Step-by-step inspection to detect mid-production substitutions and compare component specs.
- 01
Weigh Value vs Long-Term Longevity
Buy from Costco if you want unbeatable value ($649) and a 100% refund policy at any time.

Check Retail Version for Back Pain
Choose the retail Posturepedic Plus (1,072 coils) if you suffer from severe chronic back pain.
Watch for: The lower coil count in Costco models provides less granular zoned contouring.
- 03
Keep Costco Membership Active
Costco accepts mattress returns for a full refund even after years of use if dissatisfied.
Watch for: Retail mattress stores charge return pickup and restocking fees.
