Diamond Mattress Black Diamond Hybrid vs Tempur-Pedic TEMPUR-ProAdapt Medium Hybrid: What Actually Differs
Both the Diamond Mattress Black Diamond Hybrid and Tempur-Pedic TEMPUR-ProAdapt Medium Hybrid are hybrid mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type.

On a Queen, the Diamond Mattress Black Diamond Hybrid runs $2,599 versus $3,099 for the Tempur-Pedic TEMPUR-ProAdapt Medium Hybrid — roughly $500 (16%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about. The linked-seller trial periods aren't symmetrical either: the Diamond Mattress Black Diamond Hybrid is listed with 120 nights at Diamond Mattress; 30-night minimum; $99 fee, versus 90 nights at Tempur-Pedic; 30-night minimum; $175 return fee for the Tempur-Pedic TEMPUR-ProAdapt Medium Hybrid.

Both include a medium-range feel (Plush, Medium, Firm vs Medium), so either can work for back sleepers.

better long-term durability — the two specs heavier sleepers should weight most.
Plush, Medium, Firm includes the softer published option (vs Medium), which can make contouring easier for lighter sleepers.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
