The Casper Original Mattress is a standalone all-foam mattress offering good motion isolation and zoned support, suitable for various sleeping positions. However, it may have potential off-gassing and heat retention issues. The Eight Sleep Pod 3 Cover transforms an existing mattress into a smart bed with advanced temperature control and sleep tracking, but it suffers from high motion transfer and requires careful setup. The choice depends on whether you prioritize a complete mattress replacement or adding smart features to your current setup.
