Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS3 over the Tuft & Needle Mint Mattress II. Our catalog rates it higher for motion isolation; check current linked-seller prices and terms before deciding on value. The Tuft & Needle Mint Mattress II is the better choice only if you specifically prefer a firmer, more supportive feel.
Amerisleep AS3 vs Tuft & Needle Mint Mattress II: What Actually Differs
Both the Amerisleep AS3 and Tuft & Needle Mint Mattress II are memory foam mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. The Tuft & Needle Mint Mattress II stands 13.5" tall versus 12" for the Amerisleep AS3 — a 1.5" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Tuft & Needle Mint Mattress II is the firmer of the two at 7/10 (medium-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 Mint Mattress II, which is the deciding factor if that dimension is high on your list.
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).
Both include a medium-range feel (Medium vs Medium-Firm), so either can work for back sleepers.
Medium-Firm 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 — the two specs heavier sleepers should weigh most.
Medium includes the softer published option (vs Medium-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 Mint Mattress II
Strengths
- ✓Gel Memory Foam adds contouring pressure relief
- ✓Medium-firm feel designed for all sleeping positions
- ✓Cooling cover plus graphite-and-gel Adaptive foam
- ✓Six standard sizes from Twin through California King
Considerations
- —All-foam edge support is less reinforced than the hybrid models
- —Costs more than the Original II
- —Shipping fees apply to Hawaii and Alaska
