Need Help Deciding?
For most sleepers, we recommend the Big Fig Classic Mattress over the Amerisleep AS3. It scores higher in edge support, durability; decide whether those advantages justify the $900 Queen premium ($2,049 vs $1,149). The Amerisleep AS3 is the better choice only if budget is paramount — it saves roughly $900.
Amerisleep AS3 vs Big Fig Classic Mattress: What Actually Differs
The Amerisleep AS3 is a memory foam build, while the Big Fig Classic Mattress is a hybrid — that construction difference drives most of the cooling, motion, and feel decisions below. Profile-wise they're almost identical — the Amerisleep AS3 measures 12" and the Big Fig Classic Mattress measures 12.5", so neither will dictate your sheet depth or bed-frame compatibility. The Big Fig Classic Mattress is the firmer of the two at 7/10 (medium-firm), and the Amerisleep AS3 sits at 5/10 (medium) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in edge support: the Big Fig Classic Mattress rates noticeably higher than the Amerisleep AS3, which is the deciding factor if that dimension is high on your list. On a Queen, the Amerisleep AS3 runs $1,149 versus $2,049 for the Big Fig Classic Mattress — roughly $900 (44%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Both include a medium-range feel (Medium vs Medium-Firm), so either can work for back sleepers.
Medium-Firm includes the firmer published option (vs Medium), which may better suit shoppers who prefer more surface support.
Cooling rated the same on both — neither has a heat-management edge in our spec data.
better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weigh most.
Medium includes the softer published option (vs Medium-Firm), which can make contouring easier for lighter sleepers.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.

Amerisleep AS3
Strengths
- ✓Three inches of Bio-Pur and two inches of HIVE reverse AS2's 2/3-inch comfort-to-transition ratio, giving AS3 more surface contour while keeping the same 12-inch height and seven-inch Bio-Core base
- ✓The five-zone HIVE cuts provide firmer response beneath the head, back, and legs and more give beneath the shoulders and hips according to Amerisleep's current construction description
- ✓Choose AS3 Foam over AS3 Hybrid for quieter, steadier all-foam contour and the lower current catalog price; choose Hybrid for spring response, support-core airflow, and a stronger perimeter
- ✓The solid-foam support core avoids connected coil movement, a practical construction advantage for couples who prioritize motion isolation over bounce
Considerations
- —Strict stomach sleepers and many sleepers over 230 pounds should compare the medium-firm AS2 or coil-supported AS3 Hybrid before choosing this medium foam design
- —All-foam AS3 has less perimeter reinforcement and through-bed airflow than AS3 Hybrid's eight-inch zoned pocketed-coil core
- —Amerisleep's seven-degree Refresh comparison, cooling, recovery, circulation, alignment, pressure, pain, motion, edge, and durability statements are manufacturer or construction evidence rather than SleepRanked lab results
Big Fig Classic Mattress
Strengths
- ✓Medium-firm balance for back, side, and stomach position changes
- ✓Perforated gel-infused latex and THERMOGEL top add airflow and a cooler first touch
- ✓Three high-density foam layers add more cushioning than Big Fig Firm
- ✓15-gauge pocketed coils, 80 ILD edge foam, and 16 hand-tufted anchors reinforce the support system
Considerations
- —Costs $200 more than Big Fig Firm at regular and current promotional Queen prices
- —Less pillow-top cushioning than Big Fig Luxe
- —Cooling and durability performance descriptions are manufacturer claims rather than SleepRanked lab results
