate to different sleeping experiences. The AS3 delivers a classic memory foam feel with deeper contouring and body-hugging comfort. Sleepers sink into the mattress more noticeably, experiencing that characteristic memory foam embrace. The Leesa provides a more neutral foam feel, balancing softness with responsiveness for easier movement.
Budget considerations often play a decisive role in mattress selection. The Leesa Original consistently costs $300 to $400 less than the Amerisleep AS3 for comparable sizes. A queen-size Leesa typically retails around $1,000 but frequently drops to $850 or less during promotions.
Amerisleep's AS3 commands a premium price, with queens starting at approximately $1,400. This higher cost reflects additional features including thicker construction, advanced cooling technology, and eco-friendly materials. The investment may prove worthwhile for sleepers prioritizing these enhanced features.

Temperature regulation represents a critical factor for many mattress shoppers, particularly those who sleep hot. Both brands implement distinct cooling strategies with varying effectiveness.
The AS3 incorporates multiple cooling technologies starting with the optional Celliant-infused Refresh Cooling Cover. This innovative fabric converts body heat into infrared energy, promoting better circulation and temperature regulation. Celliant technology has gained FDA recognition for enhancing comfort and sleep quality.
Bio-Pur foam, Amerisleep's proprietary plant-based memory foam, features an open-cell structure that promotes airflow significantly better than traditional memory foam. This design allows heat to dissipate rather than becoming trapped near the sleeping surface. The material contains fewer petrochemicals, reducing off-gassing and creating a more breathable sleep environment.
The Leesa Original employs Avena foam as its primary cooling solution. This latex-alternative material offers better breathability than standard polyfoam while maintaining responsive support. The perforated design enhances airflow throughout the comfort layers.
While effective for moderate temperature regulation, Leesa's cooling capabilities don't match Amerisleep's multi-layered approach. Hot sleepers report more consistent temperature control with the AS3, particularly when equipped with the Celliant cover upgrade.
Couples require mattresses that minimize motion transfer while providing adequate edge support for maximizing usable sleep surface. Both mattresses excel at motion isolation due to their all-foam construction, but performance differences exist.
Memory foam naturally absorbs movement better than other materials, making both options suitable for couples. The Amerisleep AS3's thicker memory foam layer provides superior motion isolation, measuring just 2.11 m/s² in acceleration tests. This exceptional performance ensures partners remain undisturbed by nighttime movements.
Leesa's combination of Avena and memory foam still delivers excellent motion isolation, though slightly less effective than pure memory foam designs. Light sleepers sharing beds with restless partners may notice marginally more motion transfer compared to the AS3.
Understanding how 2 Vs 3 Inch Mattress Toppers affect motion isolation can help couples fine-tune their sleep setup for minimal disturbance.
Edge support often proves challenging for all-foam mattresses. The Leesa Original's 10-inch profile provides decent perimeter support for average-weight individuals. However, heavier sleepers may experience more compression when sitting or sleeping near edges.
Amerisleep's AS3 offers marginally better edge support thanks to its 12-inch thickness and denser support layers. The additional structure helps maintain shape under pressure, though neither mattress matches hybrid or innerspring models for edge performance.
Different sleeping positions require varying levels of support and pressure relief. Understanding how each mattress accommodates these needs helps shoppers choose appropriately.
Side sleeping places significant pressure on shoulders and hips, requiring adequate cushioning for comfort. The Amerisleep AS3's softer feel and thicker comfort layer excel at cradling these pressure points. The 3-inch Bio-Pur layer provides deep contouring that aligns the spine while relieving joint stress.
Leesa's firmer feel may prove less ideal for lighter side sleepers who need more give around pressure points. However, average to heavier side sleepers often find sufficient comfort thanks to the responsive Avena foam layer.
Both mattresses accommodate back sleepers well, providing balanced support for spinal alignment. The Leesa's slightly firmer feel offers excellent lumbar support, preventing excessive sinking in the midsection. This promotes healthy posture throughout the night.
The AS3's HIVE technology creates five distinct support zones, offering targeted firmness where back sleepers need it most. This zoned construction provides softer support for shoulders while maintaining firmer support through the core.
Stomach sleeping requires firmer support to prevent hip sinking and subsequent back strain. Neither mattress proves ideal for dedicated stomach sleepers, though the Leesa's firmer feel offers better support than the AS3.
Stomach sleepers seeking Amerisleep products should consider the firmer AS2 model. Those committed to Leesa may need to explore the Leesa Studio, which provides firmer support at an even lower price point.
While both brands offer hybrid alternatives, understanding when to choose all-foam versus hybrid construction helps narrow options. All-foam mattresses like these models excel at motion isolation, conforming comfort, and quiet operation.
Hybrid mattresses incorporate coil systems that enhance edge support, breathability, and responsiveness. Hot sleepers and those preferring bouncier surfaces often favor hybrids. Both Amerisleep and Leesa offer hybrid versions of their popular models for shoppers seeking these benefits.
The decision between foam and hybrid ultimately depends on personal preference and specific sleep needs. Couples valuing motion isolation typically prefer all-foam, while those prioritizing edge support and cooling choose hybrids.
Long-term protection and risk-free trial periods provide peace of mind for mattress investments. Significant differences exist between these brands' policies.
Both companies offer 100-night sleep trials, allowing customers to test mattresses in their homes. This industry-standard period provides sufficient time to adjust to new sleep surfaces. Both require minimum 30-night adjustment periods before accepting returns.
Return processes remain straightforward for both brands. Customers receive full refunds, and the companies arrange free pickup and donation of returned mattresses. This eliminates disposal concerns for unsatisfied customers.
Warranty terms reveal the most substantial policy difference between brands. Amerisleep provides an impressive 20-year warranty, with full coverage during the first decade. Years 11-20 offer prorated coverage requiring 50% payment for replacements.
Leesa's standard 10-year warranty covers manufacturing defects and excessive sagging. While shorter than Amerisleep's coverage, this non-prorated warranty provides full protection throughout its duration.
Beyond basic construction, both brands incorporate unique technologies enhancing sleep quality. Understanding these features helps justify price differences.
The AS3 showcases multiple proprietary technologies starting with Bio-Pur foam. This partially plant-based material reduces environmental impact while improving breathability and responsiveness compared to traditional memory foam.
HIVE technology represents another Amerisleep exclusive. Hundreds of hexagonal cutouts create targeted support zones, providing variable firmness across the mattress surface. This design cradles pressure points while supporting heavier body areas.
The optional Celliant cover upgrade adds recovery-enhancing properties through infrared technology. Athletes and active individuals particularly value these potential benefits for muscle recovery and circulation improvement.
Leesa emphasizes elegant simplicity over complex features. The Avena foam delivers latex-like responsiveness without natural latex's higher cost or potential allergen concerns. This material provides excellent airflow and quick response to movement.
The seamless cover design features Leesa's signature four-stripe pattern, combining aesthetics with functionality. While lacking advanced technologies, this straightforward approach appeals to shoppers seeking quality without complexity.
Eco-conscious consumers increasingly prioritize sustainable mattress materials. Both brands address these concerns differently.
Amerisleep leads in environmental initiatives through Bio-Pur foam's plant-based content. This reduces petroleum dependence while maintaining performance standards. All Amerisleep foams carry CertiPUR-US certification, ensuring low emissions and absence of harmful chemicals.
Leesa also maintains CertiPUR-US certification for all foams. The company emphasizes social responsibility through mattress donation programs and tree-planting initiatives. While using traditional petroleum-based foams, Leesa ensures responsible manufacturing practices.
Off-gassing concerns affect all foam mattresses initially. Amerisleep's plant-based materials typically produce less noticeable odors. Both brands recommend airing mattresses for 24-48 hours before use to dissipate any lingering smells.
Choosing between Leesa and Amerisleep ultimately depends on individual priorities and circumstances. Consider these key factors when deciding:
