by Amerisleep AS3
The AS3 is our top pick in the Amerisleep vs Tempur-Pedic matchup. At roughly half the price of the TEMPUR-Cloud, it delivers near-identical motion isolation, superior cooling from open-cell Bio-Pur foam, and a 20-year warranty — double Tempur-Pedic’s coverage. In our 2026 testing cycle it scored 9.2 overall versus 7.9 for the TEMPUR-Cloud.
Medium 5/10 firmness
100-night trial
20-year warranty
The Amerisleep AS3 is our top pick in this matchup: it costs roughly half the price of Tempur-Pedic's entry model, runs cooler in our surface tests, and ships with a 20-year warranty versus Tempur-Pedic's 10. The Tempur-Pedic TEMPUR-Cloud earns a spot for strict side sleepers who want the deepest slow-response contouring and plan to keep a mattress for a decade or more at heavier body weights.
Amerisleep AS3
9.2/10
- Near-perfect motion isolation in our rolling-pin test, imperceptible to a sleeping partner
- HIVE 5-zone zoned support keeps the lumbar in line for back and side sleepers
- Partially plant-based Bio-Pur foam, open-cell construction for breathability, CertiPUR-US certified
- 20-year warranty, double Tempur-Pedic's coverage at roughly half the price
- Cooler surface in our 30-minute heating-pad tests versus the TEMPUR-Cloud
- Softer edge support than hybrids or denser foam options
- Less dense than TEMPUR material, so heavier sleepers over 220 lb may see earlier wear over 10-plus years
For most shoppers comparing Amerisleep with Tempur-Pedic, the AS3 wins on value. You get nearly identical motion isolation at half the price, better cooling, and a longer warranty. In our 2026 testing cycle it scored 9.2 overall versus 7.9 for the TEMPUR-Cloud.

Amerisleep vs Tempur-Pedic: who should buy which
The AS3 is the right call if you share a bed and one person is a light sleeper. Motion isolation is the most meaningful metric for couples, and the AS3 delivers near-perfect scores in our testing using a rolling-pin drop protocol at 14 inches from impact. Both mattresses are excellent isolators, but the AS3 costs roughly $950 less at queen size, and that gap alone decides most comparisons.
Tempur-Pedic justifies its price on foam density and long-term durability. TEMPUR material runs around 4 lb per cubic foot, which resists body impressions longer than most plant-based foams, particularly for sleepers over 200 lb who keep a mattress for 10 or more years. If that describes your situation, the durability advantage is real and the premium makes sense.
Cooling is where the AS3 pulls ahead clearly. Its open-cell Bio-Pur foam shed heat faster than the TEMPUR-Cloud in our 30-minute heating-pad surface tests. Dense TEMPUR material traps body heat, which is the most common long-term complaint in owner reviews. Hot sleepers should weigh that difference seriously.
Firmness and feel
The AS3 measures 5/10 on our firmness scale, medium range, suitable for side and back sleepers under 220 lb. The TEMPUR-Cloud measures around 6/10, with the distinctive initial softness that firms progressively as the material responds to body heat. That slow-response feel is Tempur-Pedic's signature; some sleepers love it, others find it makes repositioning feel sluggish.
For back sleepers, the AS3's HIVE zoned layer keeps the lumbar supported without pressing into the lower back. The TEMPUR-Cloud holds the spine in alignment through deep, even contouring. In our back-sleep position tests, lumbar support scores were close: 8.9 for the AS3 versus 8.6 for the TEMPUR-Cloud.
Strict side sleepers with hip sensitivity may genuinely prefer the TEMPUR-Cloud. Its denser foam distributes weight over a larger surface area, reducing peak pressure at the hip point. Our pressure-mat readings scored it 9.0 for hip pressure relief versus 8.9 for the AS3, marginal but real.
Our picks in this comparison
Tempur-Pedic TEMPUR-Cloud
7.9/10
- Best-in-class pressure relief (9.0/10), no notable pressure points across sleep positions
- Proprietary TEMPUR foam resists impressions longer, better long-term durability for heavy sleepers
- Classic deep-contouring slow-response feel, quiet with zero motion transfer
- Made in USA (Duffield, VA)
- $1,999 queen, roughly double the price of the AS3
- Dense foam traps more heat than the open-cell AS3 in our tests
- Very slow response time; some sleepers feel stuck when repositioning
- $175 return fee during the 90-night trial
- 10-year warranty versus Amerisleep's 20-year coverage
The TEMPUR-Cloud earns its spot for strict side sleepers who want the deepest possible contouring and for heavier sleepers who need a mattress built to last 10-plus years. For most other buyers, the value gap against the AS3 is difficult to justify.
Saatva Classic
9.1/10
- Best cooling in this comparison, dual-coil airflow that neither all-foam model can match
- Exceptional edge support, one of the strongest we test among any mattress category
- Free white-glove delivery with in-room setup and old mattress removal
- 365-night trial and a lifetime warranty, the longest of any option in this comparison
- Three firmness options: Plush Soft, Luxury Firm, and Firm
- Moderate motion isolation due to coil bounce, not ideal for very light sleepers
- Heavy and not compressible, delivery only, not compressed in a box
- $99 return fee applies during the trial
If all-foam feels too warm or too body-hugging, the Saatva Classic is the natural alternative in this price range. At 9.1 overall it actually scores higher than the TEMPUR-Cloud in our lab, and the 365-night trial is the longest of any mattress in this comparison.
Motion isolation: the key metric for couples
Both mattresses isolate motion well. In our rolling-pin drop protocol, the AS3 registered at the low end of our scale and the TEMPUR-Cloud came in just slightly behind, and both sit well below the threshold where disturbance wakes a sleeping partner. The difference in practice is negligible. If motion isolation is your only reason to compare these two, choose the AS3 on value.
Price and long-term value
Amerisleep runs frequent promotions. The AS3 queen stays consistently in the $949 to $1,099 range during active sales. Tempur-Pedic holds pricing more firmly, with the TEMPUR-Cloud queen at $1,999 and modest discounts during sale events. Over a 10-year ownership period at queen size, that gap is roughly $950 upfront.
Durability partially closes the gap. TEMPUR material at around 4 PCF density resists sagging longer than lighter plant-based foams, particularly for sleepers over 200 lb who keep a mattress for 10 or more years. Below 200 lb and under 8 years of planned ownership, the AS3 wins on value without question.
Cooling: Amerisleep wins clearly
Dense TEMPUR material is the main reason Tempur-Pedic owners complain about sleeping hot. The foam traps body heat at the contact surface. In our 30-minute heating-pad surface tests, the TEMPUR-Cloud ran 2.3°F above ambient. The AS3 came in at 1.4°F above ambient. That's a consistent gap across multiple test runs, not a fluke.
The AS3's open-cell Bio-Pur construction lets air move through the material. It won't match the airflow of a coil hybrid, but for an all-foam mattress it's among the more breathable options we test. Hot sleepers choosing between these two brands should weight this difference heavily.
Warranty and trial: Amerisleep wins both
Amerisleep's 20-year warranty splits into two decades: years 1 through 10 cover repair or full replacement for manufacturing defects and sagging over 1.5 inches at no charge. Years 11 through 20 provide a 50% replacement discount. For a mattress with a practical lifespan of 10 to 15 years, the Amerisleep warranty covers the full useful life.
The TEMPUR-Cloud comes with a 10-year warranty. The trial is 90 nights with a $175 return fee. The AS3 is 100 nights with free returns. On every single policy metric, Amerisleep comes out ahead.
Long-term durability: where Tempur-Pedic makes the case
TEMPUR material at around 4 PCF density resists body impressions over time better than lighter foams, particularly for sleepers over 200 lb. Over a 10-year-plus ownership window, the denser foam maintains its shape more consistently. That's the one area where Tempur-Pedic's premium is doing real work rather than paying for brand marketing. If you're over 200 lb and planning to keep the mattress for 12 or more years, the durability argument is legitimate.
For sleepers under 200 lb and those replacing on a 7-to-10-year cycle, the durability gap closes considerably. The AS3's 20-year warranty covers sagging impressions over 1.5 inches, so if wear occurs at that level before year 10, Amerisleep replaces it free.
For value, cooling, and warranty length, the Amerisleep AS3 wins this comparison on a 100-night trial. The TEMPUR-Cloud suits strict side sleepers and heavy long-term owners who need dense foam durability. The Saatva Classic is the alternative for anyone who wants coil airflow and the longest trial in this comparison.
The honest verdict
Buy the Amerisleep AS3 if you want the best motion isolation per dollar, run hot at night, or care about partially plant-based materials. It out-cools the TEMPUR-Cloud in our tests and comes with a 20-year warranty at roughly half the price. For most couples comparing these two brands, the AS3 is the cleaner decision.
Buy the TEMPUR-Cloud if you weigh over 220 lb and plan to keep a mattress for a decade, or if you genuinely need the deepest possible slow-response contouring for hip or shoulder pain. Dense TEMPUR foam provides durability that lighter foams cannot match at the same price point over the long run.
If foam as a category does not feel right, the Saatva Classic adds coil airflow, a 365-night trial, and stronger edge support, the best non-foam alternative in this comparison.

Frequently asked questions
Is Amerisleep as good as Tempur-Pedic?
In our 2026 lab testing, the Amerisleep AS3 scored 9.2 overall versus 7.9 for the TEMPUR-Cloud. The AS3 wins on cooling, warranty length, and value per dollar. The TEMPUR-Cloud scores better on long-term durability for heavier sleepers and on depth of contouring for strict side sleepers. For most shoppers, the AS3 represents better value.
What is the main difference between Amerisleep and Tempur-Pedic foam?
Amerisleep uses a partially plant-based Bio-Pur foam with an open-cell structure that breathes better. Tempur-Pedic uses proprietary TEMPUR material at around 4 PCF density, which contours more deeply and lasts longer under heavy use. The trade-off is that TEMPUR foam runs warmer and has a slow response time that some sleepers find uncomfortable when repositioning.
Does Tempur-Pedic have a better warranty than Amerisleep?
No. Amerisleep offers a 20-year warranty: full replacement years 1 through 10, a 50% discount on replacement years 11 through 20. Tempur-Pedic's TEMPUR-Cloud covers 10 years. Amerisleep also offers a 100-night trial with free returns, versus Tempur-Pedic's 90 nights with a $175 return fee.
Which is better for hot sleepers?
The Amerisleep AS3. Its open-cell Bio-Pur foam allows air to move through the material, producing a cooler surface in our testing. Dense TEMPUR material traps body heat more, which is the most common long-term complaint from Tempur-Pedic owners. For the best cooling of all three options, the Saatva Classic's dual-coil construction outperforms both foam models.
