Need Help Deciding?
For most sleepers, we recommend the Saatva Rx over the Amerisleep AS5. It scores higher in motion isolation, pressure relief, edge support and delivers stronger overall value. The Amerisleep AS5 is the better choice only if you specifically prefer a softer, more plush feel.
Amerisleep AS5 vs Saatva Rx: What Actually Differs
The Amerisleep AS5 is a memory foam build, while the Saatva Rx is a hybrid — that single difference drives most of the cooling, motion, and feel decisions below. The Saatva Rx stands 15" tall versus 14" for the Amerisleep AS5 — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Saatva Rx is the firmer of the two at 5.5/10 (medium), and the Amerisleep AS5 sits at 3.5/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the Amerisleep AS5 runs $1,849 versus $1,999 for the Saatva Rx — roughly $150 (8%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about. Trial periods aren't symmetrical either: the Saatva Rx ships with a 365-night sleep trial versus 100 nights for the Amerisleep AS5, giving you a longer in-home runway to send it back if the feel doesn't land.
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 3.5/10).
Firmer at 5.5/10 vs 3.5/10 — 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 3.5/10 vs 5.5/10 — 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.
