Need Help Deciding?
For most sleepers, we recommend the Big Fig Mattress over the Amerisleep AS3. It scores higher in cooling, motion isolation, pressure relief and delivers stronger overall value. The Amerisleep AS3 is the better choice only if you have a strong preference for that brand's specific feel or design.
Amerisleep AS3 vs Big Fig Mattress: What Actually Differs
The Amerisleep AS3 is a memory foam build, while the Big Fig Mattress is a hybrid (plant-based_memory_foam vs innerspring-hybrid) — that single difference drives most of the cooling, motion, and feel decisions below. The Big Fig Mattress stands 13" tall versus 12" for the Amerisleep AS3 — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Big Fig Mattress is the firmer of the two at 7/10 (medium-firm), and the Amerisleep AS3 sits at 5.5/10 (medium) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the Big Fig Mattress runs $1,399 versus $1,749 for the Amerisleep AS3 — roughly $350 (20%) 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?
Pressure-relief data not available for one or both mattresses — spec not available.
Firmness of 5.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 7/10).
Firmer at 7/10 vs 5.5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Cooling rating not available for one or both mattresses — spec not available.
Durability and edge-support ratings not available — spec not available.
Softer at 5.5/10 vs 7/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Motion-isolation data not available for one or both mattresses — spec not available.
