Need Help Deciding?
For most sleepers, we recommend the Avocado Vegan Mattress - Medium over the Amerisleep AS3. Our catalog rates it higher for edge support, durability; check current linked-seller prices and terms before deciding on value. The Amerisleep AS3 is the better choice only if you have a strong preference for that brand's specific feel or design.
Amerisleep AS3 vs Avocado Vegan Mattress - Medium: What Actually Differs
The Amerisleep AS3 is a memory foam build, while the Avocado Vegan Mattress - Medium is a hybrid — that construction difference drives most of the cooling, motion, and feel decisions below. The Amerisleep AS3 stands 12" tall versus 11" for the Avocado Vegan Mattress - Medium — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Avocado Vegan Mattress - Medium is the firmer of the two at 6/10 (medium), and the Amerisleep AS3 sits at 5/10 (medium) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in long-term durability: the Avocado Vegan Mattress - Medium rates noticeably higher than the Amerisleep AS3, which is the deciding factor if that dimension is high on your list. The linked-seller trial periods aren't symmetrical either: the Avocado Vegan Mattress - Medium is listed with 1-year trial at Avocado; 30-night minimum; $99 return fee, versus 100 nights at Amerisleep; 30-night minimum; free pickup for the Amerisleep AS3.
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 5/10).
Medium includes the option closest to a balanced medium feel for back sleepers (vs Medium).
Medium includes the firmer published option (vs Medium), 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.
Medium includes the softer published option (vs Medium), 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 AS3
Strengths
- ✓Three inches of Bio-Pur and two inches of HIVE reverse AS2's 2/3-inch comfort-to-transition ratio, giving AS3 more surface contour while keeping the same 12-inch height and seven-inch Bio-Core base
- ✓The five-zone HIVE cuts provide firmer response beneath the head, back, and legs and more give beneath the shoulders and hips according to Amerisleep's current construction description
- ✓Choose AS3 Foam over AS3 Hybrid for quieter, steadier all-foam contour and the lower current catalog price; choose Hybrid for spring response, support-core airflow, and a stronger perimeter
- ✓The solid-foam support core avoids connected coil movement, a practical construction advantage for couples who prioritize motion isolation over bounce
Considerations
- —Strict stomach sleepers and many sleepers over 230 pounds should compare the medium-firm AS2 or coil-supported AS3 Hybrid before choosing this medium foam design
- —All-foam AS3 has less perimeter reinforcement and through-bed airflow than AS3 Hybrid's eight-inch zoned pocketed-coil core
- —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
Avocado Vegan Mattress - Medium
Strengths
- ✓The wool-free build substitutes organic cotton batting and carries Vegan Action and PETA approval, giving animal-material-avoidant shoppers a specific alternative to the Green line
- ✓Three inches of organic Dunlop latex create a buoyant medium surface for back, stomach, and combination sleepers without the slow sink of memory foam
- ✓The current support family uses up to 1,379 individually wrapped coils and three wire gauges across seven zones to tune the perimeter and ergonomic support
- ✓Medium delivers the core vegan material package without Plush's added two inches of latex, taller profile, and price premium
Considerations
- —Side sleepers who need deeper shoulder and hip cushioning should compare Vegan Plush instead of assuming the shared materials create the same feel
- —Wool-free does not mean foam-free or spring-free; this model still uses Dunlop latex over a pocket-coil support unit
- —The 118-pound Queen is heavier than Green Medium and can require two people for setup or rotation
