We bought 2 years ago a full (hard) latex matress 6ft x 6,5ft, 8 inch high for 6.500 THB incl. shipping. They have a soft variant too.
After that my back problems gone.
It's funny to see what nonsens some people write here. Latex is to warm? I think this people never laid on a latex matress.
The onliest problem is that it is very, very heavy.
