Here is what I am looking for:

A natural latex matress under $2000. I am 5' 4" and 118 lb. I am a side sleeper most of times. I do have some lower back problems due to a slight herniated disc and i don't like really firm matresses or soft ones. We always had a pillow top and I like a cushion feeling. I am looking at the king matress sizes and wondering if there is a big difference between the 8 inch, 8500 model and 10000 model. I am planing to call SleepEZ and also look at some latex mattresses in the stores like room and board. I live near Irvine,ca and can also check out foam sweet foam to feel their mattresses for research purposes. I have already checked a matress store called Ergo and found their prices too high and their sales staff not that informative. Thank you for any help in this matter.
