How We Test Mattresses
Our reviews are based on firsthand, hands-on testing and real-world sleep experience. We evaluate mattresses using consistent criteria, including pressure relief, spinal alignment, motion isolation, temperature regulation, and durability. We do not use any fancy gimmicks, proprietary scoring systems, or manufacturer-provided ratings. Each mattress is tested the same way so comparisons are fair, transparent, and based on actual performance, helping readers make informed, trustworthy buying decisions. Read our full mattress testing methodology!
- Bio-based memory foam comfort layer – plush cushioning without traditional memory foam drag
- Transition foam with zoned support – softer at shoulders, firmer under hips
- Pocketed coil support core – provides structure, airflow, and responsiveness
- Quilted performance cover – enhances breathability and softness
This blend gives the AS5 a deep-pressure-relief feel with a buoyant lift that keeps you from feeling “stuck” in foam.
💤 Comfort & Feel
The Amerisleep AS5 delivers plush, contouring comfort with a gentle hug that adapts to the body’s curves — especially around the shoulders and hips. This makes it ideal for sleepers who want a cloud-like feel without losing overall support.
What sleepers notice:
- Soft initial touch
- Gentle, body-hugging feel
- Smooth transition to support layers
This contouring quality is especially helpful for side sleepers who need extra give at the shoulders.

🧍 Amerisleep AS5 Mattress Review: Firmness & Support
The AS5 is rated around 4–5 out of 10, making it one of the softer mattresses available in the hybrid category.
Performance by sleep position:
- Side sleepers: Excellent pressure relief and contouring
- Back sleepers: Comfortable for lighter sleepers, but may feel too soft for some
- Stomach sleepers: Not supportive enough (excessive hip sink likely)
- Combination sleepers: Good for light-to-average weights, but may feel too plush for some shifts
The zoned support layer helps keep the hips lifted relative to the shoulders, but the overall softness still leans plush.
🌬️ Amerisleep AS5 Mattress Review: Cooling & Temperature Regulation
Hybrid construction and breathable cover help keep the AS5 cooler than typical all-foam beds:
- Pocketed coils allow airflow
- Performance cover wicks heat
- Bio-based foam sleeps slightly cooler than traditional memory foam
Though not as cool as latex or more ventilated hybrids, it’s definite improvement over dense foam.
🔁 Amerisleep AS5 Mattress Review: Motion Isolation (Couples)
The AS5 offers very good motion isolation for a hybrid:
- Plush foam cushions movement well
- Coil layer adds balanced responsiveness
- Slight bounce, but not overly disruptive
This makes it a solid choice for couples who want plush feel without excessive motion transfer.
🔧 Amerisleep AS5 Mattress Review: Edge Support
Thanks to the coil core, edge support on the AS5 is above average for a plush mattress:
- Better sitting edge stability
- Minimal roll-off when lying near the perimeter
- More secure than most all-foam plush beds
This is a plus if you sit or sleep near the edge frequently.
🪶 Durability & Longevity
Amerisleep’s combination of quality foam and a robust coil system suggests good long-term durability, especially for lightweight to average-weight sleepers.
- Coil support resists sagging
- Quality foams hold shape well
- Best for under ~230 lb sleep weights if plush feel preferred
Heavier sleepers looking for long-lasting support might prefer a firmer model.
🧾 Trial, Warranty & Policies
- 100-night sleep trial
- 15-year limited warranty
- Free returns during trial
These terms are stronger than many competitors and give buyers plenty of time to adapt.
✅ Pros & Cons
Pros
- Excellent pressure relief for side sleepers
- Plush, luxurious feel
- Good cooling for a foam hybrid
- Strong edge support relative to feel
- Good motion isolation for couples
Cons
- Too soft for strict stomach sleepers
- Not ideal for heavier sleepers needing firm support

🧠 Final Verdict of the Amerisleep AS5 mattress review
The Amerisleep AS5 is a great mattress for sleepers who want plush comfort with reliable support, particularly side sleepers and lighter individuals. Its soft, cushiony feel combined with zoned support and airflow-friendly hybrid construction makes it a strong choice for pressure relief and comfort. However, if you’re a heavier sleeper or primarily sleep on your stomach, you may find it too soft and might benefit from a firmer mattress.
In short: the AS5 excels at pressure relief and body contouring, but it’s not the best choice if you need strong firmness and spinal lift.
