We currently have a mattress from Arizona Premium, it’s about 5ish years old with a 3" talalay topper 19ild, and support core of 32ild blended latex. It’s a wonderful mattress, but I occasionally get hip numbness unsure if it’s mattress related but we are upgrading from a queen to a cal king and so I wanted to make sure doing the same ild numbers made sense. We can also do a split king with the size, I didn’t know if it made sense to do that.
Sleepers: female 5’5" 28 bmi, side sleeper
Male 6’5" 22 bmi back and side sleeper
We’re both in our 30s, also have the occasional 70lb dog sleeping at the end of the bed.
