The quick verdict
This is a three-way extension of our head-to-head Purple vs Casper comparison. If you only care about those two, that page goes deeper on each.
Cheapest of the three on sale, firmest feel, longest warranty. Great for back and stomach sleepers.
Softer and more contouring than GhostBed. The safe pick if you sleep on your side.
The grid is in a class of its own for airflow and bounce, at the highest price.
GhostBed is the value play for people who want a firmer, cooler foam bed and don't need the softest feel. Casper is the softer all-rounder. Purple is the premium outlier for hot and combination sleepers.

GhostBed runs sitewide discounts of 25–30% almost continuously, so its real-world price is usually the lowest here. Casper's One is close behind on sale. Purple discounts the least.
Feel and firmness
GhostBed Classic: firm, latex-topped, cool
The GhostBed Classic is an 11-inch all-foam mattress, but it doesn't feel like a typical memory-foam bed. The top layer is aerated synthetic latex, which is springy and doesn't trap heat. Under that is a gel memory foam layer, then a dense support core. The net effect is a medium-firm (most testers put it around 6.5–7/10) surface with bounce, minimal sink, and better-than-average cooling for a foam bed.
Back sleepers and stomach sleepers are the sweet spot. Lighter side sleepers often find it too firm to relieve shoulder pressure. GhostBed also sells a Luxe (softer, more cooling tech) and hybrid models if the Classic is too firm.
Casper One: softer and more forgiving
Casper's entry-level bed is a medium (5/10) all-foam mattress with Zoned Support — softer foam under the shoulders, firmer under the hips. It contours more than GhostBed, which is why it's the better side-sleeper option. It sleeps warmer than GhostBed and doesn't have the same bounce.
Purple: the grid
Purple's GelFlex Grid is unlike either foam bed. It buckles under pressure points and stays firm elsewhere, with open channels that make it the coolest-sleeping bed here. Very responsive, very bouncy, slightly polarizing texture. Medium (6/10) overall.
Firmness ranking, softest to firmest: Casper One → Purple → GhostBed Classic.
Cooling: the real differentiator
All three market themselves as cooling. In practice:
- Purple is the clear winner. The grid is mostly air. If you overheat at night, this is the one.
- GhostBed Classic is a strong second. Aerated latex on top plus gel foam underneath keeps it noticeably cooler than a standard memory-foam bed. It's the best-cooling all-foam option of the three.
- Casper One is fine, not special. AirScape perforated foam helps, but it's still a contouring foam bed that holds some heat.
If cooling is your top priority and the Purple price is too high, GhostBed is the smart compromise.

|---|---|---|---|
| Side sleeper | Best | Good | Too firm for many |
| Back sleeper | Good | Great | Great |
| Stomach sleeper | Too soft | Good | Best |
| Combination sleeper | Okay | Best | Good (bouncy latex helps) |
| Hot sleeper | Fair | Best | Very good |
| Heavier sleeper (230+) | Sinks | Good | Good |
| Budget-first buyer | Good on sale | Priciest | Best on sale |

GhostBed Classic
Latex-topped, cool-sleeping, medium-firm foam bed with a 20-year warranty. Usually the cheapest of the three on sale.

The GelFlex Grid: unmatched airflow and bounce. Premium price, premium cooling.
Who should buy which
GhostBed if you sleep on your back or stomach, run warm, and want to spend the least. Casper if you sleep on your side and want a familiar, forgiving foam feel. Purple if you sleep hot enough that nothing else has worked, or you're a restless combination sleeper.
