My wife and I are in the market for a larger bed since our bed is now shooting springs into our backs

I was online randomly looking at King-sized beds (on Ripley's website)... knowing that they are ridiculously overpriced.
I am wondering if anyone has any bed suggestions, and purchase location suggestions. The money Ripley's is asking for seems a bit unrealistic. But, maybe I am the unrealistic one.
Thanks for the suggestions!
