Hi labella,
the prana uses latex which is the highest quality and most durable of all foams but having said that they are incredibly expensive compared to other latex mattresses that use similar quality materials. so thie issue is really one of value more than quality.
If you do a forum search on Prana it will bring up a few comments about them.
In post #11 here there is an analysis and review of the iComfort lineup (which I also don’t believe has good value).
There are some guidelines here which may help you avoid most of the pitfalls of mattress shopping and find better value.
If you let me know the city you live in I’d be happy to look and see if I know of any factory direct manufacturers or better outlets near you where you can get the help and guidance you need and probably also find much better value.
Depending on the size you are looking for … $2000 can buy you a very high quality mattress.
