Verdict: The Casper Wave Hybrid in performance with its pocketed‑spring system delivering 8‑point motion isolation (Sleepopolis) and superior cooling via built‑in airflow channels (Consumer Reports). However, Birch’s all‑natural latex construction offers strong edge support and a simpler, potentially longer‑lasting build, and it comes at a lower price point (Wirecutter). For most sleepers seeking natural materials and solid edge support, Birch is the better overall value, while hot sleepers or those prioritizing advanced zoned support may prefer Casper.
