Need Help Deciding?
For most sleepers, we recommend the Helix Sunset over the Amerisleep AS5. It scores higher in price-to-value and delivers stronger overall value. The Amerisleep AS5 is the better choice only if you sleep hot and cooling is your top priority.
Amerisleep AS5 vs Helix Sunset: What Actually Differs
The Amerisleep AS5 is a memory foam build, while the Helix Sunset is a hybrid — that single difference drives most of the cooling, motion, and feel decisions below. The Amerisleep AS5 stands 14" tall versus 11.5" for the Helix Sunset — a 2.5" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Amerisleep AS5 is the firmer of the two at 4/10 (medium-soft), and the Helix Sunset sits at 2.5/10 (soft) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the Helix Sunset runs $1,099 versus $1,599 for the Amerisleep AS5 — roughly $500 (31%) 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: Helix Sunset at 2.5/10).
Firmness of 4/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 2.5/10).
Firmer at 4/10 vs 2.5/10 — 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 are equivalent — either holds up.
Softer at 2.5/10 vs 4/10 — 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.
