Wow, and here I thought I had an expensive mattress. $20K?
I had a few too many glasses of wine on my wedding anniversary a couple years ago, and ordered a high-end, king sized Sleep Number bed off QVC, for $3K. A few days later FedEx dropped off 7 huge boxes on my doorstep, so no problem getting it upstairs to the bedroom.
Still, it is amazingly comfortable; so much so that I almost hate getting out of bed in the morning. Probably one of the best investments I've made. I used to wake up every day feeling worse than when I went to sleep. No longer.
