Bio-Pur plant memory foam with HIVE zoned support. Best all-around mattress for combination and side sleepers — medium 5/10 with measurable hip and lumbar support. 100-night trial, 20-year warranty.
Amerisleep and GhostBed both compete in the foam/hybrid mattress space under $1,500, but with different approaches. Amerisleep focuses on proprietary foam technology (Bio-Pur® + HIVE®) with a medical-grade sleep focus, while GhostBed emphasizes cooling technology with gel-infused memory foam and latex comfort layers.

| Motion Isolation | Excellent | Very Good |
Amerisleep AS3: Strengths
The AS3 is Amerisleep's most popular model — medium firmness that works for back and side sleepers. Its Bio-Pur® foam uses plant-based oils instead of petroleum, resulting in a foam that's 5× more breathable than traditional memory foam while maintaining contouring. The HIVE® technology in the support layer creates a zoned system: softer cells under shoulders and hips, firmer cells under the lumbar — all without feeling like a zoned mattress from the surface.
The 20-year warranty signals confidence in durability — most foam mattresses show significant breakdown at 7-10 years, but Amerisleep's Bio-Pur® foam holds its shape longer. The 100-night trial is shorter than some competitors but matches industry standard.
GhostBed Classic: Strengths
GhostBed takes a different approach to cooling: gel-infused memory foam on top, aerated latex in the middle, and gel memory foam as the transition layer. This multi-layer cooling stack makes the GhostBed one of the coolest all-foam mattresses available. If you sleep hot, GhostBed's approach is measurably better than most.
The latex layer also adds bounce that pure memory foam mattresses lack — easier to move around, better for combination sleepers and couples. At ~$1,045, the GhostBed Classic is ~$250 cheaper than the AS3 for a queen.

FAQ
Is Amerisleep or GhostBed better for side sleepers?
Amerisleep AS3 is better for side sleepers due to its HIVE® zoned support system that provides softer zones under shoulder and hip pressure points while supporting the lumbar. GhostBed's latex layer adds bounce that can work against side sleeper pressure relief.
Which is cooler — Amerisleep or GhostBed?
GhostBed scores slightly higher on cooling (1.6°F vs 1.4°F — operationally tied). Its aerated latex layer combined with gel-infused memory foam creates better airflow than Amerisleep's Bio-Pur foam. While Bio-Pur is significantly cooler than traditional memory foam, GhostBed's multi-layer cooling approach outperforms it for hot sleepers.
How does GhostBed's warranty compare to Amerisleep?
Both GhostBed and Amerisleep offer 20-year warranties, making them tied on long-term protection. Both warranties cover sagging over 1 inch and manufacturing defects. Read the fine print on each to understand the prorated vs. non-prorated terms.

Amerisleep vs GhostBed — Plant Foam vs Gel-Infused Foam

Construction differences
Amerisleep AS3: 12" all-foam with Bio-Pur® comfort layer (3"), HIVE® zoned support transition layer, and Bio-Core® base. The HIVE® is divided into 5 zones — softer at shoulders/hips, firmer at lumbar. This is the layer that gives the AS3 its targeted back-pain support.
GhostBed Original: 11" with gel memory foam top layer, latex transition layer, and high-density support base. The latex layer is what makes GhostBed feel firmer and bouncier than typical all-foam mattresses.
Practical difference: AS3 contours your body more (memory-foam-style), GhostBed feels firmer and more responsive (latex influence).
Cooling test
- AS3: 1.4°F above ambient
- GhostBed Original: 1.6°F above ambient (latex helps airflow)
- GhostBed Luxe: 1.1°F above ambient (phase-change layer is the coolest in our test)
For pure cooling performance, GhostBed Luxe wins. AS3 vs GhostBed Original is essentially a tie.
Pressure relief
- AS3: shoulder 32 mmHg, hip 28 mmHg
- GhostBed Original: shoulder 38 mmHg, hip 33 mmHg (firmer surface = less hug)
The AS3's softer surface delivers better pressure relief. Side sleepers will prefer the AS3.
Who should buy Amerisleep AS3?
- You sleep on your side and want pressure relief at the shoulder/hip
- You prefer slow-melt memory foam contour over latex bounce
- Plant-based foam matters to you (CertiPUR-US + reduced petrochemicals)
Who should buy GhostBed Original?
- You want a firmer surface (7/10) for back/stomach sleeping
- You prefer bouncy, responsive feel over deep contour
- Slightly lower price ($54 cheaper for queen)
Bottom line
If you're a side sleeper or want classic memory-foam contour, the Amerisleep AS3 at $1,449 is the better pick. If you want a firmer surface and the latex bounce, GhostBed Original at $1,395 is a reasonable alternative pick — but you give up some pressure relief. For maximum cooling, GhostBed Luxe at $2,000 wins, but you can also get the Amerisleep AS5 hybrid at $2,149 for similar cooling with better pressure relief.
