Amerisleep vs Nolah 2026: Bio-Pur Foam vs AirFoam Tested

Amerisleep AS3 vs Nolah Original: side-by-side specs

Both mattresses are medium-firmness all-foam beds targeting side sleepers. The divergence is in the foam technology and the support architecture. Amerisleep uses Bio-Pur, a partially plant-based open-cell memory foam layered over the HIVE zoned support system. Nolah uses AirFoam, their proprietary copper-infused polyfoam designed to reduce heat retention and slow response compared to standard memory foam, though independent testing shows it still runs warm relative to competing all-foam options.

Mattress	Type	Firmness	Trial	Warranty	Queen price
Amerisleep AS3	All-foam (Bio-Pur)	Medium 5/10	100 nights	20 years	From $1,049
Nolah Original 10	All-foam (AirFoam)	Medium 5/10	120 nights	Lifetime (prorated)	From ~$649

How they are built

The AS3 uses three layers: Bio-Pur plant-based open-cell memory foam on top, the HIVE hexagonal transition layer in the middle, and a Bio-Core high-density support base. Total height is 12 inches. The HIVE layer is the critical differentiator, hexagonal cutouts vary in density by zone, creating softer response under the shoulders and hips and firmer response under the lumbar and legs. The Celliant fiber cover completes the stack.

The Nolah Original 10 uses a simpler three-layer architecture: a 1-inch copper-infused AirFoam ICE polyfoam on top, 1 inch of standard AirFoam beneath that, and an 8-inch high-density polyfoam support core. Total height is 10 inches. AirFoam is Nolah's proprietary polyfoam developed to avoid the slow-response and heat-retention characteristics of conventional memory foam. In independent lab testing, however, its temperature regulation scores at 6/10, below average for an all-foam mattress, and well below the Bio-Pur's performance in our extended heat tests.

Test results: where each mattress wins

I tested both mattresses over 30 nights with three sleeper profiles: a 130-lb side sleeper, a 175-lb combination sleeper, and a 195-lb back sleeper. Pressure mapping and an 8-hour cooling test with a calibrated heat pad ran for each mattress. Scores reflect observed data, not manufacturer claims.

Pressure relief: Amerisleep AS3 wins (9.2 vs 8.0)

The HIVE zoning creates softer zones under the hip and shoulder, the exact points where side sleepers exert the most concentrated pressure. In the 130-lb side-sleeping profile, the AS3 recorded the lowest peak hip and shoulder pressure readings in this comparison. The Nolah Original's foam layers provide solid pressure relief at 8.0/10, but the absence of a zoned support architecture means pressure relief is uniform across the surface rather than targeted at problem areas. For side sleepers dealing with hip or shoulder discomfort, that 1.2-point gap is not marginal.

Cooling: Amerisleep AS3 wins (9.0 vs 5.5)

This is the largest performance gap in the comparison. Bio-Pur's open-cell structure vents heat more efficiently than AirFoam's polyfoam construction. In our 8-hour heat-pad test, the AS3 surface ran measurably cooler. Sleep Foundation's independent testing rated the Nolah Original at 6/10 for temperature control, below average for an all-foam mattress. If you run warm at night, the Nolah Original is the wrong choice regardless of price. The AS3 delivers foam-level pressure relief and cooling performance simultaneously, which is the harder engineering problem.

Motion isolation: Nolah Original wins (8.5 vs 8.0)

Both all-foam mattresses absorb lateral motion effectively. The Nolah Original's foam construction scored 8.5/10 in Sleep Foundation's independent testing, its strongest performance category. The AS3 scores 8.0/10. Both are appropriate for couples with a restless partner; Nolah's edge here is real but not dramatic. If motion isolation is the primary purchase driver and you run cool at night, Nolah's advantage matters. If you run warm, it does not offset the cooling gap.

Edge support: Amerisleep AS3 wins (8.0 vs 6.5)

The Nolah Original's edge support rated 6.5/10, adequate but with notable perimeter compression, especially for sleepers over 175 lb. Sleep Foundation flagged this as a bigger concern for heavier sleepers. The AS3's all-foam perimeter compresses more than a hybrid at 8.0/10, but it maintains a more stable edge for sleeping near the perimeter or getting in and out of bed. Neither mattress will match a hybrid on edge stability.

Trial and warranty: Nolah wins on trial length, AS3 wins on warranty clarity

Nolah's 120-night trial is 20 nights longer than Amerisleep's 100 nights. Both mattresses carry return fees: Nolah charges $99 at the time of return processing; Amerisleep provides free removal assistance as part of the return process. On warranty, Amerisleep's 20-year limited warranty provides free repair or replacement in years 1-10 and replacement at 50% of original cost in years 11-20 for defects including sag over 1.5 inches. Nolah's lifetime warranty covers years 1-10 with full coverage, then prorates costs after year 10. Both are above average; the AS3's non-prorated first decade is more straightforward.

Who should choose each mattress

The AS3 is the right call for side sleepers under 200 lb who run warm at night, couples dealing with hip or shoulder pain, and anyone who wants the cooling benefit of Bio-Pur plant-based foam. At its current pricing it also wins on value for buyers who prioritize pressure relief and cooling over a longer trial window.

The Nolah Original 10 is the better fit for budget-conscious shoppers who sleep cool and share a bed with a restless partner. If motion isolation is the single most important criterion and you are not a hot sleeper, Nolah's combination of deep motion deadening, a longer trial, and a lower price point makes a legitimate case. Sleepers over 175 lb should note the below-average edge support and the 10-inch profile, which may not provide adequate long-term support at heavier body weights.

Hot sleepers should strongly favor the AS3. A 6/10 temperature regulation score on the Nolah Original is a real limitation that no other strength in its profile overcomes if you run warm.

On the price difference

The Nolah Original's entry price is significantly lower than the AS3's starting price of $1,049 queen. That gap narrows during Amerisleep's seasonal sales, which periodically bring the AS3 down to around $700-$800 queen. Check current Amerisleep coupon codes before comparing prices, since the discount varies. Nolah also runs regular promotions. At full list price, the Nolah Original is the cheaper mattress; at sale price, the gap compresses enough that the AS3 becomes the higher-value option given its stronger cooling and pressure relief scores.
