The Helix Midnight and Casper Original are two of the most searched mattresses in the $1,000-$1,300 range. But they take fundamentally different approaches: Helix builds mattresses for specific sleep types, while Casper designs for universal comfort. For side sleepers, this difference matters a great deal.
Construction Breakdown
Helix Midnight
Helix Midnight is a hybrid mattress with:
- Polyfoam comfort layer
- Memory foam pressure relief layer (targeted for side sleepers)
- Individually wrapped pocketed coils
- Dense foam base
Firmness: Medium (5/10) — specifically calibrated for shoulder and hip pressure relief.
Casper Original
The Casper Original (foam version) uses:
- Polyfoam top comfort layer
- Zoned support foam (firmer under lumbar, softer under shoulders)
- High-density foam base
Firmness: Medium (5.5/10) — designed to work for multiple sleep positions.
Note: Casper also offers a hybrid version for ~$200 more. This comparison covers the standard Original foam model.
Where Helix Midnight Wins
- Side sleeper specialization — Memory foam layer is explicitly designed for hip/shoulder relief
- Bounce / responsiveness — Pocketed coils make repositioning easier than all-foam
- Cooling — Coil airflow base sleeps noticeably cooler than Casper's foam-only construction
- Couples — Split king option allows different firmness per side
Where Casper Original Wins
- Zoned support versatility — Works well for back sleepers too
- Motion isolation — All-foam construction absorbs movement better than hybrids
- Brand ecosystem — Casper's full sleep product line integrates well

The Case for Upgrading to Saatva Classic
Both Helix Midnight and Casper Original offer 100-night trials. For a few hundred dollars more, the Saatva Classic offers a 365-night trial, white-glove delivery, and a coil-on-coil construction that outperforms both in long-term durability. If budget flexibility exists, the Saatva Classic is worth the step up.

Is Helix Midnight good for couples with different sleep preferences?
