Choice recommended a number of different brands and mattress models/designs.
Valmori advertise 3 different designs. Spring, Hybrid, Latex Foam. The Choice review refers to the ‘Spring’ model only, evident from the Valmori website. The hybrid and latex were not reviewed.
I have moved your post to an existing topic which I believe your question falls under. There are many more topics related to mattresses. To find them, use the magnifying glass icon to search for mattress, or just click on the blue text.
As a side sleeper, I have decided to get the Sleep Republic Mattress. Not sure how warm it is compared to my current Ikea Hammarvik mattress. I was initially keen to get the Valmori mattress.

Anyway, it was already too late.
