Look up a site called Latex Sense.
I have two Latex mattresses in our house. One is in our room for our B&B and I often have guests asking me about the mattress as they find it so comfortable - a few have asked where they could get one.
When my hubby and I next buy a mattress we will be getting a Latex one. We currently have a mattress with two layers of pocket springs from John Lewis which is great - I got it in the sale at half price ( full price was over £1200) my side is medium and my husbands side is firm!!!
Latex keeps you cool and bugs can't live in it.
