I don't know about the Englander which the other reviewers here had, but I bought the le Presidential Jackson FIRM and it is the best mattress I have owned in the last 20 years. I had a Costco mattress that lasted about a year and fell apart and I've tried several Sealy producst (some good). I'm 6' and 220 lbs, get a sore back easy, and a hot sleeper so it has been super hard for me to find a mattress. I've had this Presidential one about 2 years now and it is great. It was not very expensive (I think less than $500) so I was skeptical, but I love it and hope it's available next time I need a mattress. I would buy ten of them!
