For most sleepers, we recommend the Amerisleep AS5 over the Stearns & Foster Estate Firm Tight Top.

The Stearns & Foster Estate Firm Tight Top is the better choice only if you specifically prefer a firmer, more supportive feel.
Amerisleep AS5 vs Stearns & Foster Estate Firm Tight Top: What Actually Differs
The Amerisleep AS5 is a memory foam build, while the Stearns & Foster Estate Firm Tight Top is a hybrid — that single difference drives most of the cooling, motion, and feel decisions below. Profile-wise they're almost identical — the Amerisleep AS5 measures 14" and the Stearns & Foster Estate Firm Tight Top measures 14.5", so neither will dictate your sheet depth or bed-frame compatibility. The Stearns & Foster Estate Firm Tight Top is the firmer of the two at 7/10 (medium-firm), 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 edge support: the Stearns & Foster Estate Firm Tight Top rates noticeably higher than the Amerisleep AS5, which is the deciding factor if that dimension is high on your list. On a Queen, the Amerisleep AS5 runs $1,599 versus $2,099 for the Stearns & Foster Estate Firm Tight Top — roughly $500 (24%) 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 7/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 4/10).
Firmer at 7/10 vs 4/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Cooling rated the same on both — neither has a heat-management edge in our spec data.
better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weight most.
Softer at 4/10 vs 7/10 — 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.
