- Material & Comfort: Memory foam is a popular choice at Costco, providing good support and pressure relief. Some models also have a gel-infused layer for cooling, which I appreciated since I tend to get warm at night.
- Cover: Removable and washable covers are a plus. Costco’s tri fold mattresses often come with soft, durable covers that make cleaning easier.

- Test if Possible: If you can visit a Costco warehouse, try lying down on the mattress before buying. It helped me decide which firmness level was right.
