RV short queen DynastyMattress foam mattress - $300 (college station)

Selling 12'' DynastyMattress CoolBreeze® Essential Sleep Air Gel Infused Memory Foam mattress.
Purchased about 6 months ago (can show receipt).
Went straight from manufacturer packaging to mattress protective cover.
Slept on for maybe 20 times.
Costs more than $600 at the time of this writing (see link).
Selling because the mattress is too firm for my taste, but this is a real, high density, high quality foam mattress, not one of those mattresses that immediately expand when you get off them.
Dimensions: 75"L x 60"W x 12"Th (short queen or RV queen).
Like-new, looks exactly like manufacturer picture.
Weighs at least 80lbs.
Buyer responsible for taking out of RV without damaging RV and transportation, so bring help.
Cash, Zelle, or Venmo.
