Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS3 over the Tuft & Needle Original Mattress II. Our catalog rates it higher for cooling, motion isolation, pressure relief; check current linked-seller prices and terms before deciding on value. The Tuft & Needle Original Mattress II is the better choice only if you specifically prefer a firmer, more supportive feel.
Amerisleep AS3 vs Tuft & Needle Original Mattress II: What Actually Differs
Both the Amerisleep AS3 and Tuft & Needle Original Mattress II are memory foam mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. Profile-wise they're almost identical — the Amerisleep AS3 measures 12" and the Tuft & Needle Original Mattress II measures 12", so neither will dictate your sheet depth or bed-frame compatibility. The Tuft & Needle Original Mattress II is the firmer of the two at 8/10 (firm), 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 motion isolation: the Amerisleep AS3 rates noticeably higher than the Tuft & Needle Original Mattress II, which is the deciding factor if that dimension is high on your list.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Medium includes the option closest to a balanced medium feel for back sleepers (vs Firm).
Firm includes the firmer published option (vs Medium), which may better suit shoppers who prefer more surface support.
Stronger cooling rating, which matters most for sleepers who run hot or live in warm climates.
better long-term durability — the two specs heavier sleepers should weigh most.
Medium includes the softer published option (vs Firm), 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
Tuft & Needle Original Mattress II
Strengths
- ✓Firm feel aimed at back and stomach sleepers
- ✓Cooling cover plus graphite-and-gel Adaptive foam
- ✓Six standard sizes from Twin through California King
- ✓Fiberglass-free and CertiPUR-US certified
Considerations
- —Firm feel may be less cushioned for some side sleepers
- —All-foam edge support is less reinforced than the hybrid models
- —Shipping fees apply to Hawaii and Alaska
