Need Help Deciding?
For most sleepers, we recommend the GhostBed Flex over the Amerisleep AS5. It scores higher in cooling, edge support, price-to-value and delivers stronger overall value. The Amerisleep AS5 is the better choice only if you have a strong preference for that brand's specific feel or design.
Amerisleep AS5 vs GhostBed Flex: What Actually Differs
The Amerisleep AS5 is a memory foam build, while the GhostBed Flex is a hybrid — that single difference drives most of the cooling, motion, and feel decisions below. The Amerisleep AS5 stands 14" tall versus 13" for the GhostBed Flex — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The GhostBed Flex is the firmer of the two at 5.5/10 (medium), and the Amerisleep AS5 sits at 4/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in cooling: the GhostBed Flex rates noticeably higher than the Amerisleep AS5, which is the deciding factor if that dimension is high on your list. On a Queen, the GhostBed Flex runs $1,249 versus $1,599 for the Amerisleep AS5 — roughly $350 (22%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Firmness of 5.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 4/10).
Firmer at 5.5/10 vs 4/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Stronger cooling rating, which matters most for sleepers who run hot or live in warm climates.
stronger perimeter / edge support — the two specs heavier sleepers should weight most.
Softer at 4/10 vs 5.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
