Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS5 over the Saatva Rx. It scores higher in cooling, motion isolation, price-to-value and delivers stronger overall value. The Saatva Rx is the better choice only if you want more time to decide (365-night trial vs 100 nights).
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 4/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in edge support: the Saatva Rx rates noticeably higher than the Amerisleep AS5, which is the deciding factor if that dimension is high on your list. On a Queen, the Amerisleep AS5 runs $1,599 versus $1,999 for the Saatva Rx — roughly $400 (20%) 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?
Both rate the same for pressure relief — choose on firmness instead (side sleepers usually prefer the softer of the two: Amerisleep AS5 at 4/10).
Firmness of 5.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 4/10).
Firmer at 5.5/10 vs 4/10 — 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.
better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weight most.
Softer at 4/10 vs 5.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
