Spot the Feature Dump: Teardown of a Mattress Product Page

Casper Sleep

Objective: Given a synthetic mattress product-page copy block, identify every line that lists a feature without a benefit translation, and diagnose why each one will underperform.

You're a freelance copywriter auditing product-page copy for a mattress brand before a paid traffic campaign launch.

Read the specimen copy block, mark each defect using the feature-vs-benefit framework, and use the So What Test to find the buried benefit.
