Our Verdict
Casper Snow
Helix Midnight Luxe 2025
The Casper Snow and Helix Midnight Luxe 2025 have different strengths. Both have a medium firmness level, but you may prefer the Casper if you like feeling enveloped by your mattress, since it has a higher sinking level. The Casper offers much better cooling and motion isolation, but has slow responsiveness, so you may feel stuck in place. The Helix is much more responsive and has better edge support, making it easier to get in and out of bed and more comfortable to sleep near the edge of the bed.
