I'm disappointed given the headline that there wasn't any mention of the make of mattresses that are being stolen. We bought a new mattress about a year ago and sampled some in the $20K+ (yes!) range just for the fun of it. If these are legit 5 star luxury hotels experiencing mattress theft, they could be of the same cost variety. We like our much less expensive one a lot better, even if it isn't the same model that was on the Titanic or used by royalty.
There's a local retailer that sells "natural" latex mattresses for about $2200.
You can find sites online where you can buy all the components and make your own latex mattress ("make" being stack the components in the outer shell and zip it closed) for under $500 shipped.
