Puffy and Amerisleep are two of the most well-regarded all-foam mattress brands in the direct-to-consumer space. Both offer competitive pricing, long trial periods, and high-quality foam construction. The differences are in foam technology, feel, and which sleeper types each brand optimizes for.
Brand Overviews
Puffy
Puffy launched in 2016 with a focus on pressure relief and a cloud-like sleep experience. The flagship Puffy mattress uses a proprietary "Climate Comfort Foam" that adapts to body temperature. Puffy's line includes: Original Puffy (~$849 queen), Puffy Lux (~$1,399), Puffy Royal (~$1,999), and Puffy Lux Hybrid (~$1,699). Puffy offers a lifetime warranty and 101-night trial.
Amerisleep
Amerisleep was founded in 2010 with a focus on eco-friendly foam materials and zoned spinal support. Their proprietary Bio-Pur foam uses plant-based materials for reduced off-gassing and better breathability. Models range from AS1 (very firm) to AS5 (very plush), allowing true firmness customization. Queen prices range from ~$1,099 (AS1) to ~$1,649 (AS5). Amerisleep offers a 100-night trial and 20-year warranty.
Foam Technology
- Puffy: Climate Comfort Foam (gel-infused memory foam with temperature-adapting properties) + Firm Core Support Foam (high-density base)
- Amerisleep: Bio-Pur foam (plant-based open-cell foam — more breathable than traditional memory foam) + HIVE technology (hexagonal cutouts in transition layer for zoned support) + Bio-Core foam (high-density base)
Feel Comparison
Puffy Original has a classic memory foam feel — slow response, body-contouring, pressure-relieving. It scores very high on pressure relief for side sleepers. Amerisleep's Bio-Pur foam responds faster than traditional memory foam — less of the "sleeping in quicksand" feeling while still contouring. Puffy feels more "cloud-like"; Amerisleep feels more responsive and supportive.
Firmness Options
- Puffy: Single firmness (medium at ~5/10) for Original; Lux and Royal are softer
- Amerisleep: 5 models from AS1 (very firm, 9/10) to AS5 (very plush, 3/10) — full spectrum coverage
Amerisleep wins significantly on firmness customization. If you know your preferred firmness and want to dial it in precisely, Amerisleep's 5-model lineup covers everyone from stomach sleepers (AS1-AS2) to dedicated side sleepers (AS4-AS5). Puffy's lineup is narrower and skewed toward softer feels.
Temperature and Cooling
Both brands address the memory foam heat retention problem with foam engineering. Amerisleep's Bio-Pur open-cell structure provides better airflow than standard closed-cell memory foam. Puffy's Climate Comfort Foam uses gel infusion for cooling. Independent testing generally shows Amerisleep sleeping slightly cooler than Puffy Original, though both are warmer than latex or hybrid alternatives.
Warranty Comparison
- Puffy: Lifetime warranty — covers permanent body impressions over 1.5"
- Amerisleep: 20-year warranty — covers impressions over 0.75" for the first 10 years
Puffy's lifetime warranty is impressive on paper. Amerisleep's 20-year warranty is more aggressive on the impression depth threshold (0.75" vs 1.5") — which is actually more meaningful for day-to-day comfort protection.
Who Should Buy Puffy?
- Side sleepers who want maximum pressure relief
- Those who prefer a classic slow-response memory foam feel
- Sleepers attracted to the "cloud" sleep experience
- Budget-conscious buyers (Original Puffy at ~$849 is competitive)
Who Should Buy Amerisleep?
- Sleepers who know their firmness preference and want to dial it in (5 options)
- Back and stomach sleepers needing firmer support (AS1 or AS2)
- Those who want faster-response foam without sacrificing pressure relief
- Hot sleepers who prefer foam but need better airflow
- Eco-conscious buyers who value plant-based foam materials
Our Pick
For most buyers, Amerisleep AS3 (medium, 5/10) offers the best balance of pressure relief, support, and temperature regulation. Its Bio-Pur foam sleeps cooler than Puffy and its HIVE zoned support is more nuanced. Puffy wins for side sleepers who specifically want the cloud-like slow-response memory foam experience and prefer a budget-friendly entry point.
Frequently Asked Questions
Is Puffy or Amerisleep better for side sleepers?
Both are excellent for side sleepers. Puffy Original provides slightly more contouring pressure relief with its slow-response foam — ideal for side sleepers with significant hip and shoulder pressure needs. Amerisleep AS4 or AS5 provides comparable pressure relief with faster response, which is better for combination sleepers who spend significant time on their side but also switch positions.
Is Amerisleep cooler than Puffy?
Amerisleep's Bio-Pur open-cell foam generally sleeps slightly cooler than Puffy's gel-infused Climate Comfort Foam, based on independent testing. Both are warmer than latex or hybrid alternatives. Neither is ideal for severe hot sleepers — for those cases, a hybrid or latex mattress is recommended over any all-foam option.
Which has a better warranty, Puffy or Amerisleep?
Puffy offers a lifetime warranty; Amerisleep offers 20 years. However, Amerisleep's warranty covers impressions deeper than 0.75 inches (for the first 10 years), while Puffy's covers impressions over 1.5 inches. Amerisleep's threshold is more meaningful for everyday comfort — you'll notice a 0.75-inch sag much more than a 1.5-inch one. Practical protection is comparable.
What is the main difference between Puffy and Amerisleep?
The main difference is feel and customization. Puffy has a classic slow-response memory foam feel — contouring and cloud-like. Amerisleep's Bio-Pur foam responds faster — more supportive and less of the quicksand feeling. Amerisleep also offers 5 firmness levels (AS1–AS5) versus Puffy's narrower lineup, giving buyers more precision in firmness selection.
