Our Verdict
Helix Midnight Luxe 2024
Sealy Posturepedic Hybrid
The Helix Midnight Luxe 2024 and the Sealy Posturepedic Hybrid are both medium-plush mattresses and have similar levels of bounce, sinking, and contouring. They perform similarly, but the Helix is more responsive, making it easier to change sleeping positions. It uses zoned coils, so it's a bit firmer in the lumbar area.
