Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS5 over the Stearns & Foster Estate Firm Tight Top. It scores higher in price-to-value and delivers stronger overall value. 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 (plant-based_memory_foam vs tight_top) — 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 9/10 (firm), and the Amerisleep AS5 sits at 3.5/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. On a Queen, the Amerisleep AS5 runs $1,849 versus $2,099 for the Stearns & Foster Estate Firm Tight Top — roughly $250 (12%) 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?

Firmness of 3.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 9/10).
Firmer at 9/10 vs 3.5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.
Cooling rating not available for one or both mattresses — spec not available.
Durability and edge-support ratings not available — spec not available.
Softer at 3.5/10 vs 9/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
Motion-isolation data not available for one or both mattresses — spec not available.
