My family just moved out of EV and we are selling the memory foam toppers that literally SAVED our backs for the last two years.

We bought the items at Costco. You can see a description in the link below:

We have a queen and a twin topper.
Prices:
Queen $70 ($150 at Costco)
Twin $50 ($100 at Costco)
Queen + Twin $100 (perfect if you live in one of the low rises and have a child).

The queen topper is two years old and the twin is just 4 months old. They are both perfectly clean and in great condition.

Items are available for pickup in Menlo Park, very near campus.
