Queen Size Mattress (One Year Only)

Very new queen-sized firm foam mattress only used it for one year, almost like brand new. Always have one layer of bedding then another layer of bed sheet on top of the mattress. The mattress is very well maintained. We are moving out and will switch to a king size bed. So I have to sell this one. Originally I bought it from Costco at $540. Smoke-free. Pick up around Sept 28 to Sept 30.
