Purple (Original)
- ✓ GelFlex Grid is genuinely unique — soft where you need it, firm where you don’t
- ✓ Best cooling of any foam mattress (no heat trapping)
- ✓ Pressure relief for side sleepers
- ✓ $196 cheaper (Queen)
- ✗ Grid feel is unusual — some people don’t like it
- ✗ Less edge support than foam alternatives
- ✗ Lighter sleepers may feel “stuck” in grid
Casper Original
- ✓ More widely loved feel — gradual foam adaptation
- ✓ Taller 11″ profile
- ✓ Better edge support
- ✓ More traditional mattress feel for those transitioning from innerspring
- ✗ $196 more expensive
- ✗ Foam can sleep warmer than grid
- ✗ Less unique pressure relief than Purple
Final Verdict
The Purple Original is genuinely unlike any other mattress — the GelFlex Grid polymer responds dynamically to pressure, provides excellent pressure relief for side sleepers, and because the grid allows air circulation, it sleeps measurably cooler than foam. Hot sleepers and side sleepers should seriously consider it. The Casper Original has a more traditional, gradually-contouring foam feel that converts innerspring sleepers more comfortably. If you sleep hot: Purple. If you want a trusted foam feel: Casper.
