About the Casper The One Mattress Bundle
The Casper The One Mattress Bundle pairs an all-foam mattress with a tool-free Foundation and a waterproof mattress protector, sold as one set. The One is the firmer, simpler option; the bundle also lets you swap in the thicker Cloud One for more cushioning. In Full size the set is $1,002.30 at Casper as of November 4, 2026, the only new price listed, so there is no cheaper store to compare against. Buying the pieces separately usually costs more than the bundle, which is the main reason to take the set.
Best forFirst-time mattress buyers who want the frame and protector in one orderBack and stomach sleepers who prefer a firmer all-foam feelGuest rooms and spare bedrooms that need a complete setupShoppers who want a simple online purchase with delivery
Pros
- Foundation assembles in minutes without tools
- Waterproof protector included, so no separate purchase
- All-foam build with continuous support and no springs to wear out
- Firmer feel that suits back and stomach sleepers
- One order covers mattress, base and protection
