Amerisleep AS5 vs Casper The Dream Hybrid: What Actually Differs

The Amerisleep AS5 is a memory foam build, while the Casper The Dream Hybrid is a hybrid — that single difference drives most of the cooling, motion, and feel decisions below. The Amerisleep AS5 stands 14" tall versus 12" for the Casper The Dream Hybrid — a 2.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Casper The Dream Hybrid 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 motion isolation: the Amerisleep AS5 rates noticeably higher than the Casper The Dream Hybrid, which is the deciding factor if that dimension is high on your list. On a Queen, the Amerisleep AS5 runs $1,599 versus $1,895 for the Casper The Dream Hybrid — roughly $296 (16%) 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?

Side sleepers
Amerisleep AS5

Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.

Back sleepers
Casper The Dream Hybrid

Firmness of 5.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 4/10).

Stomach sleepers
Casper The Dream Hybrid

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.

Hot sleepers
Either works

Cooling rated the same on both — neither has a heat-management edge in our spec data.

Heavier sleepers (230+ lb)
Either works

Durability and edge-support ratings are equivalent — either holds up.

Lighter sleepers (under 150 lb)
Amerisleep AS5

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.

Couples / light sleepers
Amerisleep AS5

Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
