Published 3/5/2025
Build philosophy
Casper Original: All-foam construction with a top comfort layer and zoned support foam underneath. Built for broad appeal at a moderate price.
Casper Hybrid: Same foam stack with individually wrapped coils added underneath for more support and airflow.
Secret Mattress: Hand-sewn hybrid with quilted top, contouring foam comfort layers, and individually wrapped coils. Made in the USA with traditional craftsmanship.
Who each one fits best
Casper Original: Light-to-average weight sleepers (under 200 lbs), couples who prioritize motion isolation, anyone who likes a 'neutral' foam feel.
Casper Hybrid: Sleepers who want the Casper feel with extra airflow and edge support.
Secret Mattress: Sleepers who want a true hybrid feel, hot sleepers, heavier sleepers needing deeper coil support, and buyers who value American hand-sewn craftsmanship.
Durability
All-foam mattresses (like Casper Original) typically show body impressions sooner than hybrids — usually within 5-7 years.
Hybrid mattresses with quality coils, including Secret Mattress, are designed to last 8-10+ years and are backed by the 10-year no-sag guarantee.
Frequently asked questions
- Is the Casper Original or Secret Mattress better for hot sleepers?
- Secret Mattress. The coil base allows airflow that the all-foam Casper Original can't match. If you compare against the Casper Hybrid specifically, the difference is smaller — but Secret Mattress's thinner foam comfort layer still gives it a cooling edge.
- Which has better edge support?
- Hybrids win here. Both Secret Mattress and Casper Hybrid have reinforced edges from their coil construction; the all-foam Casper Original has noticeably softer edges.
