Sweetnight Queen Mattress
Score: 82/100
Serta Sleeptrue
Score: 76/100Rankings
The Sweetnight SMN-THCD-12-Q is a 12-inch queen hybrid mattress featuring gel memory foam, a pillow-top, and individually wrapped coils for balanced medium-firm support and motion isolation. Its high weight and initial off-gassing are notable trade-offs. Ideal for couples and plus-size sleepers seeking premium comfort and cooling.
The Serta Sleeptrue Firm 11-inch hybrid combines custom coils with cool-twist gel foam for a firm, supportive sleep surface. Its main limitation is the lack of detailed trial or edge-support information, which may concern some buyers. Suited for back and stomach sleepers who prefer a firmer mattress.
