Hi Diana

The only model we have in our ranges with pocket springs and latex, is the Origins Pocket Latex 1500.

This will offer a firm feel for someone of 65kg, a more medium feel for someone of 80kg.

We also produce this model in 2000 springs, which would be a firm feel for the 80kg body weight, so you could look at getting the zip link option with one side 1500 springs, and one side 2000 springs.

If you require any further assistance please call the office.

Kind Regards Gary
