Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS5 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 AS5 vs Tuft & Needle Original Mattress II: What Actually Differs
Both the Amerisleep AS5 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. The Amerisleep AS5 stands 14" tall versus 12" for the Tuft & Needle Original Mattress II — a 2.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Tuft & Needle Original Mattress II is the firmer of the two at 8/10 (firm), and the Amerisleep AS5 sits at 3/10 (soft) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in motion isolation: the Amerisleep AS5 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.
Firm includes the option closest to a balanced medium feel for back sleepers (vs Soft).
Firm includes the firmer published option (vs Soft), 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.
Soft 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 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
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
