King Size Mattress - $1 (Poland, Ohio)

I have a king size mattress and several bases, it is a plush mattress i bought it in November 2023 and to be totally honest with you, it is too soft, i have tried different bases, mattress toppers anything i could think of, but i have back problems and it is just not right for me, so we have to go back down to a queen, i don't know what they are worth, so please make an offer in November of 2023 i paid $1,450 for the mattress and then the variety of bases were purchased seperately, i know i will not get that, but just make an offer,
