Bought from Costco this January for $600, only about 10 months old. Selling because I'm moving in December.
Comfortable, supportive 14-inch gel memory foam, taken good care of and kept clean. No stains. Comes with the mattress bag and I'll help you load it into your car.
Why it's a good deal: a $600 Costco mattress for a third of the price, barely used.
