Which has more firmness choices?

The Saatva Classic. It comes in Plush Soft, Luxury Firm and Firm. The Helix Midnight Luxe comes in one medium feel, rated 5-6 on the firmness scale.

Is the Saatva Classic worth the extra money?

At $1,599 at Saatva as of November 3, 2026, it costs more than the Helix's last low of $1,194. The extra buys three firmness options and a thicker Euro pillow top. If you already know you want a medium feel, the Helix covers that for less.
