Need Help Deciding?
For most sleepers, we recommend the Big Fig Mattress over the Amerisleep AS3. It scores higher in cooling, edge support, durability and delivers stronger overall value. The Amerisleep AS3 is the better choice only if budget is paramount — it saves roughly $400.
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 — 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 6/10 (medium-firm) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in cooling: the Big Fig 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 $999 versus $1,399 for the Big Fig Mattress — roughly $400 (29%) 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?
Both rate the same for pressure relief — choose on firmness instead (side sleepers usually prefer the softer of the two: Amerisleep AS3 at 6/10).
Firmness of 6/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 7/10).
Firmer at 7/10 vs 6/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Stronger cooling rating, which matters most for sleepers who run hot or live in warm climates.
better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weight most.
Softer at 6/10 vs 7/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Motion isolation rated the same on both — neither has a transfer-disturbance edge.
