Serta Perfect Sleeper Cascade Range review

Cascade Range is the Perfect Sleeper to buy if you want an innerspring rather than a hybrid. It uses Serta's 920-density Q4 Support System, the same coil count Serta lists for the Perfect Sleeper Hybrid, with 5 Zoned Comfort, a QuiltLoft memory foam quilt layer and a CoolFeel Plus cover with wool. Feels are Extra Firm and Medium at 14 inches, Firm Pillow Top at 14.5 inches and Plush Pillow Top at 15 inches. Serta's product data on November 10, 2026 put queens at $1,099 to $1,299, and a twin from $999. Serta lists it as best for back and stomach sleepers. The two cheaper Perfect Sleeper innersprings, Cascade Canyon and Cascade Ridge, use 860-density coils and cost less, with Cascade Canyon queens from $899. Pick Cascade Range when you want the bouncier on-top feel of coils and the extra firm option.
