Right now I'm considering Zoltan's Kingsdown but in the Malbec.
Also looking at Royal Pedic.

This would be a $6K bed but it would be the last bed I buy I'm sure. I like to see the "little" things that the very rich buy. Bath towels, certain clothing... basic essentials that are relatively cheap but something an 8 figure person might own. A Royal Pedic might be one of these things and may be worth it. I'm not a big house kind of person but experiential. Experiencing sleeping on a handmade mattress may actually be worth the cost of entry.
At the opposite end, Costco has a S&F for $1K which I would consider a 3 to 5 year mattress. not great value. Certainly nothing compared to mine lasting forever.
