by In our 30-night head-to-head test, the Amerisleep AS3 wins on cooling, bounce, value, and overall score. The Saatva Loom & Leaf is a strong all-foam premium option with a longer trial and lifetime warranty, but costs $730 more for near-identical pressure relief. Both are all-foam memory mattresses; the AS3 is our pick for most buyers.
Amerisleep AS3
9.2/10
- Bio-Pur plant-based open-cell foam runs measurably cooler than Loom & Leaf gel foam (9.0 vs 8.5/10 in our 8-hour test)
- HIVE 5-zone support targets hip and shoulder pressure without extra foam layers
- ~$730 cheaper than Loom & Leaf at current promotions for near-identical pressure relief
- Better bounce and repositioning ease (6.5 vs 5.5/10) for combination sleepers

Side-by-Side Specs
Both the Saatva Loom & Leaf and Amerisleep AS3 are all-foam memory mattresses at 12 inches. They target the same pressure-relief buyer but differ in foam chemistry, warranty structure, trial length, and price. The Loom & Leaf uses gel-infused memory foam with an organic cotton cover. The AS3 uses Bio-Pur, a partially plant-based open-cell memory foam with HIVE zoned support built into the transition layer.
| Mattress | Type | Firmness | Trial | Warranty | Queen Price |
|---|---|---|---|---|---|
| Amerisleep AS3 | All-foam (Bio-Pur) | Medium 5/10 | 100 nights | 20 years | From $1,049 |
| Saatva Loom & Leaf | All-foam (gel memory) | Relaxed Firm 5.5 / Firm 7 | 365 nights | Lifetime | ~$1,695 (with voucher) |
Construction Breakdown
Saatva Loom & Leaf: Organic Gel Memory Stack
- Cover: Organic cotton with a spun polyester blend that is breathable and chemical-free
- Top comfort: 1" gel-infused memory foam (cooling swirl pattern in Relaxed Firm)
- Pressure relief: 2" gel swirl memory foam or firm memory foam
- Transition: 2" convoluted airflow foam for passive ventilation
- Support: 7" high-density base foam with lumbar zone reinforcement
- Height: 12"
The Loom & Leaf's gel-infused upper layers address heat retention at the foam chemistry level. The convoluted airflow layer creates passive ventilation between the comfort layers and the support base. The lumbar zone in the base foam provides targeted lower-back support. Two firmness options, Relaxed Firm (5.5/10) and Firm (7/10), give buyers a choice the single-option AS3 does not offer.
Amerisleep AS3: Bio-Pur Plant Foam Stack
- Cover: Celliant fiber cover (proprietary, cool-to-touch)
- Top comfort: Bio-Pur partially plant-based open-cell memory foam
- Transition: HIVE zoned support foam, a hexagonal cutout pattern for 5 pressure zones
- Base: Bio-Core high-density support foam
- Height: 12"
Bio-Pur replaces a portion of petroleum-derived chemicals with plant oils, producing a more open-cell structure than conventional memory foam. This means measurably better airflow and a cooler surface in extended testing. The HIVE transition layer uses hexagonal cutouts to create differentiated firmness zones, softer under shoulders and hips, firmer under the lower back and legs, without multiple distinct foam formulations. Ships compressed in a box via standard ground carrier.
The key construction difference: Loom & Leaf uses gel infusion to manage heat; the AS3 uses structural open-cell architecture. Both work, but Bio-Pur measured 1.8°F cooler on average in our 8-hour heat-pad test. See our full AS3 review for deeper individual analysis.
30-Night Test Results
We tested Saatva Loom & Leaf (Relaxed Firm) and Amerisleep AS3 over 30 nights each with three rotating sleeper profiles: side sleeper at 130 lbs, combination sleeper at 175 lbs, and back sleeper at 195 lbs. Pressure mapping in three positions. Cooling measured via calibrated infrared thermometer at 30-minute intervals over 8 hours. Motion isolation via a standardized 10 lb drop test at 24 inches from impact.

Category Head-to-Head
Pressure Relief: Loom & Leaf Edges Ahead (9.3 vs 9.2)
The closest margin in this comparison. Both mattresses scored exceptionally on pressure relief. The Loom & Leaf's gel swirl memory foam closely matches body curves in the side position, particularly at the shoulder and hip. The AS3's HIVE zoned architecture achieves comparable results through structural differentiation rather than foam density variation. In pressure-mapping tests at 130 lbs lateral, the Loom & Leaf recorded marginally lower peak hip pressure. The practical difference between 9.3 and 9.2 is negligible for most sleepers. Both deliver outstanding pressure relief for side sleepers with hip or shoulder discomfort.
The Loom & Leaf's lumbar zone in the base foam provides a modest additional advantage for back sleepers, since it supports the lower back in a way the AS3's HIVE targets from the transition layer rather than the base. See best mattress for painful hips 2026 for how both rank across a broader field.
Cooling: AS3 Wins (9.0 vs 8.5)
The most meaningful performance gap between two all-foam mattresses that both make cooling claims. Bio-Pur's plant-based open-cell structure produces more breathable foam than conventional gel-infused memory foam at equivalent densities. In the 8-hour heat-pad test, the AS3 surface averaged 1.8°F cooler than the Loom & Leaf across the full test period. Gel infusion addresses the symptom of heat retention; Bio-Pur addresses the structural cause by creating more open cell walls for airflow.
For hot sleepers choosing between these two all-foam options, the 0.5-point cooling advantage is real and measurable. The Loom & Leaf's organic cotton cover adds surface breathability that mitigates but does not close the gap. At body weights over 175 lbs, the thermal gap widens as deeper foam compression increases heat transfer.
Motion Isolation: Tie (9.0 vs 9.0)
A genuine tie. All-foam construction absorbs lateral motion at the surface before it propagates through the mattress. In the 10 lb drop test at 24 inches from impact, both mattresses registered equivalent vibration amplitude within measurement error. For couples sharing a bed, either mattress provides excellent motion isolation. This category does not differentiate the two products.
Edge Support: AS3 Leads (8.0 vs 7.8)
Neither all-foam mattress excels at edge support relative to innerspring alternatives, because foam compresses under sustained seated weight at the perimeter. The AS3's 8.0/10 versus the Loom & Leaf's 7.8/10 reflects a modest structural difference in base foam density at the edges. In the seated-edge test at 185 lbs, the AS3 compressed 1.6 inches versus the Loom & Leaf's 1.9 inches. Both fall short of the 9.0+ scores achievable with encased-coil perimeter systems. For buyers who regularly sit on the edge or sleep near the mattress perimeter, neither delivers the edge stability of a hybrid.
Bounce and Responsiveness: AS3 Wins (6.5 vs 5.5)
The Loom & Leaf's 5.5/10 bounce score reflects the traditional slow-response character of dense memory foam. The gel swirl layer does not add responsiveness; it addresses cooling. The AS3's Bio-Pur is more open-cell and less viscous than conventional memory foam, producing a noticeably more responsive feel. Neither mattress suits buyers who want a springy hotel-bed feel, but combination sleepers who change positions at night will find the AS3 meaningfully easier to move on. The 1.0-point gap is real, and Bio-Pur is noticeably quicker to respond than Loom & Leaf's denser gel foam.
Durability and Warranty: Loom & Leaf Wins
Saatva's lifetime warranty has no end date and covers sagging over 0.75 inches. Amerisleep's 20-year AS3 warranty covers sagging over 1.5 inches, a stricter threshold that reflects Amerisleep's confidence in Bio-Pur foam longevity. Both exceed the industry standard of 10 years. For buyers making a decades-long purchase, the Loom & Leaf's lifetime coverage and the 0.75-inch sag threshold is the stronger protection. The 365-night trial versus the AS3's 100-night trial gives Loom & Leaf buyers over a year to evaluate fit, a genuine advantage if you are uncertain about firmness preference.
Value at Current Pricing: AS3 Wins
The AS3 from $1,049 queen delivers five of seven tested categories at a level within 0.2 points of the Loom & Leaf, at significantly lower cost. The Loom & Leaf's advantages in pressure relief, durability and trial length are real but incremental. The AS3 delivers comparable pressure relief, equal motion isolation, and superior cooling and bounce. For buyers who are not making a permanent decades-long purchase commitment, the AS3 is the better value by a wide margin. Check current Amerisleep sale pricing before ordering.

Frequently Asked Questions
Is Loom and Leaf the same as Saatva?
The Loom & Leaf is made by Saatva but is a distinct product line. Saatva's flagship is the Saatva Classic, a luxury coil-on-coil innerspring mattress. The Loom & Leaf is Saatva's all-foam memory mattress with the same lifetime warranty, 365-night trial, and white-glove delivery, but an entirely different construction. It competes directly with other premium all-foam options like the Amerisleep AS3, while the Saatva Classic competes with innerspring and hybrid alternatives.
Is Amerisleep AS3 cooler than Loom and Leaf?
Yes, by a measurable margin. In our 8-hour heat-pad cooling test, the AS3 averaged 1.8°F cooler than the Loom & Leaf (9.0 vs 8.5/10). The difference comes from foam chemistry: Bio-Pur's partially plant-based open-cell structure is structurally more breathable than gel-infused memory foam at equivalent densities. Gel infusion improves on ungelled foam, which is why the Loom & Leaf scores a solid 8.5/10, but it cannot match the airflow of Bio-Pur's open-cell architecture. For hot sleepers choosing between these two all-foam options, the AS3 is the cooler choice.
Which is better for side sleepers, Loom and Leaf or AS3?
Both are outstanding for side sleeping. The Loom & Leaf scored 9.3/10 on pressure relief versus the AS3's 9.2/10, a 0.1-point difference that is negligible in practical use. The Loom & Leaf contours closely to the shoulder and hip through gel swirl memory foam. The AS3's HIVE zoned support creates softer zones under the hip and shoulder through structural differentiation. Both approaches work well. For side sleepers who also sleep hot, the AS3's cooling advantage becomes more important than the marginal pressure gap.
Does the Loom and Leaf have HIVE technology?
No. HIVE is Amerisleep's proprietary 5-zone zoned support system, exclusive to their mattress lineup. The Loom & Leaf achieves pressure differentiation through foam density variation across its comfort layers and a dedicated lumbar zone in the base foam. Amerisleep's HIVE uses hexagonal cutouts in the transition foam to create physically softer and firmer zones without changing foam chemistry. Both deliver high pressure relief scores, but through different engineering approaches.
Is the Loom and Leaf warranty better than Amerisleep?
Yes. The Loom & Leaf carries a lifetime warranty covering sagging over 0.75 inches. The Amerisleep AS3 carries a 20-year warranty covering sagging over 1.5 inches, a stricter threshold. Both are far above the industry standard of 10 years. For buyers planning to keep a mattress for 20-plus years, the Loom & Leaf lifetime warranty and lower sag threshold provide stronger long-term protection. For buyers planning to replace in 10 to 15 years, the 20-year AS3 warranty covers the relevant period adequately.
How does Loom and Leaf compare to AS3 for back pain?
Both mattresses address lower back pain through zone-based support. The Loom & Leaf's base foam includes a dedicated lumbar zone for additional support under the lower back. The AS3's HIVE zoned transition layer provides firmer lumbar support through hex cutout patterns. The Loom & Leaf Relaxed Firm (5.5/10) is slightly firmer than the AS3 Medium (5/10), which benefits back sleepers who need more resistance. The Loom & Leaf also offers a 7/10 Firm option the AS3 does not. See best mattress for lower back pain for broader category guidance.
Is Loom and Leaf or AS3 better for couples?
Both score 9.0/10 on motion isolation, a genuine tie. All-foam construction absorbs lateral motion effectively. The decision then comes down to secondary factors: if one partner sleeps hot, the AS3's cooling advantage is meaningful. If budget is shared, the AS3's lower price is a tangible benefit. For couples where one partner wants a firmer feel, the Loom & Leaf Firm option (7/10) is not available in the AS3 lineup.
Is Loom and Leaf worth the extra cost over Amerisleep AS3?
For most buyers, no. The premium buys you a 0.1-point pressure edge (9.3 vs 9.2), lifetime warranty versus 20-year, a 365-night trial versus 100-night, white-glove delivery, and a second firmness option. What you give up: 0.5 cooling points, 1.0 bounce points, and several hundred dollars. If you are making a multi-decade purchase and the lifetime warranty and 365-night trial have real value to you, the premium is defensible. For most buyers comparing these two mattresses on performance, the AS3 delivers near-equivalent results at lower cost.
Final Verdict
Amerisleep AS3 is the better choice for most buyers in this comparison.
After 30 nights of testing, the AS3 wins four of seven categories (cooling 9.0 vs 8.5, edge support 8.0 vs 7.8, bounce 6.5 vs 5.5, value) and ties motion isolation. The Loom & Leaf wins on pressure relief (9.3 vs 9.2) and durability terms. The pressure gap is 0.1 points, effectively negligible. The durability advantage is real if you intend to keep the mattress for 20-plus years.
Hot sleepers and combination sleepers: AS3 is the clear choice. Bio-Pur runs measurably cooler and repositioning is noticeably easier. The pressure relief gap is too small to override these advantages.
Long-term buyers making a permanent purchase: Loom & Leaf is worth the premium. Lifetime warranty, 365-night trial, and 0.75-inch sag threshold provide meaningfully better long-term protection for a mattress you plan to use for 20-plus years.
Side sleepers on a budget: AS3 from $1,049 queen delivers 9.2/10 pressure relief and 9.0/10 motion isolation, near-Loom-and-Leaf performance at several hundred dollars less. There is no meaningful performance penalty for choosing the AS3.
