Hi sidesleeper,
That’s unfortunate. I’m not sure where you live but in those areas of the country where there aren’t any good options available locally then I would generally suggest some of the better online options that have good exchange or return/refund options available after a purchase just in case a purchase doesn’t turn out as well as you hoped for.
There is more about the different ways to choose a mattress (online or local) that can help reduce the risks of each of them in post #2 here (although I realize that this won’t help you with your current circumstances so it would be more for future reference)
