Our Verdict
Saatva Classic
Helix Midnight Luxe 2025
The Helix Midnight Luxe 2025 is better than the Saatva Classic. The Helix is more supportive for most people, making it a better option for back/stomach sleeping. The better pressure relief also makes it better for lighter side sleepers. It's more cooling and better at dissipating motion, so you'll feel fewer of your partner's movements. It also contains more good-quality foam. That said, it's not as springy or responsive as the Saatva, so it doesn't feel as easy to move around on.
