Get Casper Sleep if
You want the cheaper, edge-supported hybrid and can live with buying the last of a discontinued run — Casper invented the bed-in-a-box category but no longer sells this model.
Get Helix Midnight if
You want the internet's #1-ranked side-sleeper hybrid — deep pillow-top over coils, made-to-order in the US.
Tied on
Both are medium-feel hybrids over pocketed coils. Both target the pressure-relief buyer. Both are 6/10 medium.

Deeper pillow-top and coils optimized for side sleeping, a 365-night trial (on orders from Helix's own site) against 100, a limited lifetime warranty against Casper's 10 years — and it is still in production. Casper has discontinued the Original Hybrid, so what's left is limited Amazon stock; it still wins on edge support and on price.
Deep dive
This is the Helix Midnight Luxe's specific mission. 13.5″ luxe profile, quilted memory foam pillow-top, coils zoned to firm at hips and soften at shoulders, tuned for side sleepers in the 130-230 lb range. Sleep Foundation names it their best mattress overall.
Casper Original Hybrid is also solid for side sleepers (zoned coils, medium feel, 11″) but the pillow-top is shallower. Side sleepers with shoulder pressure issues: Helix.
This flips once you look at what's actually on top of each bed. Helix Midnight Luxe ships with a GlacioTex cooling cover — a dedicated cooling surface, not just a breathable knit — over the memory-foam pillow-top. Casper's AirScape is perforated foam that vents heat passively, which beats a solid memory-foam slab but is not an active answer.
Casper's own listing settles it: "cooling is average — hot sleepers look elsewhere" is the first drawback on its page. Helix is temperature-neutral rather than cold, and the quilted foam pillow-top that delivers the pressure relief is still the layer that holds the most heat, so don't read this as a large gap.
We haven't run thermal testing on either bed and won't quote a temperature difference. If you sleep hot and need side-sleeper pressure relief, Helix is the better of the two — but a grid-topped or actively cooled bed is a different conversation.
Casper's perimeter coils are firmer than Helix's, which matters for two use cases: (1) sitting on the edge to tie shoes without feeling like you'll roll off, and (2) making full use of the mattress width (some memory foam beds feel like you'll fall off the sides).
Helix has decent edge support but Casper's is notably better. Couples who use every inch of the mattress: Casper wins here.
Helix: 365-night trial on orders from its own site, limited lifetime warranty. Casper: 100-night trial, 10-year warranty. Mattresses that are going to fail sag around years 8-12, so open-ended coverage genuinely covers the risk period in a way a 10-year clock doesn't.
The bigger difference is that only one of these is still made. Casper has discontinued the Original Hybrid: casper.com now redirects it to the Casper Dream Hybrid, and GoodBed lists the Original among Casper's discontinued models. What remains is Amazon stock under ASIN B085H9FBBP, flagged as limited quantity. Helix Midnight Luxe is built to order in the US and ships in a few business days.
For many buyers that outweighs the price gap, which is now wide: the Casper costs about half as much. A 10-year warranty on a discontinued line has no current-production unit to exchange into, and if the bed doesn't suit you there's no Casper-direct replacement — you'd be moving to the Dream Hybrid, which is a different mattress at a different height and price.

Helix Midnight Luxe, and it's not close. The deeper 13.5″ pillow-top and shoulder-zoned coils are specifically tuned for side sleeping in the 130-230 lb range. Casper is fine but Helix is the benchmark — and it's the one still in production.
Helix Midnight Luxe. It ships with a GlacioTex cooling cover; Casper's AirScape foam only vents heat passively, and Casper's own listing names average cooling as its first drawback. Neither is a specialist cooling bed, and we haven't measured a temperature difference between them.
Casper. Firmer perimeter coils = better for sitting on the edge and making use of the full mattress width. Helix rates its own edge support as mid-pack.
Casper, which costs less than the Helix. But that's the price of discontinued Amazon stock rather than a live product line, so weigh the saving against having no brand-direct support if it doesn't work out.
Helix on paper — a limited lifetime warranty against Casper's 10 years. Both beds are rated for 10+ years of service, so the practical difference is coverage rather than construction. Note that Casper's line is discontinued, which makes a long-tail warranty claim harder to service.
Not from Casper. As of July 2026 casper.com redirects the Original Hybrid to the Casper Dream Hybrid, and Casper's own upgrade guidance points Original owners there. Remaining stock is on Amazon (ASIN B085H9FBBP) in limited quantity. Helix Midnight Luxe is made to order and unaffected.
Helix runs a 365-night trial on orders from its own site; Casper runs 100 nights. Both require roughly 30 nights of sleep before a return can start, so the usable decision window is about 335 nights on Helix and 70 on Casper.
