What is the best Costco mattress?

Best overall Costco mattress for most people: Kirkland Signature by Stearns & Foster Lakeridge. It’s a strong value pick if you want a more traditional, substantial-feeling hybrid mattress with Costco’s easy buying/return experience.

If you prefer a softer foam feel, choose Novaform ComfortGrande Advanced Gel Memory Foam. If you want a cooler, more premium hybrid, look at Casper Snow Max Hybrid or Tempur-Pedic Supreme options at Costco when available.
