Need Help Deciding?
For most sleepers, we recommend the Saatva Rx over the Amerisleep AS5. Our catalog rates it higher for edge support, durability; check current linked-seller prices and terms before deciding on value. The Amerisleep AS5 is the better choice only if you have a strong preference for that brand's specific feel or design.
Amerisleep AS5 vs Saatva Rx: What Actually Differs
The Amerisleep AS5 is a memory foam build, while the Saatva Rx is a hybrid — that construction 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. Their firmness is close but not identical: the Amerisleep AS5 is 3/10 and the Saatva Rx is 3.5/10. Both land near a medium-soft feel, so the half-point difference is less decisive than their construction and pressure response. 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. The linked-seller trial periods aren't symmetrical either: the Saatva Rx is listed with 365 nights at Saatva; no mandatory minimum; $99 return or exchange pickup fee, versus 100 nights at Amerisleep; 30-night minimum; free pickup for the Amerisleep AS5.
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 3/10).
Supportive Plush includes the option closest to a balanced medium feel for back sleepers (vs Soft).
Supportive Plush includes the firmer published option (vs Soft), which may better suit shoppers who prefer more surface support.
Cooling rated the same on both — neither has a heat-management edge in our spec data.
better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weigh most.
Soft includes the softer published option (vs Supportive Plush), which can make contouring easier for lighter sleepers.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
Amerisleep AS5
Strengths
- ✓The five-inch comfort system combines three inches of Bio-Pur with two inches of faster-rebounding Active Flex for deep cushioning without relying on slow memory foam alone
- ✓Two inches of five-zone HIVE foam provide firmer response beneath the head, back, and legs and more give beneath the shoulders and hips according to Amerisleep's construction description
- ✓Choose AS5 Foam over AS5 Hybrid for quieter, steadier contour and the lower current catalog price; choose Hybrid for spring response, support-core airflow, easier movement, and a stronger perimeter
- ✓The solid Bio-Core support layer avoids connected coil movement, a practical construction advantage for couples who prioritize motion isolation over bounce
Considerations
- —The soft 3/10 feel and five inches of comfort foam are a poor starting point for strict stomach sleepers and shoppers who want a flat, firm surface
- —Amerisleep includes heavy sleepers in its broad AS5 positioning but publishes no product capacity or independent compression result on the reviewed page; higher-bodyweight back and stomach sleepers should compare firmer and coil-supported options
- —Amerisleep's seven-degree Refresh comparison, cooling, recovery, circulation, alignment, pressure, pain, motion, edge, and durability statements are manufacturer or construction evidence rather than SleepRanked lab results
Saatva Rx
Strengths
- ✓Deepest plush pressure-relief build in the Saatva line
- ✓Microcoils add close, responsive support
- ✓Graphite and phase-change materials manage heat
- ✓365-night direct-purchase home trial
Considerations
- —Single soft 3-4/10 feel
- —Higher price than Classic
- —Return or exchange pickup carries a $99 processing fee
