The Serta Perfect Sleeper Midsummer Nights is a plush tight-top queen innerspring mattress built on an 825-coil density system. A lumbar gel support band adds zoned support through the middle, and Cool Twist gel memory foam contours while moving heat away. It suits side and back sleepers who want a soft, conforming feel with spring support underneath. Against other plush hybrids and innersprings, it leans on coil count and a cooling gel layer rather than thick foam stacks, so it feels more traditional than all-foam rivals.
