Casper's Foam Mattress Topper applies the same zoning concept as the Casper Wave mattress: firmer under the hips, softer under the shoulders. For side sleepers whose mattress is too firm overall, this zoning means the spine stays aligned without a shoulder pressure point. At 1.5 inches it softens without overwhelming a firmer mattress.

The Casper Foam Topper applies the zoning concept from the Casper Wave mattress to topper form: softer at the shoulder zone, firmer at the hip zone. For side sleepers whose mattress is too firm overall, this targeting is the correct mechanical response — the shoulder sinks in slightly while the hip maintains support, keeping the spine level.
At $175, it sits at a fair price point for the quality. The open-cell memory foam provides marginally better airflow than standard closed-cell foam, though heat retention remains a consideration for hot sleepers. The 30-night trial and 1-year warranty are the weakest aspects of the package.
